Energy Efficient Wireless Sensor Networks based on QoS Enhanced Base Station controlled Dynamic Clustering Protocol

Recent development in Micro Electro Mechanical System (MEMS) technology leads to the development of low cost and low power utilizing wireless micro sensor nodes. Wireless sensor network is a power consuming scheme, because nodes executes on restricted power batteries which reduces its lifetime. Extending the network lifetime is based on the better managing of sensing node energy resource. Energy efficient routing protocol is very essential technique in wireless sensor networks because sensor nodes are extremely energy based. As a result, several researchers have provided different routing protocol for sensor networks, particularly routing protocols depending on clusters protocols. This is because the usage of cluster based routing has several merits like minimized control messages, re-usability of bandwidth and enhanced power control. Different cluster based routing protocol is proposed by many researchers for the purpose of reducing the consumption energy in wireless sensor networks. Those technique reduces the energy consumption but with several disadvantages like lack of QoS, inefficient transmission, etc., To overcome those problems, modified QoS enhanced base station controlled dynamic clustering protocol for wireless sensor networks is proposed in this paper. Simulation results show the better energy consumption is achieved by the proposed protocol when compared to the conventional techniques. Index terms Wireless Sensor Network, Clustering protocol, QoS
