The sectoral sweeper scheme for wireless sensor networks: Adaptive antenna array based sensor node management and location estimation
(Kluwer Academic Publishers-Plenum Publishers, 2006-12)
We introduce a novel sensor node management and location estimation method referred as sectoral sweeper (SS) scheme that uses an adaptive antenna array (AAA) at a central node in wireless sensor networks (WSNs). With the ...
Quarantine region scheme to mitigate spam attacks in wireless sensor networks
(IEEE, 2006-08)
The Quarantine Region Scheme (QRS) is introduced to defend against spam attacks in wireless sensor networks where malicious antinodes frequently generate dummy spam messages to be relayed toward the sink. The aim of the ...
Querying sensor networks by using dynamic task sets
(Elsevier B.V., 2006-05-15)
A data querying scheme is introduced for sensor networks where queries formed for each sensing task are sent to task sets. The sensor field is partitioned into subregions by using quadtree based addressing, and then a given ...
