Relay Assisted MIMO Transmission System

Abstract
Relay assisted Multiple Input Multiple Output transmission system (MIMO) are expected to be a part of future infrastructure based wireless networks. Besides coverage extensions, such relays can posses high transmission rates, higher speed and larger capacity than its predecessors. MIMO opens a new dimension for wireless broadband communication, mobile wireless access. In this paper we present th ....etc

Abstract

A geometric relationship and mathematical model of pressure angle of elliptical gears are developed based on the theory of gearing, and some constraints of pressure angle are presented in order to prevent gear teeth from coming out of mesh. The results show that the pressure angl ....etc

Network border patrol: preventing congestion collapse and promoting fairness in the Internet

Abstract: The Internet's excellent scalability and robustness result in part from the end-to-end nature of Internet congestion control. End-to-end congestion control algorithms alone, however, are unable to prevent the congestion collapse and unfairness created by applications that are unresponsive to network congestion. To address these maladies, we propose and investigate a novel congestion-avoidance mechanism called network border patrol (NBP). N ....etc

Connectivity Restoration in Wireless Sensor and Actor Networks

Abstract

Recent years have witnessed a growing interest in applications of wireless sensor and actor networks (WSANs). In these applications, a set of mobile actor nodes are deployed in addition to sensors in order to collect sensors data and perform specific tasks in response to detected events/objects. In most scenarios, actors have to respond collectively, which requires interactor coordination. Therefore, maintaining a connected interactor network is critical to ....etc

Abstract We consider the problem of relay-assisted transmission for cellular networks. In the considered system, a source node together with relay nodes are selected in a proportionally fair (PF) manner to transmit to the base station (BS), which uses the maximal ratio combining (MRC) to combine the signals received from the source node in the first half slot and the relay nodes in the second half slot for successful reception. The proposed algorithm incorporates the PF criterion and cooperative diversity, and is called proportionally fair c ....etc

Energy-Efficient Routing in Mobile Ad Hoc Networks: Mobility-Assisted Case (Java)
IEE Transactions on Vehicular Technology, Vol. 55, No. 1, January 2006

Abstract:
Because of node mobility, mobile wireless networks experience rapid variations in the channel strengths, which could potentially be exploited for more cost-effective communications. The pioneering work by Grossglauser and Tse first demonstrated that a network under sufficient amount of random mobility can provide a larger scaling rate of capacity than a static network, at ....etc

Abstract

The emergence of scientific applications that produce huge volume of data files requires special attention, and leads to the problem of how to manage and share such data files in wide area properly. In large-scale Grid, data replication provides a suitable solution for managing data files where data reliability and data availability are enhanced. Replica selection is one of the major functions of data replication that decides which replica location is the best for Grid users. In this paper, we address the replica sele ....etc
