Research on Optimization Selection Algorithm of Track and Field based on Adaptive Wireless Sensor Network Node Speed

By using the adaptive search algorithm of particle swarm layout, we optimize 3D space nodes of wireless network, and obtain the optimum mathematical model of particle swarm optimization distribution of nodes in wireless network. Using the tree structure and the wireless network hardware equipment we design algorithm the optimization platform of track and field technique. In order to verify the stability and reliability of platform running, we use the wireless network node division method and transmission time groups of control network to control athlete's technical movement. And we use Java technology to calculate the athlete's action to verify the stability. Through calculation, for the same optimization task, the time of adaptive search algorithm is short, and the search is less, which is a rapid and effective optimization algorithm.
