The complex data transfer applications, such as the telephony, video on demand and multimedia conferencing, have become a fundamental requirement. The aim of these applications is to accelerate the information transfer as audio and image packets flows format, comparing to other data formats. The architecture of services' differentiation was suggested as a simple solution to provide different quality...
The measurement and improvement of flow in the WMN wireless mesh networks is still a subject of research, making it an issue of importance for the development of 802.11s standard. The objective is to estimate their capacity to better manage traffic and ensure good quality of service QoS. The capacity of a WMN is one of the most important characteristics; it reflects the load of traffic it can flow...
Blind Flooding is the simplest broadcasting operation used in a wireless mesh network (WMN) based IEEE 802.11s. However such mechanism can significantly degrade the network performance due to the considerable amount of broadcast traffic a WMN may face. Actually, routing relies heavily on layer two broadcasting and WMNs may bridge wired networks which deploy many broadcasting based application. In...
Channel Assignment in Wireless Mesh Networks has to ensure connectivity, and guarantee an acceptable throughput. This problem, being NP-hard, must be solved taking into account all the parameters that influence the output of the proposed algorithm. In this paper, we propose an efficient multi-objective optimization model that, simultaneously, optimizes two conflicting objective functions in order...
Wireless mesh networks have seen a real progress because of their implementation at a low cost. Thus, the planning of such networks presents many challenges for network operators. Our aim in this paper is to provide a new solution for the relays placement problem using a multi-objective optimization approach.
In wireless multi-hop networks, broadcasting by flooding generates frequent retransmissions of unnecessary packets that participate heavily in increasing contention and collision probability. These problems become increasingly likely in a wireless mesh network which can interface to other external networks, thus leading to a significant increase in broadcast traffic. In this paper we have focused...
