As the “last mile” access solutions to the Internet, wireless mesh networks (WMNs) can provide a kind of flexible, low-cost and high-speed multihop communication. At present, WMNs has become the main network fusing all kinds of wireless technology, and is widely applied in various kinds of wireless communications. However, WMNs is vulnerable to various kinds

Localization technology is one of the most fundamental requirements and also one of the key supporting technologies in Wireless sensor networks (WSNs). As the WSN is generally deployed in the hostile environment, the localization of nodes can be disrupted easily by the adverse attackers, which determines the significance of security in localization. Secure localization technique

Ad Hoc network consists of a set of mobile wireless nodes that can communicate with each other without fixed networking infrastructure. Because of the dynamic changes of network topology, limited bandwidth and energy, and distributed architecture, Ad Hoc network is more susceptible to various kinds of attacks.Wormhole is a kind of serious attack against Ad

Mobile ad hoc network (MANET) is a self-organizing and multi-hop network. There is no fixed infrastructure and central controlling nodes in the network. Each node in the network is not just a terminal but also functions as a router. So it is widely used in the environment where no pre-deployed infrastructure is available.The inherently vulnerable

Wireless Ad Hoc network is a kind of dynamic, self-organization and multi-hop wireless network which has no basic infrastructure. Because the establishing of the network is flexible and fast, wireless Ad Hoc network has a very broad application prospect. Meanwhile, because of some of Ad Hoc network’s characteristics such as the absence of infrastructure, frequent

The wormhole is a severe attack that targets the operation of routing protocols in Mobile Ad hoc Networks (MANETs). The popular AODV protocol is also vulnerable to this attack. Several routing protocols have been developed to secure AODV and have shown a great impact to the security of AODV offering authenticity, integrity and non repudiation

With the military reconnaissance, environmental monitoring and other areas of the emergence of wireless sensor networks, security has become an important issue. Wireless sensor network can be destroyed or disabled by wormhole attack. In a typical wormhole attack, the attacker in the network receives data packets and forwards them to another node through high-bandwidth and

The application of wireless sensor network in social practice is wider and wider with the deep development of scientific and technological and social needs in the actual developing. Position information of sensor nodes is crucial, so the scientists have been dedicated to sensor network positioning technology research and have achieved great results in terms of

Along with the development and application of wireless networks, more and more concerns are put on security issues. Compared with their wired counterparts, wireless networks risk much more due to their open and instable wireless channels, severe constrains on wireless terminals, and frequently changed topology. In consequence, wireless network is susceptible to many security attacks,

The history of ad hoc networks can be traced back to 1972 and the DARPA-sponsored Packet Radio Network (PRNET) which goal was to provide packet switched networking to mobile battlefield elements in an infrastructureless, hostile environment. The ad hoc networks have been developping dramatically driven by the wireless technology. Recently, ad hoc networks is regarded
