Federating disjoint segments may be necessary in some applications of wireless sensor
networks (WSNs). The segments can be simply distinct WSNs that operate autonomously or …

Federating Wireless Sensor Networks (WSNs) in Outdoor Environment Monitoring (OEM)
becomes a necessity as advances in sensing technologies are achieved. Where several …

In some applications of wireless sensor networks (WSNs), it may be necessary to link a
number of disjoint segments in order to form a federated system. The segments can be …

Advances in sensing and wireless communication technologies have enabled a wide
spectrum of Outdoor Environment Monitoring applications. In such applications, several …

Wireless sensor networks (WSNs) often operate in a harsh environment such as battlefield
and may suffer simultaneous failure of multiple sensors that cause the network to become …

We consider in this letter the problem of constrained relay node (RN) placement where
sensor nodes must be connected to base stations by using a minimum number of RNs. The …

Energy consumption is a crucially important issue in battery-driven wireless sensor networks
(WSNs). In most sensor networks, the sensors near the data collector (ie the sink) become …

Wireless sensor networks (WSNs) often operate in severe surroundings and may suffer
simultaneous failure of multiple nodes which gets the network partitioned into distinct …

Wireless sensor networks are formed with very small sensor devices with limited energy and
short transmission range. Sensors are randomly deployed in remote areas with harsh …

In two-tiered wireless sensor networks (WSNs), relay node placement is one of the key
factors impacting the network energy consumption and the system overhead. In this paper, a …
