Abstract

In wireless communication power feeding is essential problem. The nodes contributing in the network are powered by limited battery resources and the battery reduction can imply network failure. While establishing exact and capable paths is an main proposal problem in MANET. The problem of network exhausting batteries which dividers the entire network can be banned by considering the energy consumption in MANET. Energy-aware multicast communication in mobile ad hoc networks (MANET) is a vital issue due to the power constraint of battery in each mobile node. In this paper, proposed an energy efficient multicast routing problem for MANET that catches a path for each node-pair connecting the source node and the destination set such that any node in each path does not run out of its power during the transmission of packets. The problem of multicast routing is NP-complete. This problem resolved by Genetic Algorithm mechanism. It presents an improved solution for the multi-constrained multicast routing problem. The computational power of the proposed GA-based multicast routing is demonstrated through simulations.

Abstract

In mobile ad hoc network, nodes co-operatively form a network independent of any fixed base station infrastructure. Every node in a mobile ad-hoc network can function as a router and forwards the data packets to the other nodes. Multicasting plays an important role whenever group communications are required. Most of the existing multicast routing protocols in mobile ad hoc networks consider only one source in a multicast group and become inefficient when the protocol is extended to multi-source multicasting. In this paper, we propose a unicast forwarded multi-source multicast routing protocol, for ad hoc networks which is having more than one source in a group. Here, the sources of the group also act as a receiver for other sources in that group. The proposed routing method is a cluster based one and avoids the flooding or broadcasting of control packets to form routing structure. On executing source joining and receiver joining procedures, a complete path for multicast data transfer was established. As the join request control packets are forwarded only through cluster-heads and junction nodes, lower amount of control overhead is incurred. Simulation result shows that the proposed protocol maintains the delivery ratio with reduced control overhead and utilizes the bandwidth efficiently.
