Multi-priority and trusted multi-path selection algorithm for ad-hoc network

This paper presents a multi-priority and multi-path selection algorithm for heterogeneous traffic for wireless ad-hoc networks. The main objectives are achieving higher throughput, better resource utilization through load balancing and relinquish network congestion. The proposed algorithm has considered signal-to-interference plus noise ratio (SINR), available link bandwidth, link delay (transmission delay and queuing delay), trust value of a node and traffic class (such as real time and non-real time traffic) to select optimal path. The performance of the proposed Multi-Priority and Trusted Multi-Path Selection (MTMS) algorithm has been evaluated by OPNET Modeler 14.5 simulator. It is found that in terms of average throughput (bit/second) and link delay proposed MTMS algorithm outperforms ad-hoc on-demand distant vector (AODV) and dynamic source routing (DSR).
