The different factors affecting an efficiency of a sensor network and the different algorithms which improve the efficiency of a wireless sensor networks, with a four different solutions for optimal energy utilization in a wireless sensor networks over some of the existing clustering protocol are the main topics of deliberations and output of this book Different Novel methods of selecting a cluster head for increasing the lifetime of a sensor network are presented and discussed. The novel methods illustrated in this book are First: the based on residual energy, Second: based on number of cluster head, initial energy and with two more factor for increasing the lifetime of a network Third: a new solution for resolving efficient utilization of energy in energy heterogeneity sensor network Fourth: Importance of tier structure for a sparse sensor networks Это и многое другое вы найдете в книге Optimal Energy Utilization in Sensor Networks by Clustering
