A Mobile Ad-hoc Network (MANET) is a self-configuring infrastructure less network of mobile devices connected by wireless links. In this network technology, simulative analysis is a significant method to understand the performance of routing protocols. In this paper three protocols AODV, DSDV and DSR were simulated using Manhattan Grid Mobility Model. The… (More)
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… (More)
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… (More)
Wireless mesh networks have seen a real progress due of their implementation at a low cost. They present one of Next Generation Networks technologies and can serve as home, companies and universities networks. In this paper, we propose and discuss a new multi-objective model for nodes deployment optimization in Multi-Radio Multi-Channel Wireless Mesh… (More)
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… (More)
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 to the planning problem using a multi-objective optimization approach. Refer ences I. F. Akyildiz, X. Wang, and W. Wang,… (More)
In this paper, we propose and discuss two new multi-objective models for nodes deployment optimization in Multi-Radio Multi-Channel Wireless Mesh Networks. These optimization problems are solved simultaneously by using meta-heuristic method that returns non-dominated set of near optimal solutions.
Wireless mesh network has recently received a great deal of attention as a promising technology to provide ubiquitous high bandwidth access for a large number of users. Such network may face a significant broadcast traffic that may consequently degrade the network reliability. In this paper, we have focused interest to wireless mesh network based IEEE… (More)

Mobile ad hoc network (MANET) is a collection of several wireless devices or mobile users that can communicate among themselves over wireless links in a peer to peer basis and thereby creating a dynamic, arbitrary graph. But some adverse characteristics of MANET like dynamic topology, limited bandwidth, link failure and energy constraints, imposes new… (More)
