The 4th Generation wireless networks are expected to become the access network technology of preference and be fully connected to the Global IP core network. Meanwhile, Mobile Ad hoc Networks (MANET) are typically formed on a temporary basis, to serve some urgent communication needs or extend communications in hot spots that are beyond the transmission range of cellular infrastructures. MANETs ...

Denial of service (DoS) attack is a major class of security threats today. They consume resources of remote hosts or network and make them deny or degrade services for legitimate users. Compared with traditional Internet, the resources, such as bandwidth, memory, and battery power, of each node are more limited in mobile ad hoc networks (MANETs). Therefore, nodes in MANETs are more vulnerable t...

Mobile ad hoc networks (MANETs) are infrastructureless networks formed by wireless mobile devices with limited battery life. In MANETs for civilian applications, the network nodes may not belong to a single authority and they may not have a common goal. These MANETs are particularly vulnerable to selfish behavior, as some nodes may prefer saving resources to forward data. There are a few generi...

Mobile ad hoc networks (MANETs) present similarities with Peer to Peer (P2P) systems in terms of decentralization, equality and autonomy. This results in the rise of new collaborative and spontaneous P2P applications over MANETs such as P2P auctions. The deployment of auctions over MANETS should provide new opportunities to the important marketplace created by mobile communities and may be a ga...

In Mobile Ad hoc Networks (MANETs), certification systems play an important role to achieve network security. Handling the issue of certificate revocation in wired network is somewhat easy compared to the MANETs. In wired network when the certificate of a malicious node get revoked then the certificate authorities add the information about the revoked node in to certificate revocation lists (CR...

Mobile ad hoc networks (MANETs) are a collection of mobile nodes that communicates over wireless media. Performance of MANET depends on the cooperative participation of nodes in packet forwarding. During packet forwarding from source to destination, it takes help of middle hop depending on the distance. Middle hops play different role in different times. Nodes in MANETs suffer from limited reso...

Mobile Ad hoc Networks (MANETs) are considered as a new paradigm of infrastructure-less mobile wireless communication systems. MANETs are being widely studied and it is the technology that is attracting a large variety of applications. Routing in MANETs is considered a challenging task due to the unpredictable changes in the network topology, resulting from the random and frequent movement of t...
