Mobile ad hoc networks are growing in popularity due to the explosive growth of modern devices with wireless capability such as laptop, mobile phones, PDA, etc., makes the application more challenging. The mobile nodes are vulnerable to security attacks. Providing security and anonymity to users are critical in wireless ad hoc networks. Ad hoc networks have lots of applications; however, a vita...

Ad-hoc networks that are connected with the infrastructure Internet are named hybrid ad-hoc networks. In 4G communications scenarios, hybrid ad-hoc networks seem to be valuable since they may increase the coverage of wireless networks with minor costs. Using them, terminals out of range of an access point or a base station, or not having adequate network interfaces, may reach the operator’s inf...

Ad hoc networks have vital problem concerning their security aspects. These must be solved in order to realize complete Ad hoc applications. The dynamic and cooperative nature of ad hoc networks present challenges in securing these networks. There are recent research efforts in securing ad hoc networks. Amongst security approaches, there are threshold cryptography, certification authority, repu...

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...

The exchange of information between vehicles is a challenging issue for future Transportation applications. In vehicular Ad-Hoc network, the vehicles are interconnected with each other and they have not any additional infrastructure along the roadside. Vehicular Ad-hoc networks are eminent from other types of Ad-hoc networks. The Ad-hoc network attributed to their features such as infrastructur...

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...
