In wireless sensor networks (WSN), individual sensor nodes are inherently unreliable and
have very limited capabilities to ensure real-time guarantees. In fact, one of the most …

Directional antennas have been extensively used in designing MAC protocols for wireless
ad hoc networks in recent years. Directional antennas provide many advantages over the …

Wireless LANs not only provide an affective means of communication, but also allow to
extract information about the location of mobile stations. Numerous wireless LAN location …

We introduce a new modelling assumption in wireless sensor networks, that of node
redeployment (addition of sensor devices during the protocol evolution) and we extend the …

Wireless Sensor Networks (WSNs) have been attracting increasing interests in the
development of a new generation of embedded systems with great potential for many …

Numerous MAC protocols have been proposed for stationary wireless sensor networks
(WSNs). However, there have been very few approaches proposed to make the MAC layer …
