A throughput aware with collision-free MAC for wireless LANs

无线网络中一种吞吐量优先的免碰撞MAC协议

创新点

本文结合CSMA/CA与TDMA思想的方式,通过利用节点在网络中能感知到其他节点成功传输的特点,使节点选取在上一个虚拟TDMA周期中是第i个成功发送数据的顺序作为在当前虚拟TDMA周期中的发送顺序。由于同一时隙有且仅有一个成功传输的节点,那么所有成功传输的节点都有一个独立的时隙来发送数据,未成功的节点则随机选取剩余的时隙中某一个再次发送数据。这样成功节点间的数据发送不会相互干扰,未成功节点也不会影响到成功节点的传输。并且在一个虚拟TDMA周期中,当所有节点都能成功发送一次数据时就能一直延续下去,实现免碰撞从而获得高吞吐量。
