The optimum configuration of car parking guide system based on wireless sensor network

When wireless sensor network (WSN) based on ad hoc network is deployed to car parking guide system without parking helper at area or building with large scale of parking lots, the optimum number of cluster heads was derived for getting the minimum power consumption as well as time delay. Through the theoretical analysis of power consumption and time delay with the number of cluster heads in wireless sensor network, it was found that there exists the minimum point in the variation of power consumption and time delay according to the number of cluster heads.
