Wireless Mesh Network (WMN) is an ad-hoc network with a fixed network infrastructure (see an example in figure 1). The physical structure of a WMN includes base stations, a backbone and mobile stations. The base stations (also known as mesh routers or mesh points) are static wireless nodes, forming the network infrastructure and providing wireless network access to the mobile stations. The back...

in vehicular ad hoc networks there is the ability to communicate between vehicles. this communication which is wireless should be rapid and reliable. these networks have unique characteristic. this communication among vehicles has many advantages in safety and comfort applications. since, the roads are always encountered to accidents and risks, using optimized tools could be useful in these sit...

Adaptive Quality of Service for Wireless Ad hoc Networks Seoung-Bum Lee This thesis contributes toward the design of a new adaptive quality of service (QOS) paradigm for wireless ad hoc networks. We address some of the key performance problems in the broader realm of wireless ad hoc networks, including mobile ad hoc networks and emerging wireless ad hoc sensor networks. Wireless ad hoc networks...

Wireless ad hoc networks are growing important because of their mobility, versatility, and ability to work with fewer infrastructures. The mobile ad hoc network is an autonomous system consisting of mobile nodes connected with wireless links. Establishing a path between two nodes is a complex task in wireless networks. It is still more complex in the wireless mobile ad hoc network because every...

A wireless ad hoc network is a collection of wireless nodes that can dynamically self-organize into an arbitrary and temporary topology to form a network without necessarily using any pre-existing infrastructure. These characteristics make ad hoc networks well suited for military activities, emergency operations, and disaster recoveries. Nevertheless, as electronic devices are getting smaller, ...

Mobile ad hoc networks (MANET) represent complex distributed systems that comprise wireless mobile nodes that can freely and dynamically self organize into arbitrary and temporary ad hoc network topologies. A mobile ad hoc network is a collection of nodes that is connected through a wireless medium forming rapidly changing topologies. The widely accepted existing routing protocols designed to a...

Wireless communication is a technology that simplify the daily life and to narrow the distance between people. Unfortunately throughput limitation of wireless networks is limiting the performance of wireless networks. In order to increase the throughput of the wireless network, network coding has been proposed to increase the throughput of network. Unlike conventional store-and-forward method, ...

MANET stands for Mobile Ad hoc Network. An ad hoc network is often referred to as an “infrastructure less” network, because the network does not need fixed routers [1]. These nodes are mobile communicating through wireless medium. Each ad hoc node may be capable of acting as a router. It’s characterized by multi-hop wireless connection and frequently changing networks. In this paper we evaluate...

In ad hoc wireless networks, wireless terminals can autonomously construct and can maintain the network. They communicate with some neighbor terminals, exchange network information and determine routes for packets on the multi-hop wireless network. Flexible Radio Network (FRN), one of the ad hoc wireless network systems, adopts a proprietary protocol that provides a multiple routes management a...
