The research of mobile route positioning security based on wireless sensor network

As for the limitation to the power, calculation performance and communication performance of wireless sensor network, according to the object that decreases the energy cost and propones the life cycle of network, on the basis of the advantage on mobile agent technology, a new positioning algorithm of wireless sensor route is proposed with the combination ant colony algorithm and mobile agent technology. At first the algorithm adopts nodes movement estimatxed algorithm and judges the possible subnets to which the mobile node transfers in advance; then reserve resources in subnet in advance, and judge the possible subnet to which the mobile nodes add according to the movement direction; finally the optimized route is acquired by adopting improved ant colony algorithm seeking system. In this way not only the limited bandwidth and power of wireless sensor network could be saved, but the issue that it is difficult to provide QoS security due to subnet switch could be solved. The simulation test indicates the proposed method could improve the resource utility for sensor network, decrease redundant data transfer efficiently, decrease communication consumption and propone the life cycle of network.
