The Scientific and Technological Research Council of Turkey (TUBITAK) Academic Research Funding Program Directorate (ARDEB) Electrical, Electronics and Informatics Research Grant Committee (EEEAG) and the Portuguese Foundation for Science and Technology (FCT) funded bilateral research project (TUBITAK ARDEB Grant no: 115E591) (acceptance rate of the related bilateral project call: 6%)
Software development, required for constructing multi-agent systems (MAS) usually becomes challenging and time-consuming due to autonomy, distributedness and openness of these systems in addition to the complicated nature of internal agent behaviors and agent interactions. To facilitate MAS development, various domain-specific modeling languages (DSMLs) are proposed in the Agent-oriented Software Engineering (AOSE) research field. These DSMLs are supposed to meet software development requirements of both MAS DSML developers and MAS DSML users. Moreover, they should be evaluated to determine how they both speed up and facilitate MAS development. Although the descriptions of these languages are given in the related studies with the examples of their use, unfortunately, many of them are not evaluated either in terms of usability or quality of the generated artefacts. The evaluations in the remaining studies are made in an idiosyncratic manner without any comparison to meet developer expectations. In order to fill this gap in the AOSE research, an evaluation framework, called AgentDSM-Eval and its supporting tool, which can be used to evaluate MAS DSMLs systematically according to various quantitative and qualitative aspects of agent software development, were developed in this project. During the quantitative evaluation inside the AgentDSM-Eval tool, MAS domain coverage is determined by comparing a DSML’s metamodel with a reference MAS metamodel. In the second part of the quantitative evaluation, which is constructed on a multi-case study, the software development time and the artifact generation performance are taken into account. Finally, based on MAS developers’ feedback, the qualitative evaluation of the language is performed according to some quality metrics. Use of AgentDSM-Eval and its tool was exemplified with the evaluation of Prometheus/PDT, a well-known language in AOSE. In addition, the Analytical Hierarchy Process (AHP) based comparative evaluation method, supporting the multi-criteria decision making, was used for the evaluation of four widely used MAS DSMLs and favourite DSML for each comparison category and criteria was determined within this evaluation.

Device tree (DT) files, which include hardware information and configuration, are used during the compilation of operating systems for various embedded platforms. DTs provide description of physical devices and peripherals inside an embedded system hardware with node specifications. However, software developers mostly have difficulties in developing such applications due to text-based syntax of DT source files which has a different structure from the well-known general purpose programming languages. For each new embedded platform, specific DT files should be coded separately from scratch. Furthermore, the developer needs to be familiar with the hardware specific for each different microprocessor to prepare such files. That process can be very challenging for the developers who possess domain knowledge for these hardware but little or no experience on software development. Moreover, both development and configuration of DT software components regarding different microprocessor architectures can be very hard and time-consuming. In order to eliminate these deficiencies and difficulties of current DT software development processes, a model-driven software development (MDSD) methodology in which automatic generation and configuration of DT software for different embedded platforms is provided. Within this context, a domain-specific modeling language (DSML), called DSML4DT, with including all supporting visual modeling and automatic code generation tools for the application of the proposed MDSD methodology were developed in the project. Various noteworthy studies exist in the related research field for the model-driven development and/or the generation of codes for hardware drivers in the embedded systems. However, these studies do not take into account the development of DT-based software. The work herein provided the achievement of the initial artifacts in order to bridge the abovementioned gap encountered in the field. The evaluation of DSML4DT was performed over the development of DT software for four different embedded devices. The comparative evaluation results showed that a significant amount of the code required for DT software can be automatically achieved by using the DSML4DT. The time needed to develop DT software was reduced to half by applying the MDSD methodology and using DSML4DT. Finally, qualitative assessment, based on the developers’ feedback, exposed how DSML4DT facilitates DT software development.

Many developers prefer constructing software for Internet of Things (IoT) due to their low cost hardware requirements and variability of application domains. One of the popular operating systems underlying the IoT systems is Contiki operating system (ContikiOS). The unique lightweight thread structure of Contiki makes it more preferable in the implementation of new IoT systems instead of many other existing platforms. Although operating systems play the role of an abstraction layer for low level hardware, heterogeneity, distributed programming and network related concerns dominate the workload in software development. The separation of hardware-related and application-related concerns will improve the software engineering processes of IoT systems which may pave the way to deal with the system's structural complexity coming from the heterogeneity. One possible approach to cope with this complexity is to increase the abstraction level using system models, for IoT in a Model-driven Development (MDD) approach. MDD moves software development from code to models and may increase productivity and reduce development costs. Although MDD for IoT systems is being researched in several studies especially for the purpose of separation of concerns, most of them do not provide a complete and/or a systematic approach for their MDD solutions. Moreover, these studies do not consider the MDD of IoT on ContikiOS. Hence, in this project, design and implementation of a ContikiOS-based IoT system are realized according to MDD principles. The case study is the development of a smart library fire detection system.

