标题： Distributed Time-Frequency Division Multiple Access Protocol For Wireless Sensor Networks

摘要： 众所周知，生物启发的自维护算法在无线传感器节点中以去中心化的方式实现接近最优的时分多址（TDMA）特性，并且具有非常低的复杂度。我们将这种分布式TDMA方法扩展到多信道（频率）。这是通过扩展协作响应监听的概念来实现的，以平衡所有可用信道中的节点数量。我们证明了新协议的稳定性，并估计了达到平衡系统状态的延迟。我们的方法通过使用TinyOS imote2无线传感器与单信道分布式TDMA和信道跳变方法进行了基准比较。 显示英文摘要

摘要： It is well known that biology-inspired self-maintaining algorithms in wireless sensor nodes achieve near optimum time division multiple access (TDMA) characteristics in a decentralized manner and with very low complexity. We extend such distributed TDMA approaches to multiple channels (frequencies). This is achieved by extending the concept of collaborative reactive listening in order to balance the number of nodes in all available channels. We prove the stability of the new protocol and estimate the delay until the balanced system state is reached. Our approach is benchmarked against single-channel distributed TDMA and channel hopping approaches using TinyOS imote2 wireless sensors.
