对于无线传感器网络中的数据采集应用，在分布式TDMA调度算法中保证干扰感知的时隙分配是一项艰巨的任务。提出了一种新的基于节点协作的时隙调度算法，解决了节点尝试为其分配时隙时的时隙冲突问题。网络初始化时间按轮次划分。协作由请求、应答和确认三个阶段组成，用于保证每一轮的干扰感知时隙分配。节点在执行协作时交换时隙信息。我们使用NS2对算法的性能进行了评估。实验结果表明，与已有算法相比，该算法具有更好的分组接收率和能量效率。
For data collection application in wireless sensor networks, it is a hard task to guarantee interference-aware slot assignment in distributed TDMA scheduling algorithm. This paper proposed a new scheduling algorithm based on the collaboration of nodes to resolve the slot collision when nodes try to assign slots to them. The time of network initialization is divided into rounds. The collaboration consisted of three phases: REQ, REPLY, and ACK is used to guarantee the interference-aware slot assignment during each round. The slot information is exchanged when node execute collaboration. We evaluate the performance of our algorithm by using NS2. The results indicate that our algorithm has better packet receive ratio and energy efficiency than existing algorithm.
