Center node: "on the throughput maximization in dencentralized wireless networks"
  Abstract: A distributed single-hop wireless network with K links is considered, where the links are partitioned into M clusters each operating in an orthogonal subchannel with bandwidth W . We consider a general shadow-fading model, described with parameters (; $), where denotes the probability of shadowing and $ represents the average power of the cross-link channels. The main goal of this paper is to maximize the network throughput. This is achieved by: i) proposing a distributed and non-iterative power allocation strategy, where the objective function for each user is to maximize its best estimate (based on its local information, i.e., direct channel gain) of the average network throughput, and ii) choosing the optimum value for 1 M K. We analyze the throughput of the network in terms of M and (; $) in the asymptotic case of K ! 1. It is proved that when the number of links is large, the optimum power allocation strategy for each user is the threshold-based on-off power scheme (i.e., links with a direct channel gain above certain threshold transmit at full power and the rest remain silent). Under the on-off power scheme, it is demonstrated that the maximum achievable network throughput for every value of 1 M K, 0 < 1 and $ 1 is achieved at M = 1.
