In this paper, the authors propose a cross-layer security scheme for virtual MIMO networks. The scheme combines cryptographic technique implemented in higher layers with data assurance analysis at the physical layer to provide better security. The scheme can, of course, be used for a traditional non-cooperative MIMO network. First, the authors show an efficient key management system that can provide...
The wireless local area network (WLAN) technology has a rapid development because its advantages of fast and high-efficient, flexible and easy in net building. Wireless network brings users convenient network service, but it also hides many security problems that hinder WLAN's development. This paper combines the accountability of IP address with trust routing to a second mechanism applied in WLAN...
Unlike traditional wireless routing protocols which use a single fixed path, opportunistic routing explicitly takes advantage of the broadcast nature of wireless communications by using a set of forwarders to opportunistically perform packet forwarding. A key issue in the design of opportunistic routing protocols is the forwarder list selection problem. In this paper we establish a general theory...
Nowadays most ad hoc mobile devices heavily depend on the performance of batteries. Optimizing the power consumption is a very crucial issue. To maximize the lifetime of mobile ad hoc network, the power consumption rate of each node must be evenly distributed. In this paper we present a novel power-aware routing algorithm based on mobile agents to deal with the routing mechanism in the energy-critical...
