IEEE 802.11 MAC protocol is the standard for wireless LANs, it is widely used in testbeds and simulations in the research for wireless multi-hop ad hoc networks. However, this protocol was not designed for multi-hop networks. Although it can support some ad hoc network architecture, it is not intended to support the wireless mobile ad hoc network, in which multi-hop connectivity is one of the m...

Mobile ad hoc networks are dynamically organized by a collection of wireless mobile nodes. The mobile nodes in ad hoc networks can move arbitrarily thus the topology of network changes dynamically. Due to the properties of communication medium in wireless networks, unidirectional links may exist between mobile nodes thus results in the difficulty of link utilization and routing. In this paper, ...

Future wireless ad hoc networks will use mobile routers to provide Internet connectivity to mobile ad hoc users. A mobile router also allows mobility of an entire ad hoc network, e.g. in plains, trains, cars, and other vehicles, where mobile users may use an Internet access within an ad hoc network domain. Mobile Internet access is also required for various mobile networks such as Personal Area...

Mobile Ad hoc networks (MANETs) are composed of mobile stations communicating through wireless links, without any fixed backbone support. In these networks, limited power energy supply, and frequent topology changes caused by node mobility, makes their routing a challenging problem. TORA is one of the routing protocols that successfully copes with the nodes’ mobility side effects, but it do...

The network structures have changed significantly in the recent years. In spite of the wireless network challenges namely: changes in network topology, high error rates, power restrictions, bandwidth constraints and issues with link capacity, these networks have become popular. Researchers have contributed to a great extent to solve these challenges with innovative solution to support robust an...

Ad hoc wireless networking is currently a hot research area, especially because there is an increasing need for connectivity “anywhere” and, in particular, “anyhow.” While traditional networks have fixed nodes with wired connections (either optical fibers or copper lines), ad hoc wireless networks can be described as multi-hop wireless networks with mobile nodes. However, the mobility condition...

Mobile Ad Hoc Network (MANET) is a collection of wireless mobile nodes dynamically forming a temporary network without the use of any existing network infrastructure or centralized administration. Ad Hoc Networks have the attributes such as wireless connection, continuously changing topology, distributed operation and easy of deployment. Each node operates not only as an end system, but also as...

With the current increase in ad-hoc mobile networks in public domains (e.g. airports, cities, etc.), and the widespread use of the IEEE 802.11 standard in wireless LAN, there is a growing need to handle and manage fast mobility. Optimized Link State Routing protocol (OLSR) is a proactive protocol that enables routing in Mobile Ad-hoc NETworks (MANETs). Fast-OLSR is a new extension of OLSR desig...

Mobile ad hoc networks are wireless multi-hop networks with a completely distributed organization. The dynamic nature of these networks imposes many challenges on mobile ad hoc routing protocols. Current routing protocols do not take into the account the network context and therefore their performance is only optimal under certain network conditions. This paper proposes a novel concept for rout...
