Energy-Efficient SINR-Based Routing for Multi-hop Wireless Networks.

Abstract:

In this paper, we develop an energy-efficient routing scheme that takes into account the interference created by existing flows in the network. The routing scheme chooses a route such that the network expends the minimum energy satisfying with the minimum constraints of flows. Unlike previous works, we explicitly study the impact of routing a new flow on the energy consumption of
the network. Using implementation. We show that the routes chosen by our algorit ....etc

Distributed power control and spreading gain allocation
in CDMA data networks
Abstract
We study the radio resource allocation problem of distributed joint transmission power control
and spreading gain allocation in a DS-CDMA mobile data network. The network consists of
K base stations and M wireless data users. The data streams generated by the users are treated
as best-effort traffic, in the sense that there are no prespecified constraints on the quality of the
radio channels. We are interested in designing a distributed algorit ....etc

Title: cognitive radio systems

Abstract

Efficient use of radio spectrum is a necessity for future wireless systems. While the vast majority of the frequency spectrum is licensed to different organizations, observations provide evidence that usage of the licensed spectrum is by far not complete

neither in the time domain nor the spatial domain. This material discusses basics of Cognitive radio (CR), classifications of

cognitive radio systems, cognitive system architecture, antenna design for cognitive radio system.

Abstract
We investigate the problem of streaming multiplevideos over multi-hop cognitive radio (CR) networks.Fine-Granularity-Scalability (FGS) and Medium-Grain-Scalable(MGS) videos are adopted to accommodate the heterogeneityamong channel availabilities and dynamic network conditions.We obtain a mixed integer nonlinear programming (MINLP)problem formulation, with objectives to maximize the overallreceived video quality and to achieve fairness among the videosessions, while bounding the collision rate with primary usersunder the presen ....etc
