An Energy-Efficient Ring Cross-Layer Optimization Algorithm for Wireless Sensor Networks

In wireless sensor networks, cross-layer optimization is a hot topic. In order to balance energy consumption a clustering based cross-layer optimization model is established in this paper. In this model, the network layer could get the related information from physical layer and the datalink layer to effectively route packets. Based on the cross-layer optimization model, an energy-efficient ring cross-layer optimization algorithm is proposed and a new routing algorithm called Leach-Cross-Layer Optimization (CLO) is also proposed for a ring monitoring domain. This Leach-CLO routing algorithm is based on the typical Leach algorithm. The experiment results show that this routing algorithm could effectively and efficiently balance the energy consumption in wireless sensor networks compared with related algorithms.
