Performance Evaluation of Mobility Models on MANET Routing Protocols

With the advancement of wireless technology, portable devices that are capable of wireless communication have become extremely popular making possible the establishment of wide ubiquitous networks. Mobile Ad Hoc networks (MANETs) are wireless networks where the exchange of messages between the nodes does not rely on any pre-deployed infrastructure. This architecture, nevertheless, suffers from a highly unstable topology as the links between the nodes break constantly due to movement of the users. Path routing and protocol selection are the key strategies behind the design of any wireless network. In this paper we study and evaluate the effect of mobility on the routing protocols viz. AODV, DSDV, DSR and OLSR in terms of packet delivery ratio, average end-to-end delay and normalized routing load.
