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 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.
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 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 M ulti-Radio M ulti-Channel Wireless M esh… (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.

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)
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… (More)
Unlike most of proposed solutions that usually consider the overall throughput as the main optimization, Channel Assignment in Wireless Mesh Networks has to ensure connectivity, minimize interference level and guarantee an acceptable throughput. This problem must be solved taking into account all the parameters that influence the output of the proposed… (More)
