Cooperative communication for wireless networks has been extensively investigated from the perspective of physical layer design. However, the impact of physical-layer cooperation on the network-layer routing design still remains unclear. In this paper, the authors examine the potential benefit of radio coverage extension from cooperation, and present how to incorporate this feature into the routing design. Specifically, with a series of mathematical formulations and derivations, they quantitatively identify direct and cooperative radio cover ages based on the average Symbol Error Rate (SER) performance requirement, elucidating how cooperative diversity gain can be translated into radio coverage extension.
