DLBMRP: Design of Load Balanced Multicast Routing Protocol for Wireless Mobile Ad-hoc Network

Abstract

A mobile ad-hoc network (MANETs) is a wireless network of mobile nodes without any fixed base-station or any centralized administration. When a node sends a data packet to more than one node at a time, it is called multicasting, multicast often used to utilize the network resources like channel bandwidth and node energy to improve the network efficiency. Multicast in MANETs have several challenges due to frequent changes in the network such as node mobility, reliability, limited resources, etc. The MANETs is widely used in several fields like emergency searches, rescues operation, and military battlefields where sharing of information is mandatory. These operations often require a rapid deployable and quick reconfigurable routing protocols. Since mobile nodes in wireless ad-hoc network have limited resources so an efficient multicast routing protocol is needed to reduce the wastage of resources. This paper proposes a traffic load balanced multicast routing protocol (LBMRP) in order to reduce the network overhead and increases the network life. In this scheme all mobile nodes are randomly classified into multi group (three groups) and create a tree for each group in order to achieve efficient data transmission. Simulation results shows that the proposed LBMRP scheme outperforms with some existing multicast routing protocols as multicast ad-hoc on-demand distance vector routing protocol, reliability of the multicast ad-hoc on demand distance vector and Parallel multiple nearly-disjoint trees multicast routing schemes.
