Wireless sensor network(WSN) is made up of a large number which are deployed in the environment to collect observations. Each sensor node preprocesses and extracts information from the raw observations. Each sensor node also has the ability to communicate with other sensor nodes or a fusion center via wireless channels.
Many aspects of WSNs have been investigated recently, such as efficient routing protocols, distributed data compression and transmission, and collaborative signal processing. We investigate the information processing task at the fusion center.
Radio transmission is one of the major power consumer, and the required transmission power not linear in distance between the transmitter and the receiver. Hence in this thesis, we consider a decision made at local sensor may need to go through multi- hop for minimal energy consumption. Sensor and relay employed decode and forward protocol. We investigate how to transmission reliability and how to combine the reliability and we proposed a fusion rule when observations are encoded by Turbo code.
