Key set up and distribution in sensor network is a complex task due to inherent limitations in sensor networks. For reducing the “communication and computation overhead” we proposed that the sensor network is partitioned into different zones. Each zone has a separate intrusion detection system (IDS) and key distribution center (KDC).IDS can detect...

A limited and precious resource like the available spectrum has been put to a lot of limitations by the exceeding demand of wireless applications. Recent study has shown that some frequency bands in the spectrum are mainly unoccupied most of the time, while some are less occupied, whereas few bands are over utilized. This leads to spectrum underuti...
