Load balancing with multipath routing in MANETs

Abstract

Mobile ad hoc network is a collection of wireless mobile nodes, such devices as PDAs, mobile phones, laptops etc. that are connected over a wireless medium. There is no pre-existing communication infrastructure (no access points, no base stations) and the nodes can freely move and self-organize into a network topology. Hence, balancing the load in a MANET is important because the nodes in MANET have limited communication resources such as bandwidth, buffer space, and battery power. Most current routing protocols for mobile Ad-hoc networks consider the shortest path with minimum hop count as optimal route without any consideration of any particular node’s traffic and thus degrading the performance by causing serious problems in mobile node like congestion, power depletion and queuing delay. Therefore it is very attractive to investigate Routing protocols which use a Routing Metric to Balance Load in Ad-hoc networks. This paper discusses about LBMPR (Load balancing with multipath routing protocol) for efficient data transmission in MANETs.
