Maximized lifetime model and its solution of layer-based sensor networks
Jingguo Dai · Journal of Computer Applications · 2009
On the basis of rectangular deployment field,the authors proposed a layer-based model to maximize the lifetime of sensor networks which met the connectivity coverage constraints,and a non-uniform node deployment algorithm for sensor networks.The width of the layer was decided by node energy consumption.Also,the number of nodes in every layer was determined.Simulation results show that layer-based non-uniform node deployment algorithm can effectively extend the lifetime of the sensor networks.
