A mobility aware Modified AODV for heterogeneous mobile ad hoc networks.

Heterogeneous Mobile Ad-hoc Networks (MANETs) are composed of nodes with different transmission range. Due to the difference of transmission range and relative velocity for network nodes, the link between two nodes can or will be unidirectional. In the standard AODV protocol, the shortest path is always selected. But this shortest path is the easiest broken one. In this paper, we propose an improvement of AODV protocol called H-MAODV(heterogeneity and Mobility aware AODV). This protocol is based on considering the distance and relative velocity between each node and one hop neighbor. Which permits to avoid losing route. Through the simulation, it is confirmed that this improvement has higher package delivery fraction than basic AODV protocol. [ABSTRACT FROM PUBLISHER]
