Efficient Stochastic Dijkstra Protocol For Mobile Ad-Hoc Network With Quality of Service

Abstract

Mobile Ad Hoc Networks (MANET) consists of a group of mobile nodes, which autonomously establish connectivity via multi – hop wireless communications. This Paper present a new protocol model, a stochastic Dijkstra Routing (SDR), for MANET. To effectively route the traffic for ever changing nodes in MANET with a constrains of less overhead and best quality end to end packet delivery ratio, a novel approach SDR will be presented which involves the technique of evenly or equally distribution of traffic through random variable for a link metrics to provide sort of load balancing. In MANET, SDR protocol shows good agreement for above mention constrains compares to AODV (Ad hoc On demand Distance Vector) routing protocols. Simulation study compared SDR with AODV and the result show that SDR is able to achieve better or comparable results at lower load and better results at higher traffic loads as compared to AODV. In addition, SDR achieves this performance with better delay and improved traffic characteristics along with significantly lower consumption of MAC layer resources and remain consistence in the confidence interval. So, the proposed SDR scheme in this paper promises for QoS (Quality of service) in MANET.
