Wireless Mesh Networks recently attract significant interests due to the minimal infrastructure demands and their potential for supporting mobile and pervasive computing. This work introduces a routing scheme to find best performance routes in WLAN mesh networks. A cross-layer approach is used to overcome self-interference issue of existing load-aware routing metrics. The proposed routing metric was evaluated on a multi-hop wireless emulator which allows us to emulate wireless networks on a wired testbed. Design and implementation of AEROMAN (Architecture to Evaluate Routing Protocols for Multi-hop Ad-hoc Networks) used in the emulator are presented. AEROMAN is the first, to the best of our knowledge, fully distributed approach taking into account properties of contention-based media access for wireless channel, and does not require any special hardware to emulate wireless channel.

The next-generation of wireless communications are envisioned to be supported by heterogeneous networks by using various wireless access technologies. The popular cellular networks and wireless local area networks (WLANs) present perfectly complementary characteristics in terms of service capacity, mobility support, and quality-of-service (QoS) provisioning. The cellular/WLAN interworking is an effective way to promote the evolution of wireless networks. Interworking of Wireless LANs and Cellular Networks focuses on three aspects, namely access selection, call admission control and load sharing to investigate heterogeneous interworking for cellular/WLAN integrated networks. It not only reveals important observations but also offers useful tools for performance evaluation. The unique traffic and network characteristics are exploited to enhance interworking effectiveness. Theoretical analysis and simulation validation demonstrate benefits of cellular/WLAN interworking in real networks. Last but not the least, this brief highlights promising future research directions to guide interested readers.

IEEE 802.11 technologies have penetrated the networking market in the due to their flexibility and easiness of deployment. 802.11 technolgy refers to a wireless local area network that uses radio frequency instead of wires. Different applications place different requirements on server based wireless local area network(SWLAN) in order to achieve better performance and QoS. The study aims to evaluates the performance and QoS of SWLAN on the basis of average throughput, end to end delay and packet loss. WLAN infrastructure architecture model Wlan with AP is selected to implement the proposed design for different number of stations (10,20,40), different type of protocols 802.11 (a,b,g) and different types of applications FTP and DB. All scenarios were applied using OPNET14.5 modeler as a Simulation tool. The effect of varying protocol with different number of stations and applications load were observed on the throughput, delay and packet loss.increase numbers of stations, protocols used may affect the performance and QoS of WLAN. The simulation result shows that after chose best scenario, the network consists of 40 station with medium load application, for 802.11 protocol is the best.

OPNET is a simulation software tool with rich and complex set of libraries to model, configure and simulate the entire heterogeneous network. Computer network of the Campus consists of access points, switches, routers, servers etc. The model on OPNET is configured and simulated to analyze traffic load, delay, data rate, LAN and WLAN characteristics, ping reports and network efficiency. The project results in best settings for our network and can predict the cost, traffic behaviors, throughput and efficiency of the network beforehand. I will be using the OPNET (Optimized Network Engineering Tools) to find a delay, load and throughput of network by applying different network conditions. After analyzing the results through graphs I will choose the best setting for network.

In this book, the performance of voice and video traffic are analysed by investigating the effect of implementing VPN over WLAN on the basis of different quality of service parameters. Initially, quality of service parameters like packet delay variation, mean opinion score (MOS), packet end to end delay are considered. Three scenarios namely 'without firewall', 'with firewall' and 'firewall with VPN' are used. Then, quality of service parameters like throughput, load, delay, data dropped, media access delay, traffic received and traffic sent are focussed.
