Multicast Optimization and Node Fast Location Search Method for Wireless Sensor Networks Based on Ant Colony Algorithm-

 Wireless sensor network is a new information acquisition and processing technology. A large number of sensor nodes form a network through self-organization including each node integrates sensing unit, processing unit, communication unit and energy supply. The protocol multicast technology of wireless sensor network routing is a means of group communication, which requires information from the source node at the same time sent to multiple destination nodes, routing as the core technology of multimedia networks, its scope of study is extensive, including routing protocols, routing strategy and routing algorithms. In this paper, we mainly study the multicast routing algorithm which is based on Quality of Service (QoS), and introduce the search strategy which is based on the shortest path of pheromone in the process of ant colony feeding. MATLAB ant colony algorithm is also used in the WSN routing protocol multicast problem in the application of the problem solving for local optimization. The result of computer simulation shows that the ant colony algorithm has a better effect on solving the multicast protocol of WSN, and the algorithm can realize the fast positioning and query of wireless sensor network routing nodes.
