Abstract |
A MANET is a set of mobile nodes that are free to move dynamically and unpredictable in environment, but this dynamic nature of the network topology cause for many challenges in MANET. Multicasting is one of methods that because of group-oriented computing are mostly used in MANET routing. Protocols have designed for multicasting in MANETs that ODMRP is one of them. ODMRP is on-demand and mesh based protocol that delivers packets from source to destination by building a mesh. PDR is most important metric that we should consider in packet forwarding. It may affects by different criteria such as packet size, group size, action range and mobility of nodes. ODMRP uses single path to forwarding packets and this cause to PDR reduction in destination. The proposed method in this article uses multi coded paths technique. Thus due to route diversity and overcoming single route breakage, our approach can improve PDR from source to destination. |
