Extending Lifetime of Wireless Sensor Network Using Connected Dominating Set and Energy Harvester

Energy consumption in wireless sensor network is of paramount importance, which is demonstrated by large number of algorithms, techniques and protocols that have been developed to save energy and to extend lifetime. In WSN for mission critical application two performance metrics are: reliability and energy efficiency. In literature CDS based technique is used to achieve reliability. CDs allow communication between any arbitrary pair of nodes in the network. Poly is the topology construction protocol. It is based on the idea of a polygon. It achieves better connectivity under highly dynamic network topologies. Our simulation results demonstrate that IPoly performs consistently better in terms of message overhead, Energy overhead and reliability. We also model the reliability of Poly and compare with CDS-based techniques to show that it achieves better connectivity under highly dynamic network topologies.
