Wireless communication between sensors allows the formation of flexible sensor networks,
which can be deployed rapidly over wide or inaccessible areas. However, the need to …

In wireless sensor networks (WSNs) nodes often operate unattended in a collaborative
manner to perform some tasks. In many applications, the network is deployed in harsh …

The major challenge in designing wireless sensor networks (WSNs) is the support of the
functional, such as data latency, and the non-functional, such as data integrity, requirements …

A wireless sensor network consists of many low-cost, low-power sensor nodes, which can
perform sensing, simple computation, and transmission of sensed information. Long …

Motivated by the needs of precise carbon emission measurement and real-time surveillance
for CO 2 management in cities, we present CitySee, a real-time CO 2-monitoring system …

One approach to prolong the lifetime of a wireless sensor network (WSN) is to deploy some
relay nodes to communicate with the sensor nodes, other relay nodes, and the base …

Wireless sensor network (WSN) applications, especially those serving in inhospitable
environments such as battlefield reconnaissance, are susceptible to large-scale damage …

Two fundamental functions of the sensor nodes in a wireless sensor network are to sense its
environment and to transmit sensed information to a basestation. One approach to prolong …

In this paper we review and analyze redundancy-based fault-tolerant techniques for the IoT
as a paradigm to support two of the main goals of computer security: availability and …

In wireless sensor networks, relay node placement has been proposed to improve energy
efficiency. In this paper, we study two-tiered constrained relay node placement problems …
