In many applications, one is interested in optimally deploying a network of nonidentical nodes to a certain area of interest. These networks may include a multitude of connected autonomous nodes in one or more tiers. We formulate these deployment problems as quantizer design problems where different distortion measures should be associated with different quantization indices.
We discuss fundamental design challenges like the best spatial deployment of nodes to minimize the energy consumption or maximize the sensing accuracy while guaranteeing network connectivity. This is done by developing a quantization theory of heterogeneous reproduction points. We will discuss the characteristics of such a heterogeneous quantization theory and show that some of the standard results of the traditional quantization theory, including Gersho’s conjecture, do not hold.rtain area of interest.
