Transmission Channels and Noise Models for Wireless Sensor Networks and Blind Equalization

Abstract

Tetsuya Shimamura

Wireless Sensor Network (WSN) is a self-organized distributed communication network, composed by a number of geographically separated, autonomous and low-cost sensor nodes with limited power and processing capability, which are cooperating with each other to connect and process data from the surrounding through wireless communication. To fulfill a common task, WSN cooperates through the wireless transmission medium. In recent years, WSN has attracted research interest because of its employment on land, underground, underwater and top of mountain, which is very wide. However, there are still obstacles to be more extensively employed. In this work, it is emphasized that blind equalization should be proactively utilized to develop WSNs furthermore. A method based on finding the easiest sensor location is derived and its performance is demonstrated in a comparative fashion.
