An Entropy-Based Multipath AODV Routing Protocol in Ad Hoc Networks

A Mobile Ad Hoc Network (MANET) is a dynamic wireless network that can be formed without the need for any pre-existing infrastructure in which each node can act as a router. Providing high quality communications service among mobile wireless devices is basically a challenging task in wireless ad hoc networks. This paper proposes a multipath routing protocol called entropy-based multipath AODV (EM-AODV). Compared to the conventional multipath extension on AODV (AODVM), EM-AODV assigns the construction of multiple paths to the destination node and makes it algorithmically simple, resulting in the improved performance of packet delivery and average end-to-end delay incurred at intermediate nodes. Simulations demonstrate the performance benefits of our proposal EM-AODV over AODVM and AODV in most movement scenarios.
