An ad hoc network is a temporary that consists of wireless mobile hosts. Due to the absence centralized or structured infrastructure, host may need assistance in forwarding packet desired location. This applicable cases whereby limited range transmissions visible Dynamic Source Routing (DSR) simple but effective protocol intended specifically for those networks lack predetermined infrastructure...

In the ad-hoc radio network model, nodes communicate with their neighbors via signals, without knowing topology of underlying digraph. We study information gathering problem, where each node has a piece called rumor , and objective is to transmit all rumors designated target node. For model any collision detection we provide an O ˜ ( n 1.5 ) deterministic protocol, significantly improving trivi...

Ad hoc networks are becoming more and more popular as the use of mobile computing devices increases. While ad hoc networks have many advantageous properties, they also pose several security challenges which are unique to networks of this kind. One of the main challenges that ad hoc networks have to face is authentication. Authentication is difficult to achieve in ad hoc networks because some ty...

Wireless ad-hoc networks have gained a lot of importance in wireless communications. Wireless communication is established by nodes acting as routers and transferring packets from one to another in ad-hoc networks. Routing in these networks is highly complex due to moving nodes and hence many protocols have been developed. Mobile ad hoc networks are networks without fixed infrastructure. The mo...

security term in mobile ad hoc networks has several aspects because of the special specification of these networks. in this paper a distributed architecture was proposed in which each node performed intrusion detection based on its own and its neighbors’ data. fuzzy-neural interface was used that is the composition of learning ability of neural network and fuzzy ratiocination of fuzzy system as...

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...

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...

Wireless ad-hoc networks are infrastructureless and they consist of nodes that come together and start communicating dynamically without requiring any backbone support. The nodes can enter and leave the network at will and can move about in the network at will. Ad-hoc networks present the perfect test-beds for bio-inspired computing algorithms. Both ad-hoc networks and bio-inspired computing ap...

An Ad hoc network is a short-live network in which two or more mobile devices connected to each other without the help of intervening infrastructure. The routing protocols designed for wired networks are different from Ad hoc networks protocols because wired network can't work efficiently in Ad hoc networks. This imposes different design constraints and requirement on routing protocols for...
