Abstract

Energy efficiency is an important technology of sensor networks development. In this paper we offer a method of sensors lifetime maximizing under required level of network reliability. The optimizing statement is offered. As example, we consider homogeneous sensor networks with topology like tree. Other example concerns ZigBee technology. It shown that heterogeneous network can be improved by power elements reassignments. If a sensor network topology is fixed then the most critical nodes can be detected and improved.
