We consider the design of optimal strategies for joint power adaptation, rate adaptation and scheduling in a multi-hop wireless network. Most existing strategies for ad-hoc networks control either power and scheduling, or rates and scheduling, but not the three together as we do. We assume the underlying physical layer allows finegrained rate adaptation (like in 802.11a/g, HDR/CDMA, UWB). Our g...

The presence of multiple users in a network provides us with a valuable resource known as multiuser diversity. With information on the instantaneous states of the channels, multiuser diversity can be tapped by opportunistic multiuser scheduling. It is important that the channel state information is acquired in a cost-effective way so that the losses involved in this operation does not offset th...

This paper jointly addresses the problem of power control and scheduling in ad hoc networks supporting multicast traffic. First, we present a distributed algorithm which, given the set of multicast transmitters and their corresponding receivers, provides an optimal solution to the power control problem, if there is any. The transmit power levels obtained by solving the optimization problem mini...

In this thesis, we study the downlink multiuser scheduling and power allocation problem for systems with simultaneous wireless information and power transfer (SWIPT). In the first part of the thesis, we focus on multiuser scheduling. We design optimal scheduling algorithms that maximize the long-term average system throughput under different fairness requirements, such as proportional fairness ...

This paper presents a simplifiedlagrangian multiplier based algorithm to solve the fixed head hydrothermalscheduling problem. In fixed head hydrothermal scheduling problem, waterdischarge rate is modeled as quadratic function of hydropower generation andfuel cost is modeled as quadratic function of thermal power generation. Thepower output of each hydro unit varies with the rate of water discha...

As an important part of energy Internet carrier, demand side resources can participate in many interactions with power grid. In order to reduce the peak valley load difference grid, from perspective tapping combined shaving potential air conditioning and electric vehicles, guided by TOU price direct control, this paper proposes optimal scheduling model minimum maximum total revenue users as obj...

appropriate scheduling and sequencing of tasks on machines is one of the basic and significant problems that a shop or a factory manager encounters; this is why in recent decades extensive studies have been done on scheduling issues. one type of scheduling problems is just-in-time (jit) scheduling and in this area, motivated by jit manufacturing, this study investigates a mathematical model for...
