A Comprehensive Study and Review on Wireless Sensor Networks, Based on Heterogeneous Energy Distribution & Multizone Algorithm

Abstract: Wireless Sensor Networks(WSNs) is built of �nodes� �from a few to several hundreds or even thousands where each node is node is connected to one ( or sometimes several ) sensors. Sensors nodes having limited power resource which describe sensed data to the base station that requires high energy usage. There are several routing protocols have been proposed in recent years, achieving energy efficiency in heterogeneous scenarios. Still, every protocol is not desirable for heterogeneous wireless sensor networks (WSNs) .In this paper there are algorithms- Distributed energy efficient clustering (DEEC), Developed distributed energy efficient clustering (DDEEC), Enhanced distributed energy efficient clustering (EDEEC) and Threshold distributed energy efficient clustering (TDEEC) which is designed for heterogeneous wireless sensor Networks. In this paper we first discuss performance of heterogeneous wireless sensor networks, which is prolonging the lifetime and stability of the network and throughput .we compare performance of DEEC, DDEC, EDEEC, and TDEEC, for different scenarios of three and multilevel heterogeneous wireless sensor networks.
