Abstract

A mobile ad-hoc network (MANET) tries to solve the problem if the infrastructure is not available or inconvenient for its use such as in rural environments, trucks, cars or in battlefield. Mobile ad-hoc network consists of autonomous mobiles devices (nodes) that can also serve as router and can dynamically move around arbitrarily at appropriate speed in any direction resulting in an ever-changing topology of nodes. Real-time applications in MANET demand real-time forwarding which means messages in the network are delivered according to their end-to-end deadlines (packet lifetime). This paper proposes a novel real-time routing protocol that ensures high packet throughput with minimized packet overhead and prolongs the lifetime of MANET. Moreover, the proposed mechanism utilizes an optimal forwarding (OF) decision that takes into account of the link quality, packet delay and the remaining power of next hop nodes. The performance of proposed routing protocol has been successfully studied and verified through the simulation work based on IEEE 802.11b. The simulation results show that the proposed routing protocol possesses short average delay. Hence, it can be used for real-time routing.
