— In this paper we evaluate outage performance of a cooperative transmission protocol over fading channels that requires a number of relaying nodes to employ a distributed space-...
Abstract-- Secure group key distribution and efficient rekeying is one of the most challenging security issues in sensor networks at present. In this paper, Latin square is firstly...
Sensors’ locations play a critical role in many sensor network applications. A number of techniques have been proposed recently to discover the locations of regular sensors base...
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...
We study a novel "coverage by directional sensors" problem with tunable orientations on a set of discrete targets. We propose a Maximum Coverage with Minimum Sensors (MCM...
