Energy Efficient Node Clustering in Wireless Sensor Networks
Computer Engineering Department
Wireless Sensor Network consists of spatially distributed and energ-constrained autonomous devices using sensors to cooperatively monitor physical or environmental conditions such as temperature, sound, vibration, pressure or pollutants, at different locations. Because of sensors limited energy supply, energy efficiency is a critical design issue in sensor networks. In order to minimize energy consumption and extend network life-time, grouping sensor nodes into clusters is a widely pursued approach. Having a good cluster head selection and cluster formation, substantial level of gain can be gathered in energy consumption of sensor networks. In addition to this common objective, different clustering protocols try to achieve different design objectives determined by type of applications and design assumptions taken into account.
