An Energy Efficient Hierarchical Heterogeneous Wireless Sensor Network

Future communication networks are expected to be heterogeneous consisting of different wireless systems such as WLAN and Bluetooth systems, which can be used in building wireless sensor networks. The development of these network technologies and due to the limited energy supply of sensors have prompted sensor researchers to consider alternatives that minimize energy consumption in sensor networks. For this reason, energyefficient protocols and algorithms for sensor networks have been recently proposed in the literature. In this document we investigate the problem of optimizing energy consumption in wireless sensor network. We propose a hierarchal wireless sensor network architecture consisting of two wireless technologies. A game theoretic approach to model energy constraints is explained. A detailed analysis of the wireless sensor network model will be presented.
