The joint power control and base station assignment for downlink is considered in this paper. We present an algorithm that finds a feasible joint base assignment and power control in the downlink which uses the base assignment that is computed by the joint algorithm in the uplink. We show that under some conditions the algorithm. also minimizes the sum of downlink powers. Interestingly, there i...

For a system of nite queues, we study how servers should be assigned dynamically to stations in order to obtain optimal (or near-optimal) long-run average throughput. We assume that travel times between di erent service facilities are negligible, that each server can only work on one job at a time, and that several servers can work together on one job. We show that when the service rates depend...

Abstract: A control architecture for resource allocation in satellite networks is proposed, along with the specification of performance indexes and control strategies. The latter, besides being based on information on traffic statistics and network status, rely upon some knowledge of the fading conditions over the satellite network channels. The resource allocation problem consists of the assig...

In this paper, we present the power control problem in CDMA wireless data networks in the analytical setting of non-cooperative game theory. User satisfaction is represented as a net utility function, which is the difference of a strictly concave function, based on signal to interference ratio, and a cost term on user’s power. A detailed analysis for the existence and uniqueness of Nash equilib...

The limited availability of radio frequency spectrum will require the future wireless systems to use more eecient and sophisticated resource allocation methods to increase network capacity. In this work we propose a Joint Resource Allocation Algorithm (JRAA) that makes the channel base station and power assignment in a wireless network with arbitrary number of base stations and mobiles attempti...

The cable TV (CATV) network is an ideal backbone for PCS due to its prevalent and broadcast nature. This significantly reduces the implementation costs and the handoff overheads. This paper proposes two architectures for the CATVbased PCS system. In the first architecture, each base station is equipped with multiple fixed receivers to provide fast and seamless handoffs for mobile users. Neverth...

Plug-in electric vehicles (PEVs) are a rapidly evolving technology representing a potentially sustainable alternative to traditional internal combustion engine vehicles (ICEVs). By relying on electric power rather than petrol, these new vehicles will require a new infrastructure system for en-route charging options, be that fast charging stations or battery swap stations. PEVs will therefore ge...

Consider a tandem queueing network with an infinite supply of jobs in front of the first station, infinite room for completed jobs after the last station, finite buffers between stations, and a number of flexible servers who are subject to failures. We study the dynamic assignment of servers to stations with the goal of maximizing the long-run average throughput. Our main conclusion is that the...

The airline fleet assignment problem involves assigning aircrafts to flights to maximize profit. Different fleet assignment solutions cause dramatically different performance in subsequent crew planning and operational processes. We have developed an integrated fleet and crew robust planning method to provide fleet assignment solutions that are both friendly to crew planning and robust to real ...
