Abstract
Concerning the high packet delay and frequent transmission bottleneck in Wireless Sensor Network(WSN) with one-sink node,a multi-sink wireless sensor network model and its Time Division Multiple Access(TDMA) scheduling algorithm based on Genetic Algorithm(GA) were proposed.The algorithm divided the whole sensor network into some small sensor networks according to the number and position of the sink nodes,and adopted GA to optimize the slot allocation result.The simulation results show that,the TDMA time slot allocation method based on genetic algorithm is better in the length of time slot allocation frame,the average of packet delay and the average energy consumption than that of graph coloring algorithm.
