Enhanced NN based RZ leach using hybrid ACO/PSO based routing for WSNs
Deepshikha Deepshikha, Priyanka Arora, Varsha Varsha · 2017
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. 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 Neural Network (i.e. in the selection process of cluster heads) and Hybrid ACO/PSO technique (finds the shortest route) in optimizing the network lifetime and to improve energy efficiency. While comparing the performance of RZ LEACH, ACO RZ LEACH with the proposed system, result shows that proposed technique helps to increase the energy efficiency, thus prolongs network lifetime.
