Mobile Ad hoc Network (MANETs) relies on cooperation of all participating nodes. All mobile nodes may easily vulnerable to selfish/malicious nodes which can lower down data communication and degrade the network performance due to refusal of relaying packet in order to save their own resources such as power, time, etc. These non-cooperative behaviors become challenging in cooperative caching sys...
Semantic caching is a technique used for optimizing the evaluation of database queries by caching results of old queries and using them when answering new queries. CoopSC is a cooperative database caching architecture, which extends the classic semantic caching approach by allowing clients to share their local caches in a cooperative matter. Thus, this approach decreases the response time of da...
This paper presents a novel approach to model-driven development of Digital Library (DL) systems. The overall idea is to allow Digital Library systems designers (e.g. information architects, librarians, domain experts) to easily design such systems by using a visual language. We designed a Domain Specific Visual Language for such a purpose and developed a framework supporting it; this framework...
This paper proposes a cooperative approach for composite ontology mapping. We first present an extended classification of automated ontology matching and propose an automatic composite solution for the matching problem based on cooperation. In our proposal, agents apply individual mapping algorithms and cooperate in order to change their individual results. We assume that the approaches are com...
A Cooperation Oriented Action (CO action) is a modelling abstraction for representing collaborative behaviour between objects at different phases of the software development. In this paper, the original definition of a cooperative object-oriented approach for software development is extended in order to include the description of exceptional behaviour. Unlike the traditional methods that usuall...
When robots perform teamwork in a shared workspace, they might be confronted with the risk of blocking each other’s ways, which will result in conflicts or interference among the robots. How to plan collision-free paths for all the robots is the major challenge issue in the multi-robot cooperative pathfinding problem, in which each robot has to navigate from its starting location to the destina...
When two or more self-interested agents put their plans to execution in the same environment, conflicts may arise as a consequence, for instance, of a common utilization of resources. In this case, an agent can postpone the execution of a particular action, if this punctually solves the conflict, or it can resort to execute a different plan if the agent’s payoff significantly diminishes due to ...
A general model for the coevolution of cooperating species is presented. This model is instantiated and tested in the domain of function optimization, and compared with a traditional GA-based function optimizer. The results are encouraging in two respects. They suggest ways in which the performance of GA and other EA-based optimizers can be improved, and they suggest a new approach to evolving ...
This paper investigates design issues which support awareness in collaborative environments. The work we present is part of the POLITeam project, an ongoing research effort aimed at the development of electronic tools to support the cooperation of German government sites distributed between Bonn and Berlin. The paper addresses social, ethical, legal, and technical issues which form important pr...
A novel Cooperative Bee Swarm Optimization (CBSO) algorithm based on foraging behaviour of honey bees is presented. The CBSO employs cooperative behaviours of multiple swarms in optimizing numerical functions. The proposed approach provides different patterns which are used by the bees to adjust their flying trajectories. The flying patterns provide an efficient way to balance exploration and e...
