This paper deals with the problem of medium access control (MAC)-layer fair power control in a wireless mesh network with an established network topology. The notion of MAC-layer fairness is defined along similar lines as end-to-end fairness for elastic traffic, except that instead of end-to-end flows, MAC-layer flows are considered, being that one hop(More)
In future wireless cellular networks the data-based services are expected to outnumber the traditional voice connections. Such evolution requires the utilization of appropriate transmission policies providing certain goals associated with physical and data link layer, like e.g. total throughput maximization, total delay minimization, fairness in terms of(More)
The philosophy of scheduler design in modern wireless data networks exposes the tendency towards layer-spanning optimization (cross-layer design). An important particular goal of joint design of the physical and (data) link layer appears to be the achievement of the entire stability region of the network. In this work, we provide the optimization-theoretic(More)
Future wireless cellular systems are expected to carry a hybrid traffic including traditional voice transmissions delay-sensitive traffic and high-rate, delay-insensitive data links. In this context there arises the problem of efficient resource allocation, which is optimal with respect to a multiuser QoS (quality of service) functional of interest This(More)
In wireless networks, a widely studied approach is to minimize transmit powers subject to some quality-of-service constraints. Minimizing transmit powers however is not equivalent to minimizing the energy consumption. In wireless sensor networks that operate in a low-rate regime, the discrepancy between power consumption and the overall energy consumption(More)
