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 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)

We consider capacity maximization algorithms for wireless networks with changing availabilities of spectrum. There are n senderreceiver pairs (called links) and k channels. We consider an iterative round-based scenario, where in each round the set of channels available to each link changes. Each link independently decides about access to one available… (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)

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)

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. Players… (More)
