Threshold sensitive energy efficient multi-sink routing protocol for heterogeneous wireless sensor networks
(G.B. Pant University of Agriculture and Technology, Pantnagar - 263145 (Uttarakhand), 2017-08) Sumit Kumar; Mishra, P. K.
The prominence of Wireless Sensor Networks (WSN) has expanded massively in late time because of development in Micro-Electro-Mechanical Systems (MEMS) innovation. WSN has the possibility to associate the physical world with the virtual world by framing a system of sensor nodes. Here, sensor nodes are typically battery-driven gadgets, and consequently energy consumption of sensor nodes is a noteworthy design issue. This thesis addresses ‘WSN’s lifetime and stability period optimization problem” which is to design an energy efficient protocol in such a way that energy consumption of every node in the wireless sensor networks is minimized which results in an improved stability period and prolonged lifetime of WSNs. This thesis solves the problem by introducing a static clustering based multi-sink routing protocol for heterogeneous wireless sensor networks. The idea of threshold aware transmission is also utilized to accomplish these objectives. The results are compared with two well known traditional clustering protocols namely LEACH and SEP using stability period, network lifetime, instability period and throughput as performance metrics. The proposed work performs better than the other protocols under consideration.
