Abstract:

Unidirectional links have impacts on the routing maintenance mechanism of origin multicast Ad hoc on-demand distance vector (MAODV) protocol. In order to enhance the real-time performance and completeness of communication, this article put forward an improved routing protocol MAODV-UNI for unidirectional links. It can improve the routing efficiency by detecting the unidirectional links timely during the route maintenance and reasonably use it. Then use NS2 to simulate MAODV-UNI and compare with the original MAODV protocol in the same scene with unidirectional links. It is proven that MAODV-UNI has advantages about packet delivery rate and delay that make it more effective compare with original MAODV.

Key words: mobile Ad hoc networks, unidirectional link, multicast Ad hoc on-demand distance vector protocol
