We provide a survey on security features and threats to existing Instant Messaging (IM) networks and discuss how currently available systems fail to provide adequate security in l...
Let H = (V, E) be a hypergraph. A conflict-free coloring of H is an assignment of colors to V such that in each hyperedge e E there is at least one uniquely-colored vertex. This ...
In mobile ad hoc network research, simulation plays an important role in determining the network characteristics and measuring performance. On the other hand, unrealistic simulatio...
In this paper we discuss the dynamic network characteristics of mobile ad hoc networks, and explore problems that arise when attempting to provide QoS support in this environment....
Wireless sensor networks are built upon a shared medium that makes it easy for adversaries to conduct radio interference, or jamming, attacks that effectively cause a denial of se...
