Abstract

A hybrid routing protocol for mobile ad hoc networks (MANETs) called improved ad hoc on-demand distance vector (IAODV) is proposed in this paper. It merges the AODV routing protocol with multipath and path accumulation (PA). The performance of IAODV is compared with AODV by OPNET simulations. The results show that a significant reduction in delay and improvement in packet delivery ratio are achieved. It also reduces the routing overhead by reducing the frequency of route discovery process.
