An important challenge in mobile sensor networks is to enable energy-efficient communication over a diversity of distances while being robust to wireless effects caused by node mobility. In this thesi...
RWS focuses on the intersection between radio systems and wireless technology, which creates a unique forum for engineers to discuss hardware design and system performance of the state -of-the-art wir...
基于传感器网络中正交信道较少的特点，提出一种Dual-Radio传感器网络中分布式信道分配算法(DCA)，并在此基础上提出一种路由转发策略(RFS)。DCA能够利用较少的信道消除网络路径内冲突、减少路径间冲突。在理论上证明当网络中正交信道个数K≥Δ+1时，网络吞吐量上界为|M|+1，其中Δ为网络拓扑图的最大度，|M|为网络路由树中非叶子节点数。在RFS中，节点通过适时切换发送信道，进一步减少路径间...
