| Abstract: | This paper investigates how to determine the active nodes in wireless sensor networks (WSNs) and the optimal transmission ranges for each active routing nodes in order to save the energy consumption. Three algorithms are presented and the relation between the optimal transmission ranges and the communication traffic is obtained in a simple linear network with the candidate route nodes randomly deployed. Numerical results show the dynamic programming algorithm can select the optimal route nodes and their transmission range and is more efficient than the other two algorithms. |
