Abstract [en]

In this letter, we analyze the transmission capacity of selection cooperation (SC) in wireless ad-hoc networks. We first derive the distribution of decoded relay set which follows inhomogeneous Poisson point process (PPP) and then present the closed-form expressions for the outage probability and transmission capacity. Furthermore, we propose an upper bound of source node density given an outage probability constraint and find an optimal transmitter density at which the transmission capacity reaches its maximum. Numerical results show that the performance gain provided by SC can be optimally adjusted by selecting appropriate node density. It is also shown that SC further expands advantage at severer large-scale fading.
