Abstract:

The problem of unbalanced energy consumption and transmission delay in Wireless Sensor Network (WSN) is studied, and a novel routing algorithm is proposed. By establishing the minimum hop count and protecting the remaining energy of the nodes, the algorithm makes packets traverse to Sink nodes through the paths with optimized energy. Simulation is carried out in MATLAB and it proves that the algorithm can balance energy consumption and increase the network lifetime.
