As the complexity of under the condition of large-scaled resource-constrained multi-project duration optimization problems, it is difficult to give its analysis solution. With the network technology in this paper, taking the minimum number of the multi-project weighted duration as the goal, then establish a mathematical model for the optimization problem. In view of the basic cellular automaton topological...
Providing guaranteed quality-of-service (QoS) for resource-hungry multimedia applications over wireless fading channels is challenging. Traditional layered architecture fails miserably in providing the QoS requirement of high throughput, low latency demand of these kinds of applications in wireless mobile networks. Cross-layer design approaches are critical for efficient utilization of the scarce...
Distributed Web crawling (DWC) over DHTs is proposed to solve the bottlenecks in the traditional Web crawling. The core of this kind of system is its fully distributed task scheduling mechanism in which the crawlers are treated as peers and the crawlees are treated as resources maintained by the peers. A system model based on the content addressable network (CAN) can further optimize the scheduling...
We introduce the problem of joint routing, scheduling and power control for multiple information flows in half-duplex, interference limited ad-hoc networks. The joint problem of optimizing for throughput is NP-Hard, and so we present an approximation of the problem and a general framework for solving it in O(N3) time. We attack the problem in two ways, first by presenting a reformulation and decomposition...
In the wireless networks, the power saving is highly important. The way of power saving by resource allocation and scheduling is attached more attention on recently. This paper explores optimal and suboptimal scheduling strategy for a multi- carrier system over fading channels. The scheduling objective is to minimize the average system power under the delay constraint. Specifically, we study the trade-offs...
