Urbino Wireless Campus (UWiC) is an open wireless access network promoted and implemented by the University of Urbino, in Italy, to virtually extend the University campus over the Montefeltro region, while providing also a significant contribution to bridge the digital divide and promote the widespread diffusion of online services and applications. UWiC has ranked first among the 82 wireless-campus...
As wireless data networks is becoming an essential element in our daily life, service providers are struggling to fulfill the high data rate requirements to support wireless data applications. cdma2000 1xEV-DV, developed by the Third Generation Partnership Project 2 (3GPP2), is one of the latest standards promising to fulfill the high data rate requirements of the third generation wireless technologies...
The goal of this contribution is to show which practical routing approach, for wireless mesh network (WMN) backhaul, is the best for systems presenting a constraint on the total power to be emitted be network nodes by modeling rounting as a power allocation problem. We consider at first multiple-input multiple-output (MIMO) point-to-point capacity-achieving codes, and nodes cooperation. Furthermore...
This paper focuses on the competitively optimal power-control, signal-shaping and interference mitigation for wireless mesh networks composed by multiple-antenna noncooperative transmit terminals and a base station affected by spatially colored multi-access interference (MAI). The target is the competitive maximization of the information throughput of the uplink of each link active over the network...
An algorithm for self-organization that assigns the channels intelligently in multi-radio wireless mesh networks (MR-WMN) is important for the proper operation of MR-WMN. The aim of the self-organization algorithm is to reduce the overall interference and increase the aggregate capacity of the network. This can be possible by addressing the two major challenges that are associated with the self-organization...
this paper we study the performance of TCP with a vertical handoff between access networks with widely varying link characteristics. TCP being an end-to-end protocol has performance problems as its behaviour depends on the end-to-end path characteristics which are likely to be affected by a vertical handoff. We propose a set of enhancements to the TCP sender algorithm that leverage on explicit cross-layer...
In this paper, we give a quantitative evaluation on the effect of integrating WiMAX and Wi-Fi, as compared to the case of separate WiMAX and Wi-Fi systems, on the system capacity with QoS being considered. We focus particularly on the VoIP traffic aspects of the system. Based on this capacity evaluation, a cost analysis is further presented. We also propose and analyze a resource management scheme...
