Özdenizci Köse, Büşra; Ok, Kerem; Coşkun, Vedat (Springer US, 2013-02)Near Field Communication (NFC) as an emerging technology is currently leveraged by large standardization efforts and tries to find a suitable ecosystem. NFC enabled mobile devices with integrated smart cards introduce ... -
Quarantine region scheme to mitigate spam attacks in wireless sensor networks
Coşkun, Vedat; Çayırcı, Erdal; Levi, Albert; Sancak, Serdar (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
Çayırcı, Erdal; Coşkun, Vedat; Çimen, Çağhan (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 ... -
Relocating sensor nodes to maximize cumulative connected coverage in wireless sensor networks
Coşkun, Vedat (Molecular Diversity Preservation Int, 2008-04)In order to extend the availability of the wireless sensor network and to extract maximum possible information from the surveillance area, proper usage of the power capacity of the sensor nodes is important. Our work ... -
