Abstract

In this chapter we discuss cooperative source and channel coding strategies and their performance in very dense sensor networks. In particular we investigate how the efficient acquisition of correlated data mandates that the node transmit cooperatively, instead of contending to report their local information. This is important as correlated information it is one of the remaining resource to tap into, to overcome the capacity limitations of large scale wireless networks. We indicate a simple approach to attain this objective by converting the data retrieval process into a querying strategy, where each query is used to convert the correlated data into cooperative codes, which are broadcasted over the wireless channel. We show that over a Markovian field the method would provide a reliable mean to broadcast the correlated information to the whole network with a delay that is on average in the order of the aggregate entropy of the data field.
