: Pervasive wireless systems have significantly improved end-users' quality of life. As manufacturing costs decrease, communications bandwidth increases, and contextual inform...
In wireless ad hoc networks, all its nodes behave as routers and take part in its discovery and maintenance of routes to other nodes. Thus, the presence of selfish or malicious nod...
Many real–world networks show a scale–free degree distribution, a structure that is known to be very stable in case of random failures. Unfortunately, the very same structure ...
This paper describes a prototype system, ZoneIT, for selectively controlling functionality of mobile devices, e.g. ringing of cellular telephones. ZoneIT exploits the fact that ma...
In a practical system, a message is often encrypted more than once by different encryptions, here called multiple encryption, to enhance its security. Additionally, new features ...
