In numerous applications of wireless sensor networks (WSN), the reliability of the data
collected by sensors is cast as specific QoS requirements expressed in terms of the …

Data collection is one of the fundamental functions in wireless sensor networks (WSNs).
Different from a typical WSN with only a single and stationary sink, this paper considers a …

We propose and evaluate a new localization protocol for sensor networks. Contrary to most
current localization schemes, this protocol relies on the existence of only a single beacon …

In a fire rescue operation, a fast, reliable, and robust communication system is needed to
quickly take control of the emergent situation. One of the most important issues in firefighter …

In a typical sensor network environment, sensor energy is considered a precious resource
that must be used wisely and only if necessary. Energy-unaware task assignment protocols …

Wireless sensor networks and personal area networks are two relatively new and emerging
technologies, capable of addressing a large number of applications such as home …

In numerous applications of wireless sensor networks, the reliability of the data collected by
sensors is cast as specific QoS requirements expressed in terms of the minimum number of …

We investigate how to maximize network lifetime by devising a task assignment protocol that
balances task load on sensors based on their remaining energy. First, we show that energy …

Context-awareness is a basic requirement of ubiquitous computing applications. While lots
of good efforts have been made to deliver context-aware tour guide or museum guide, we …

Quickly building a reliable assessment of an incident is very important in the work of
firefighters. Indoor reconnaissance missions are an essential part of this work. In a …
