The Research Of WSN Energy Efficiency Based On Mobile Agent

With the rapid development and increasingly sophisticated of communication, embedded computing and sensor technology, with a perception by the substantial capacity, computing power and communications capability of, Sensor networks composed of thousands of micro-sensors, with each senor capable of sensing ,computing and communication, has aroused great concern. It integrates the sensor, embedded computing, networking, and wireless communications technology, become a new information acquisition and processing technology, is widely used in national defense and military, environmental monitoring, traffic management, medicine and health care.Agent technology is developed from artificial intelligence. Agent system is a loosely coordinated system which stands for the trends of distributed software development, is more flexible and intelligent. Agent software as a new software technology has made considerable progress, is used in many areas such as internet information retrieval, information collection, e-commerce, data mining, integrated manufacturing and so on.The node of the wireless sensor network often uses batteries to supply electricity, but the electricity energy in the batteries is limited, meanwhile the communication, calculation and storage abilities of the node are limited which raise challenges to the hardware and software design of the wireless sensor network. This dissertation, basing on this background , sums up research achievements of wireless sensor networks, proposes a WSN management model which combined hierarchical architecture with Mobile Agent , designs WSN topology management algorithms and data collection algorithms based on mobile Agent. and last, combined with the energy model those algorithms are simulated, the results show that the topology management and data collection algorithm based on mobile Agent are more energy-efficient in Guaranteeing quality of service.
