EZ-SEP: Extended Z-SEP Routing Protocol with Hierarchical Clustering Approach for Wireless Heterogeneous Sensor Network

Wireless sensor networks (WSN) are of thousands nodes installed in a defined physical environment to sense and monitor its state condition. The viability such network is directly dependent limited by the power batteries supplying these networks, which represents disadvantage network. To improve extend life WSNs, scientists around world regularly develop various routing protocols that minimize optimize energy consumption nodes. This article, introduces new heterogeneous-aware protocol well known as Extended Z-SEP Routing Protocol with Hierarchical Clustering Approach for Heterogeneous Sensor Network or EZ-SEP, where connection base station (BS) done via hybrid method, i.e., certain amount communicate directly, while remaining ones form cluster transfer data. Parameters field unknown, partitioned into zones depending on node energy. We reviewed concerning election head (CH) communication BS presented novel extended mechanism selection CH based residual In addition, EZ-SEP weighted up using estimation schemes repositioning, altering density, variable comparison previous parent algorithm. was executed compared Z-SEP, SEP, LEACH. proposed algorithm performed MATLAB R2016b simulator. Simulation results show our version performs better than stability period due an increase number active 48%, efficiency high packet delivery coefficient 16% optimizes average 34.
