Correlated Data Routing in Sensor Networks

We study the correlated information routing with source coding using explicit side information in wireless sensor networks. This problem belongs to the difficult joint compression/routing optimization, and has its connections to the network information theory. We present our network and rate models based on explicit side information available at both the encoder and decoder, then introduce the integer programming formulation with a few simplifying assumptions. A two-stage DPCM coding scheme that can take advantage of the explicit side information and report the additional spatial is also included.
