Increasing Lifetime of Wireless Sensor Networks by Changing Active & Sleep Mode
A model to identify the lifetime of target tracking wireless sensor network is proposed. The model is a static cluster-based architecture and aims to provide two factors. First, it is to increase the lifetime of target tracking wireless sensor network. Secondly, it is to enable good localization result with low energy consumption for each sensor in the network. The model consists of heterogeneous sensors and each sensing member node in a cluster uses two operation modes - active mode and sleep mode. The performance results illustrate that the proposed architecture consumes less energy and increases lifetime than centralized and dynamic clustering architectures, for target tracking sensor network.
