Abstract

A MISO cooperative transmission algorithm for clustering wireless sensor network is proposed in this paper. In this algorithm, we choose cooperative nodes according to cooperative threshold, and optimize nodes´ transmission power with finite-rate feedback. Then we analyze the implementation process in detail, derive the method of optimizing parameters. In the end verify this algorithm at simulation platform. The result shows that, this MISO cooperative transmission algorithm for clustering wireless sensor network can reduce transmission power of transmitting nodes effectively. So this algorithm can reduce the energy consumption, and also extend the life cycle of the whole wireless sensor network certainly.
