This paper gives an improved alamouti 2*2 strategy in dense wireless sensor networks after analyse the model of communication between the transmitting cluster and receiving cluster. Simulation show the results of energy consumption among worst-channel, random-channel and optimal-channel. Some rules are given in the process of the simulation analyse.
Wireless sensor networks are envisioned by linking existing and emerging technologies of computers, wireless radio communications systems and sophisticated sensors to be used in application. Simulation is an important way to validate algorithm or protocol in wireless sensor networks. First we describe some typical simulation methods in WSN. Then we present a new simulation tool named Truetime and...
