Abstract

The Gossip-Based Relay Protocol (GRP) is developed based on Ad Hoc on Demand Distance Vector Protocol (AODV) and proposed to increase the efficiency of package routing functionality in ad hoc networks through specific flooding scheme. This lightweight protocol reduced the collisions on the network through specific mechanisms. Request to Send/Clear to Send (RTS/CTS) mechanism is widely used in ad hoc environment with Temporarily Ordered Routing Algorithm (TORA) in order to eliminate collisions and allow access to the shared medium through proposed authentication methods. Since GRP contains specific mechanism of directed acyclic Graph (DAG) mechanism to mitigate overhead problem, RTS/CTS modified TORA might result in similar performance metrics. In this paper, TORA protocol has a modification of new RTS/CTS mechanism and has been simulated in order to be compared with proposed lightweight robust forwarding GRP scheme in terms of specific performance metrics such as network throughput, end-to-end delay and message flooding rate over the network through OPNET simulation package in order to expose the optimal solution to increase overall network throughput in ad hoc environment.
