A Safe, Quick and Scalable Solution to Data Flow Transfer in Wide Area Network of Sensors

One of the challenges facing us in a wide area sensor network (WASN) is how to transfer real-time data produced by sensors quickly and safely to authentic users. In this paper, we propose a solution which is based on both sensor agent which is used to dividing WASN and random number ID encryption. By setting a sensor agent node, we group the sensors according to their geographical condition, and we also grant the agent node some administration privilege to manage the sensors. By selecting a random number for a sensor´s ID, we encrypt the data to be transferred. Experiment results shows that our approach is timesaving and has a better locating performance
