Communication of mobile robots in temporary disconnected manet

Abstract

Mobile ad – hoc network (MANET) provides the new possibilities of multihop communication between mobile terminals without any fixed infrastructure. All mobile nodes are communicating with each other via wireless links and the topology of the network may change unpredictably. The MANET can be used not only for disaster events but can be used for robotic communication. The main problems of the all MANET routing protocols occur if the communication paths between mobile terminals are disconnected. In this paper we focused on the problem of temporary disconnections of the communication links. We propose the enhancement of the reactive routing protocol, also known as dynamic source routing protocol (DSR). Our enhancement provides possibilities to use opportunistic routing of the messages in the case that the routing protocol cannot find communication paths. In this case the routing protocols for MANET stop the routing process and wait for connection, and our modification provides the possibilities to send messages to mobile nodes if the routing protocols are stopped.
