A wireless ad hoc network is a decentralized type of wireless network. The network is ad hoc because it does not rely on a pre-existing infrastructure, such as routers in wired networks or access points in managed (infrastructure) wireless networks. Instead, each node participates in routing by forwarding data for other nodes, so the determination of which nodes forward data is made dynamically...

The present document is essentially a summarized version of the dissertation that will be developed within the scope of an MSc degree in Communication Networks, in the area of security in wireless ad hoc network. Wireless ad hoc networking is a technology that allows fast, easy, and inexpensive network deployment. Unfortunately, these advantages also make the task of an attacker simpler, as it ...

A Wireless ad hoc network is a collection of wireless mobile nodes that dynamically form a network connection temporarily without any support of static infrastructre. The dynamics of an ad hoc network are a challenge to protocol design because mobility of nodes leads to unstable routing, and consequently flows encounter fluctuations in resource availability on various paths during the lifetime ...

A mobile ad hoc network is a collection of autonomous nodes that communicate with each other by forming a multi-top wireless network. Different from conventional wireless networks, the resource of the nodes in ad hoc networks is limited and there may be tens of thousands of low-power energy constrained nodes in ad hoc networks. As such, the costs of the nodes resource and the network size shoul...

An autonomous wireless local area network (AWLAN) is a collection of wireless computers that can be rapidly deployed as an ad hoc network without the aid of any established infrastructure or centralized administration. However, existing routing protocols for such networks neither scale nor function on the Internet. Therefore, a solution is required that provides a gateway between the ad hoc net...

Ad-hoc wireless networks are defined as the category of wireless networks that utilize multi hope radio relaying and are capable of operating without the support of any fixed infrastructure. Wireless mesh networks and wireless sensor networks are specific examples of wireless ad-hoc networks. This paper discusses in detail the functioning of AODV and DSR routing protocol In different propagatio...

The application environments and connection with the Internet require that wireless ad hoc networks should support Quality-of-Service (QoS). In a wireless ad hoc network, supporting quality-of-service is very difficult because of the inherent characteristics of wireless channel and the frequent change of network topology. This paper comprehensively summarizes and deeply analyzes the researches ...

the intelligent transportation system (its) provides wireless and mobile communication between vehicles and infrastructure to improve the safety of transportation and make the journey more enjoyable. this system consists of many fixed and mobile nodes (vehicles, trains, vessels, air planes), wireless and wired telecommunication technologies to exchange information between mobile nodes or betwee...

Routing is a challenging problem for wireless ad hoc networks, especially when the nodes are mobile and spread so widely that in most cases multiple hops are needed to route a message from one node to another. In fact, it is known that any online routing protocol has a poor performance in the worst case, in a sense that there is a distribution of nodes resulting in bad routing paths for that pr...

Abstract: Mobile ad hoc network is a collection of wireless mobile hosts which are interconnected by a communication media like radio. The communication network is formed without the aid of any centralized authority or preexisting infrastructure. By its characteristic this type of network is self-starting and self-organizing. It has been observed that mobile ad hoc networks can be exploited for...
