Traffic adaptive communication algorithm within clusters for WSN
流量自适应的无线传感器网络簇内通信算法*

This paper proposed a traffic adaptive communication algorithm in wireless sensor network. The slot of varying length would be allocated to each node according to the amount of data to be transmitted. Node could send full data effectively within the assigned time slot, which would reduce its idle time and saved energy that the node switching back and forth from sleep to active state. Different length of frames consists of different lengths of time slots, while the lifetime of the whole cluster consists of the different length of frames. Compared with traditional TDMA algorithm and BMA algorithm, the simulation results shows that the algorithm not only saves energy consumption but also enhances the channel utilization.
