In this paper, we obtain the capacity region for the AWGN Multiple Access Channel (MAC) with transmitters equipped with energy harvesters. We then develop low delay, adaptive transmission strategies that surprisingly achieve near optimal performance under finite battery resource constrained settings for the flat fading MAC. We describe the rate-fairness tradeoff inherent to the MAC and adapt th...

In multiuser rate allocation in a wireless network, strategic users can bias the rate allocation by misrepresenting their bandwidth demands to a base station, leading to an unfair allocation. Game-theoretical approaches have been proposed to address the unfair allocation problems caused by the strategic users. However, existing approaches rely on a timeconsuming iterative negotiation process. B...

| We study fairness when receivers in a multi-cast network can not subscribe to fractional layers. This case arises when the source hierarchically encodes its signal and the hierarchical structure is predetermined. Unlike the case of the fractional layer allocation, which has been studied extensively in 14], bandwidth can be allocated in discrete chunks only. Fairness issues become vastly diier...

We study fairness when receivers in a multicast network can not subscribe to fractional layers. This case arises when the source hierarchically encodes its signal and the hierarchical structure is predetermined. Unlike the case of the fractional layer allocation, which has been studied extensively in [29], bandwidth can be allocated in discrete chunks only. Fairness issues become vastly differe...

To mitigate the uplink co-tier interference in heterogeneous networks, advanced receivers are used by Femtocell Base Stations. Orthogonal frequency allocation in interfering cells leads to inefficient spectrum usage. The users can opportunistically access the resources of nearby cells by exploiting the advantage of successive group decoder. Multi cell uplink spectrum allocation with SGD is form...

In this paper, we propose a framework for solving a class of optimization problems encountered in a range of power allocation problems in wireless relay networks. In particular, power allocation for weighted sum-rate and common-rate optimization problems fall in this framework. Subject to some conditions on the region of feasible powers, the optimal solutions are analytically found. The optimiz...

A novel concept in available bit rate (ABR) service model as de ned by the ATM Forum is the minimum cell rate (MCR) support for each ABR virtual connection. In this paper, we present a fundamental study of rate allocation policies with MCR guarantee. In particular, we de ne three network bandwidth allocation policies that guarantee MCR requirements. For each policy, we present a centralized alg...
