—Wireless networks in combination with image sensors open up a multitude of previously unthinkable sensing applications. Capable tools and testbeds for these wireless image senso...
In this work we define and study a new model for the caching problem in a heterogeneous wireless network under a flash-crowd scenario. Using non-cooperative game theory, we cast t...

Abstract. Electronic payment systems for wireless devices need to take into account the limited computational and storage ability of such devices. Micropayment schemes seem well su...
Bluetooth is a promising new technology that enables portable devices to form short-range wireless ad hoc networks and relies on spread spectrum frequency hopping (FH) techniques f...
We propose a distributed on-demand power-management protocol for collecting data in sensor networks. The protocol aims to reduce power consumption while supporting fluctuating dem...
