Ad hoc on-demand distance vector multipath routing protocol with path selection entropy

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. Due to bandwidth constraint and dynamic topology of mobile ad hoc networks, multipath supported routing is a very important research issue. This paper proposes a Ad hoc On-demand Distance Vector Multipath Routing Protocol with Path Selection Entropy (AODVM-PSE). Compared to the conventional multipath extension on AODV (AODVM), AODVM-PSE assigns the construction of multiple paths to the destination node and makes it algorithmically simple, resulting in the improved performance of packet delivery, average end-to-end delay and control packets ratio incurred at intermediate nodes. Simulations demonstrate the performance benefits of our proposal AODVM-PSE over AODVM in most movement scenarios.
