We study algorithms for wireless spectrum access of $n$ communication requests when interference conditions are given by the Rayleigh-fading model. This model extends the recently popular deterministic interference model based on the signal-to-interference-plus-noise ratio (SINR) using stochastic propagation to address fading effects observed in reality. We(More)
We study two (classes of) distributed algorithms for power control in a general model of wireless networks. There are n wireless communication requests or links that experience interference and noise. To be successful a link must satisfy an SINR constraint. The goal is to find a set of powers such that all links are successful simultaneously. A classic(More)
We consider capacity maximization in wireless networks under adversarial interference conditions. There are <formula formulatype="inline"><tex Notation="TeX">$n$</tex></formula> links, i.e., sender-receiver pairs, which repeatedly try to perform a successful transmission. In each time step, the success of attempted transmissions depends on interference(More)
Due to limited batteries in mobile communications, network participants are confronted with a trade-off between transmitting more often or with more power. In this paper, we examine the situation arising from selfish utilization of the spectrum game theoretically. We design a game, called Transmission Probability Control Game with Limited Energy.

The defining property of wireless networks is that communications are not done over a wired connection. In contrast, radio spectrum is used which is subject to a variety of influences. Especially, interference from other concurrent transmissions can cause communication attempts to be unsuccessful. Wireless devices have to operate and perform transmissions(More)
