Distributed Source Coding Algorithm Suitable for Clustering Wireless Sensor Network

Since intensive wireless sensor networks have a lot of redundant information deficiencies, this paper applies clustering wireless sensor networks, distributed source coding algorithm discussed analysis. This algorithm initial reference source as side information source through a correlation between all sources to determine the coding sequence for the reference signal source, and, after the source through the respective reference signal for its corresponding source code, based on the reference signal source and the associated coding sequence of the receiving end decoded. Meanwhile, according to the encoding method modulus value, come up with a less complex decoding algorithm. Simulation and theoretical analysis results confirmed that the algorithm for clustering routing protocol applications, can greatly reduce the number of bits sent by the nodes, so as to realize the reduction of energy consumption, and extend the network lifetime.
