Performance improvement of dynamic source routing protocol for multimedia services in mobile ad hoc network

All mobile nodes participating in a group communicate with one another in the group through a shared radio link without cable or backbone composes an infrastructureless network, called mobile ad hoc network (MANET). Because network topology may be changed at any time as result of mobility of nodes and the failure of available routes, quality-of-service (QoS) of real-time multimedia application may have difficulty in satisfying their services. In this paper, we propose a routing scheme for multimedia services called modified dynamic source routing (MDSR) protocol. The MDSR selects the shortest path by using power level. Our proposed scheme provides lower average delay and mean number of hop path from source to destination than DSR protocol can provide.
