Swarm Intelligence based Energy Efficient Routing Protocol for Wireless Ad-hoc Networks

Mobile Ad Hoc Networks are communication networks built up of a collection of mobile devices which can communicate through wireless connections. Mobile Ad-hoc network (MANET) has emerged as the self organized wireless interconnection for the various applications in random topology. However, achieving reliable multicast transmission in MANET is crucial due to the change in network topology caused by the node mobility. Wireless Networks are characterized by having specific requirements such as limited energy availability and reduced processing power. In this paper deals with the inability of the network to recover in case of failure networks, to reduce the maintenance overhead, increase the path stability, reducing the congestion in Mobile Ad-hoc network and with the inability of the network to recover in case of power problem in wireless network . Ant based routing protocols can add a significant contribution to assist in the maximisation of the network life-time, but this is only possible by means of an adaptable and balanced algorithm that takes into account the Wireless Sensor networks main restrictions.We are introducing a new concept of two ants, one acting as load agent and another as strategy agent to ensure better performance. The strategy agent is software acting as a processor which controls and guide the load agents as forward ants and backward ants.We are using a Backpressure technique for network activities as link failure and restoration of link information. We carry out these simulation results using NS 2.34. Keyword: MANET, congestion, energy, QoS
