Design of Energy Efficient Hierarchical Routing Protocol using ACO for WSN

Wireless sensor network have the some special characteristics such as limited energy, power consumption for processing and low energy. Energy is important criteria because battery has not rechargeable in sensors. In large scale network deployment sensor consume more energy to process data, it leads the lifetime of network will goes down. In this paper we propose the Energy Efficient Hierarchical Routing Protocol using ACO to improve the network lifetime and performance. Initially clusters are formed among the nodes based on node residual energy, node degree and distance. The ACO algorithm is applied to search optimal path, then data transmit via selected optimal path. To solve combinatorial optimization problems the ACO algorithm is used as it is based on heuristic algorithm. Distributed computing, self organization and positive feedback are the characteristics of ACO algorithm which is suited for searching routing in modern communication networks. In this paper we are going to propose intelligent EEHRPs based on ACO for wireless sensor network using NS2
