Ad Hoc wireless networks have their own unique nature of distributed resources and dynamic topology. This nature introduces very special requirements that should be met by the proposed routing protocols for the Ad Hoc networks. This paper reviews the classification of the Ad Hoc networks routing protocols along with emphasizing on the table-driven class of protocols.
The growing success of wireless ad hoc networks and portable hardware devices presents many interesting problems to system engineers. Particular, coordination is a challenging task, since ad hoc networks are characterized by very opportunistic connections and rapidly changing topologies. This paper presents a coordination model, called PeerSpaces, designed to overcome the shortcomings of tradit...
Security is one of the main concerns in modern networks. Given the recent success of wireless networks, there are plenty of possibilities to attack the networks themselves [14][24] or services [28] running on these networks. Current progress in research and growing interest from the industry let also expect more and more sophisticated Ad-hoc networking solutions. Compared with security problems...
Mobile multi-hop ad-hoc networks promise an efficient and very flexible way of establishing a communication connection. One aspect of these kind of networks is their convenience, which is sometimes neglected in research. Especially for civil applications, this aspect of ad-hoc networks need more attention. It is expected that users neither need to know much of networks nor perform complex confi...
Deployed in 1990’s, Mobile Ad-hoc networks have been widely researched for many years. Mobile Ad-hoc Networks are a collection of two or more devices equipped with wireless communications and networking capability. These devices can communication with other nodes that immediately within their radio range or one that is outside their radio range. For the later, the nodes should deploy an interme...
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...
Mobile ad hoc networking is a challenging task due to the lack of resources reside in the network as well as the frequent changes in network topology. Although lots of research have been done on supporting QoS in the Internet and other networks, they are not suitable for mobile ad hoc networks and still QoS support for such networks remains an open problem. In this paper, we provide a brief ove...
Technological advances are leveraging the widespread deployment of mobile ad hoc networks. An interesting characteristic of ad hoc networks is their self-organization and their dependence of the behavior of individual nodes. Until recently, most research on ad hoc networks has assumed that all nodes were cooperative. This assumption is no longer valid in spontaneous networks formed by individua...
Mobile ad hoc networks (MANET) are pervasive, self-configuring, infrastructure-free, and ubiquitous devoid of any centralized authority. Mobile ad hoc networks have proved their efficiency in the deployment for different fields, but they are highly vulnerable to security attacks which is particularly challenging in wireless networks. The existing research that has been carried out provides auth...
