Construction Maximum Lifetime Tree and Adaptation in Wireless Sensor Networks

Abstract

The maximum lifetime problem in wireless sensor network is important to monitor a set of interesting target locations and route the collected information to a central base station. In this paper, first, we consider the method of construction maximum lifetime tree taking into account general type of data aggregation, exchange of control messages and packet transmission loss. Second, we consider the method increasing lifetime of tree and reducing complexity and latency combining optimization of energy consumption in entire network through quasioptimization of local nodes and adapting. Experiment results show that the proposed method is more robust and valid than the previous method.

“…Fig 5 shows the results when M = 250 (similar results for other network sizes can be found in [10]). By combining reports from various sources, E-Span reduces a considerable amount of redundant traffic in the network.…”
