A context-aware and group-based service discovery in mobile ad hoc networks

Nowadays dynamic networks have been growing and have made mobile ad hoc network (MANET). One of the most important tasks in mobile and dynamic environments is service discovery, i.e. how a client can use his service of interest. Context information that show status of entity, play important roles for service discovery. In this paper, we propose a context aware and group based service discovery solution using context sources in the form of an advertisement board for services. Using group information lead to intelligent routing request, increase speed of discovery, and decrease number of exchange packets. To evaluate the solution a simulation tools has been developed and the results indicate that using context sources, our proposed approach has acceptable number of exchanged packets and good performance.
