Performance Analysis of MANET Routing Protocols in Different Mobility Models

Vol. 9  No. 2  pp. 22-29


Ad Hoc Networks are multi - hop wireless networks with dynamically changing network connectivity owing to mobility. The protocol suite includes several routing protocols specifi-cally designed for ad-hoc routing. The conventional routing protocols such as shortest-path routing algorithms are not particularly well suited for operation in ad-hoc networking environment. The most widely used ad hoc routing pro-tocols are Ad-hoc On-Demand Distance Vector Routing (AODV), Destination Sequenced Distance Vector (DSDV), Dynamic Source Routing (DSR) and Temporally - Ordered Routing Algorithm (TORA). In this paper, the three random based mobility models such as Random waypoint, Random walk and Random Directions were implemented. The two different parameter constraints like packet-delivery fraction and End-to-end packet delivery delay are compared with respect to mobility speed, Traffic and Network size. The simulation results shows that the AODV protocols in Random Waypoint mobility model performs better than DSDV, TORA and DSR in Random walk and random Direction mobility model. . Based on the observations, it is to suggest that AODV routing protocol can be used under high mobility since it outperforms DSDV, TORA and DSR protocols.
