Energy Efficiency in Dynamic Cluster Selection for Cooperative Wireless Sensor Networks

Previous work on energy efficiency in Wireless Sensor Networks (WSN) focuses on one-dimension topology in cluster selection strategy. Here we extend it into two-dimension model by including the effect of angle of elevation in the energy modeling and examine the contribution from the sensor mobility in the cooperative WSN. Then, we propose a general framework for energy-efficient routing based on dynamic cluster selection strategy to achieve further improvement. Through numerical analysis, we demonstrate that the proposed model achieves better energy efficiency against the single hop communication.
