Sleep & Wakeup Technique Based Clustering Protocol-performance Evaluation in Wireless Sensor Network

In order to achieve data information, the Sensor Node’s should form into small groups as clusters in wireless sensor network. In Multi-hop sensor network, the Base-Station (sink) is might not be considered. That is why, the hot-spot problem may occur in this network. In this paper, we analyze the sleep & wakeup approach, in order to avoid the hot spot (WLAN) problem, which aims to increase the network lifetime using energy conservation as well as increasing packet delivery ratio (PDR). In this technique, C-H (cluster-head) has been selected based on energy level & Base-Station distance. Using this technique, we can improve the energy conservation & PDR up to 63%, when compare to that of FCA (fuzzy clustering algorithm) according to their parameters of FND (First Node Dead) and HNA (Half of the Node Alive) parameter for each algorithm. Our simulation results shows that the sleep & wakeup approach is better and energy efficient clustering protocol based on their parameters.
