Position Based Opportunistic Routing Protocols for Highly Dynamic Mobile Ad-Hoc Networks

摘要

Communications in Mobile Ad Hoc Networks in emergency situations play an important role. In such network reliability of packet delivery is indispensable as the information exchange accuracy has to be guaranteed. At the same time information has to be reached to the intended node in timely fashion. The existing solutions are vulnerable to node mobility. To overcome this problem, of late, Positionbased Opportunistic Routing (POR) protocol was introduced by Yang et al. which makes use of geographic routing wireless medium. When data packets are sent through network some node overhear. One of the nodes that overhear the packet will act as forwarding node. Thus the protocol ensures reliable communication in MANET. In this paper we implement the scheme proposed by Yang et al. Our prototype application, a custom simulator, demonstrates the proof of concept. The empirical results revealed that the prototype is useful for further research and improvement in MANET communications.
