摘要：This work is to build an energy efficient and power aware technique so as to prolong the wireless sensor network lifetime. In the development of various large-scale sensor systems, a particularly challenging problem is how to dynamically organize the sensors into a wireless communication network and route sensed information from the field sensors to a remote base station. A new energy-efficient dynamic clustering technique for large-scale sensor networks is proposed. By monitoring the received signal power from its neighboring nodes, each node estimates the number of active nodes in real time and computes its optimal probability of becoming a cluster head, so that the amount of energy spent in both intra and intercluster communications can be minimized.
