– Key management is critical to meet the security goals [1] to prevent the Sensor Networks being compromised by an adversary. Due to ad-hoc nature and resource limitations of sen...
Hop-by-hop data aggregation is a very important technique for reducing the communication overhead and energy expenditure of sensor nodes during the process of data collection in a...
The development of lightweight sensing and communication protocols is a key requirement for designing resource constrained sensor networks. This paper introduces a set of efficien...
Abstract. To process aggregation queries issued through different sensors as access points in sensor networks, existing algorithms handle queries independently and perform in-netw...
