— In Wireless Sensor Networks (WSNs), symmetric key schemes may be used to provide security. Recently, a class of random key pre-distribution techniques have been proposed and in...
Group management service plays a key role in wireless sensor networks (WSNs) as it provides support to high level middleware services such as object tracking, security, fault-tole...
—Over the last few years, many researchers have paid a lot of attention to the user authentication problem. However, to date, there has been relatively little research suited for...
Multipath fading heavily contributes to the unreliability of wireless links, causing fairly large deviations from link quality predictions based on path loss models; its impact on...
Wireless sensor networks are typically deployed to measure the information field, rather than create an information field. However, by utilizing the radio on sensor nodes, it is...
