An Improved Distributed Energy-Conserving Routing Algorithm for Sensor Networks

The paper introduces an improved distributed minimal power routing algorithm for sensor networks. Using the greedy method which is different from the one in [1], our algorithm has a trade-off between minimizing the total power consumption (which may drain critical nodes) and maximizing the minimal residual power of the network (which may use too much total power), and therefore maximizes the lifetime of the whole system .
