- W96633209 abstract "Abstract —The problem of routing in mobile ad hocnetworks is considered as an important issue. In fact,these networks are characterized by multi hop wirelessconnectivity, node mobility, limited power and memoryresources. In this paper we study several possible modi-fications of AODV[1] routing protocol based on selectedfeatures available in other routing protocols. Simulationresults allowed us to select the two most relevant ones.MMDV is an amelioration of AODV protocol providingfor multipath and MPR based flooding. This protocolconsists of both proactive and reactive components. Ina proactive phase, nodes compute their MPR lists andcompute paths to their two hop neighbors. In a reactivephase, nodes compute two paths for each destination.Simulation results show that MMDV enhance the packetdelivery performance and reduce the overhead. Keywords: ad hoc, routing protocols, node mobility,AODV.I. I NTRODUCTION A mobile ad hoc network is a multi-hop wirelessnetwork without any infrastructure. Ad hoc networks arecharacterized by frequent changes and mobile nodes mayjoin the network, disconnect or move at any time. Theseproblems make the routing problem in ad hoc networksmore difficult than traditional wired networks.In this paper we study several possible modificationsof AODV[1] routing protocol based on selected featuresavailable in other routing protocols. Simulation resultsallowed us to select the two most relevant ones. More-over, we propose their combination called Multipath andMPR based AODV (MMDV).The rest of this paper is organized as follows: In thesecond section, we present routing protocols in ad hocnetworks. In the third section, we briefly review theAODV protocol and present related works which attemptto improve AODV. Section four describes specificationand design of our variants. In section five, we presentthe simulation results followed by their interpretations.Finally, we describe MMDV and analyze its simulationresults.II. R" @default.
