As many radio chips used in today's sensor mote hardware can work at different frequencies, several multi-channel communication protocols have recently been proposed to improv...
Typical packet traffic in a sensor network reveals pronouncedpatterns that allow an adversary analyzing packet traffic to deduce the location of a base station. Once discovered, t...
In this paper we present Beacon Location Service (BLS): a location service for beacon-based routing algorithms like Beacon Vector Routing (BVR) [8] and S4 [19] . The role of a loc...

In this paper we address three challenges that are present when building and analyzing wireless sensor networks (WSN) as part of ubiquitous computing environment: the need for an ...
Abstract— This paper focuses on the Delay/Fault-Tolerant Mobile Sensor Network (DFT-MSN) for pervasive information gathering. We develop simple and efficient data delivery schem...
