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...

IntroductIon Wireless ad hoc networks have attracted extensive attention among researchers in recent years. As the research activities matured, it has been widely realized that security in such networks is a major issue, and an extremely challenging one. The challenge arises mainly from the inherent AbstrAct Intrusion detection in ad hoc networks is a challenge because of the inherent character...

Much progress has been made toward solving the problem of routing packets inside an ad hoc network, but there are presently no complete proposals for connecting ad hoc networks together to form larger networks, or for integrating them with wired internets. This paper describes a technique that allows a single ad hoc network to span across heterogeneous link layers. Using this technique, we can ...
