Performance Simulation of Multihop Routing Algorithms for Ad-Hoc Wireless Sensor Networks Using TOSSIM

The efficiency of the ad-hoc wireless sensor networks (WSNs) largely depend upon the routing algorithm employed. A large number of new routing protocols (table driven, demand driven and hybrid) have also been developed. This paper analyzes the performance of destination-sequenced distance-vector (DSDV) routing protocol (table driven) and the ad-hoc on-demand distance vector (AODV) routing protocol (demand driven) for mobile and stationary environments. The metrics - packet delivery ratio (PDR), end-to-end delay and routing overhead are measured by varying the number of nodes and the traffic load. TOSSIM is used for accurate simulation studies with 30 nodes in many-to-one routing configuration.
