Broadband access to the Internet at home was the first step in the emergence of so called Home Networks. In a close future, the number of appliance connected will rise and the network will become the home backbone. This lead us to a mesh architecture, in which routing will be mandatory. This paper introduces a complete system to, first, pilot the forwarding in order to ensure a proper quality of experience;...
Nowadays, Wireless Mesh Networks (WMN) are increasingly supporting jointly non real-time and real time applications that required a guaranteed bandwidth. A new methodology is presented throughout this study to show that an important aspect of dimensioning WMNs, considering mobility of users, fairness and their demand according to two types of running applications. This leads to satisfying voice demand...
IEEE P1900.4 is an emerging standard for optimized radio resource utilization where cognitive radio technologies are used for efficient spectrum utilization. In this paper, we design and implement a cognitive wireless network system based on open documents of IEEE P1900.4, and evaluate its performance using UDP streaming and HTTP download. Our experiments show interesting results that total network...
This paper describes a methodology for building a reliable internet core router that considers the vulnerability of its electronic components to single event upset (SEU). It begins with a set of meaningful system level metrics that can be related to product reliability requirements. A specification is then defined that can be effectively used during the system architecture, silicon and software design...
In this paper, we introduce a pricing model that ensures efficient resource allocation that provides guaranteed quality of service while maximizing profit in multiservice networks. Specifically, a dynamic allocation policy is examined that relies on online measurements while each service class operates under a probabilistic bound delay constraint. We present a rigorous analysis of the properties of...
