Using hybrid ACO/PSO enhance NN RZ leach for mobile sink in WSN's

Wireless Sensor Networks (WSNs) are getting popular day by day. But due to the constrained of resources and limited battery supply of sensor nodes, this becomes the major areas of research. Earlier the LEACH protocol proposed contributes a lot in terms of reducing energy consumption among sensor nodes. Later on concept of rendezvous nodes (RZ) and mobile sink was combined with LEACH to reduce energy consumption and to prolong lifetime of network. In order to contribute more toward this direction Ant Colony Optimization (ACO) has been added to find the optimized route. The proposed work makes use of the concept of Neural Network (in the selection process of cluster heads) and Hybrid ACO/PSO technique (to find the shortest route) has been used in optimizing the network lifetime and to improve energy efficiency. While comparing the performance of RZ LEACH, ACO RZ LEACH with the proposed system, results shows that the proposed technique increase the energy efficiency, thus prolongs network lifetime.
