多模无线传感器网络的容量

Capacity of Multi-Modal Wireless Sensor Networks

密集无线传感网络中,可通过配置多个Sink收集节点来观察所监测区域内的多个随机过程,并在相应的Sink节点处重建所观察到的过程。当网络中传感器节点的功率固定时,分析了采用基于波束成形的通信方式时网络的可达容量域,推导出每个过程可获得的传输容量为专(log(N)),并进一步分析了该网络可以同时观察到的随机过程的数目为O(N茁)。

In dense wireless sensor network,several Sink nodes can be deployed to monitor and reconstruct more than one random process in the environment.When the per sensor power is fixed,analyze the network achievable capacity region based on the beamforming communication method ,and deduce thai the transport capacity of each process is θ（log（N））,and the number of process that can be simultaneously monitored is O（N^β）.
