A New On-demand Aouting Algorithm Based on Nodes Locations for MANET
Min Lou · 2008
Mobile Ad-Hoc network (MANET) is a dynamic and autonomous network composed of wireless mobile hosts or nodes.It is significant to implement an on-demand routing protocol with bandwidth assurance in MANET.This paper presents a new on-demand routing algorithm LABGR (Location-aided bandwidth guaranteed routing),which is based on physical locations of the nodes.The algorithm integrates the route stability and nodes’ limited energy,and by using constrained diffusing routing,utilizes multiple mechanisms to avoid flooding in whole network,and limits the number of nodes affected during routing request.Thus,the algorithm efficiently increases the efficiency of routing request and guarantees the bandwidth of links.Finally,the paper analyzes the characteristics of LABGR.
