Abstract:Recent developments in the field of transmission line monitoring system have led to a renewed interest in wireless sensor network which is characterized by the real-time and reliability. However, there is increasing concern that the basic ant colony algorithm are being disadvantaged because of the slow convergence and the issue of local optimality, so this paper focused on a new method of adaptive ant colony algorithm to solve the problem of optimal path which was verified by the simulation. In order to seek the optimal path for data transmission in wireless sensor network, considered the network bandwidth, delay, hop count and packet reception rate as link constraints in the abstract model of wireless senor network with long-chain structure. The results show that the optimal QoS path can be quickly found via the adaptive control of the pheromone, at the same time, the quality of service for data transmission in wireless sensor network can be guaranteed.......
