Evaluation function effectiveness in Wireless Sensor Network routing using A-star algorithm

Routing will serve to facilitate a number of sensors on the technology of Wireless Sensor Network (WSN) to identify the optimal path and manage energy consumption saving at the time of transmitting data. The optimal path can be identified by using one of the methods from the field of Artificial Intelligent that is path finding method. The method will provide an effective and efficient way to find the optimal path and overcome the problem of energy efficiency in WSN. The path search algorithm presented in this paper for WSN routing is A-star algorithm. The goal is to obtain optimal routing path with the calculation of an effective A-star evaluation function. The proposed method is to compare the variations of the evaluation function based on heuristic value so that the effect of the variations on the results of path searching can be notified. The result of the simulations is that there are improving results achieved when the effectiveness of the evaluation function is also enhanced. Improving results can be identified from the more optimal path obtained.
