A tactic Agent middleware in Wireless Sensor Networks based on associative monitoring scheme

The management of Wireless Sensor Networks (WSN) is to maintain the communication resources and effectively control sensing data, considering the energy of nodes and dynamic topology. A tactic-oriented initiative management system based on Mobile Agent was proposed, which can use the tactic agent to control layered networking and realize the distributed processing of managing tasks by mobile agent. A local tactic library was established to enhance the adaptive capacity of topology management, through exploiting the data monitoring mechanism based on data aggregation to implement stratified scanning and tactic managing on data. Simulation results show that this system can effectively save the energy of nodes and reduce the consumption for communication, and also lengthen the survival time of networks.
