The development of dependable mobile P2P systems is an inherently challenging task since such systems may operate in largely uncontrolled environments and may engage new peers or lose existing ones without any form of centralised control. In these circumstances, dependability and security can be enhanced through the runtime monitoring (a.k.a. dynamic verification) of the compliance of the system behaviour...
The security of wireless sensor networks is ever more important nowadays. Most of the proposed security protocols in wireless sensor networks are based on authentication and encryption. But all of them only address part of the problem of security in wireless sensor networks. Recently, the use of reputation and trust systems has become an important secure mechanism in wireless sensor networks. In this...
Mobile computing environments may be very critical for traditional QoS management techniques often relying on centralized resource coordinating services, due to the unavoidable high unstability of network and service layers. On the other hand, a peer-to-peer approach for continuous service provisioning to mobile users may maintain locally an updated list of service providers, and allow clients to...
Traffic congestion on major roadways costs our nation billions of dollars in lost earnings, wasted fuel consumption, injury and loss of human life. Providing motorists with real time roadway conditions is essential to mitigating traffic congestion. We propose a novel real-time messaging system that can be used to communicate imminent traffic conditions to motorists. Having such information can allow...
