Abstract
In this paper we propose a scheme for rate adaptive lossless distributed source coding scheme for wireless sensor network. We investigate the distributed source-channel coding of correlated sources when correlation parameter is not fixed or may change during sensor network operation. For achieving rate adaptability we propose the puncturing and extension of IRA code depending on the value of correlation between two sources and the quality of channel. In our scheme we need to transmit only incremental redundancy for decreased correlation or fall in channel quality to meet energy constraints and reducing computation cost.
