We propose and formally characterize a new problem named the dynamic context coverage problem in capabilityconstrained mobile sensor network environments. The goal is to move and ...
Given a query point p, typically the position of a current client, and two datasets S and R, a transitive nearest neighbor (TNN) search returns a pair of objects (s, r) ∈ S × R...
A wireless sensor network has been designed and deployed to gather data from nodes deployed inside glaciers. This paper describes the solutions to power management, radio communic...

We propose and analyze a scalable and efficient region-based group key management protocol for secure group communications in mobile ad hoc networks. For scalability and dynamic r...
Recent advances in computer power, network bandwidth, information storage, and multimedia/signal processing techniques have led to a proliferation of multimedia data. As a result,...