The methodology applied in the current agent domain-specific modeling language (DSML) development approaches for the derivation of operational semantics unfortunately requires the definition and implementation of new model-to-model (M2M) and model-to-text (M2T) transformations from scratch in order to make the DSMLs functional for different agent execution platforms. For each new target agent execution platform, agent DSML designers should repeat all the time-consuming and mostly troublesome steps of preparing the vertical transformations between the related DSML and this new agent platform. Instead of applying this methodology, both the definition and the implementation of M2M transformations between the metamodels of MAS DSMLs may be more convenient and less laborious in the way of enriching the support of agent DSMLs for various agent execution platforms. Hence, this project aims at improving the mechanism of constructing language semantics over the interoperability of agent DSMLs and hence providing a more efficient way of extension for the executability of modeled agent systems on various underlying agent platforms. The project also covers investigating the applicability of the proposed DSML interoperability approach by constructing horizontal transformations between full-fledged agent DSMLs.

One of the most challenging parts of video streaming systems running on a peer to peer network is to cope with dynamic network conditions and unpredictable node behaviors. Therefore, in an overlay network, different paths are created from source to destination and when packet transmission problems occur in one video streaming path, destination node continues receiving packets on the other path. However, it needs to be determined whether designed path diversity or selected streaming path(s) is optimal in terms of video quality and path bandwidth. A system, based on the software agents with autonomous, reactive, proactive and social features, may be suitable for solving the selection problem of alternative paths in peer to peer video streaming systems. Hence, in this project, a new path selection system based on agents was developed in order to increase service quality of nodes in a peer to peer video streaming system. Both the construction of an overlay network and the development of the internal architecture of agents were realized. Connection between the nodes in the streaming network and the software agents were set up in order to provide agent-based selection of alternative paths. Logical path selection method, developed in this project, enables nodes to infer on the capacity and robustness of the other nodes based on the reinforcement learning. Another approach brought by the project considers the assessment of the physical paths between a node and its parents. According to the simulation results, it can be said that the proposed method performs much better than the existing methods considering all criteria on both quality of experience and network conditions.

Software agents are considered to be autonomous entities which contain intelligence that serves for solving their selfish or common problems, and to achieve certain goals. These agents constitute Multi-agent Systems (MAS). However, the autonomous, responsive, and proactive natures of agents make the development of agent-based software systems more complex than other software systems. Furthermore, the design and implementation of a MAS may become even more complex and difficult to implement when considering new requirements and interactions for new agent environments like the Semantic Web. Both domain-specific modeling and the use of a domain-specific modeling language (DSML) may provide the required abstraction, and hence support a more fruitful methodology for the development of MASs. Within this context, a DSML, called SEA_ML, has been developed for the design and implementation of MAS with including all of its components and supporting software tools in this project. In addition to the classical viewpoints of a MAS, the proposed DSML includes new viewpoints which specifically support the development of software agents working in the Semantic Web environment. At first, a metamodel and an abstract syntax were defined for SEA_ML. Later, both graphical and textual concrete syntaxes were developed. Upon completion of the formal definition of the semantics, operational semantics was derived via model transformations in order to provide the real implementation of the designed MAS models. Codes for the agent software can be automatically achieved as the result of applying model to code transformations. All required tools for MAS modeling and developing software according to SEA_ML were also constructed in this project.

Discovery of the most appropriate services meeting with the requirements of mobile device users is one of the crucial aims of service-oriented software systems. Although geographical closeness to the mobile user represents one of the important criteria on the determination of the services, such closeness is no more sufficient due to the diversity seen on both the requirements of the users and types of the services. Especially, improper assessment of service capability and quality causes those services to be inappropriate for the user needs despite of their geographical closeness. Research on the use of the Semantic Web and related technologies to cope with this problem recently became popular. If both the capabilities of the services and the requirements of the users can be modeled and defined according to some ontologies, matchmaking of the service capabilities and user requirements becomes more efficient and hence the suitable services will be discovered easily. Vast major of the work in the related research field covers noteworthy contributions for the semantic discovery in question. However, the performance of the proposed approaches especially on the real mobile platforms is an open issue. In order to fill this gap, performance measurement of the semantic discovery of the services, registered in various ontologies with different sizes, has been carried out in this project. Services of some eating places (e.g. cafes and restaurants), distributed over an area, are considered as the semantic services in the study. Discovery of these places according to both their geographical and semantic closeness to the mobile users has been tested inside a real implemented system.

![]() An example of listing eating places, which are matched with the user request in the same semantic closeness level. At this case, services are listed according to their geographic closeness to the mobile user. |
Elapsed time averages of semantic service discovery in different service ontologies with total individual numbers ranging from 100 to 20000. Each total elapsed time (given in msec) is the sum of 1) time required for sending mobile user's search request to the server, 2) service matching performed on the server and 3) listing results on the user's cellular phone
