OPTIMIZING LEACH USING HYBRID ACO/PSO FOR MOBILE SINK IN WSNs: A REVIEW

Abstract

WSN consist of base station called sink and battery enabled sensor nodes. The energy of sensors is used to transmit data to the base station and it reduces with time. The energy consumption can also be reduced by using the idea of mobile sink which communicate between end user and sensor nodes. Later on concept of rendezvous nodes (RZ) and mobile sink was combined with LEACH to reduce energy consumption. In order to contribute more toward this direction Ant Colony Optimization (ACO) has been added to find the optimized route. The proposed work uses the concept of Hybrid ACO/PSO technique (finds the shortest route) have been used in optimizing the network lifetime and to improve energy efficiency.
