uDisC: An ultra-lightweight and distributed scheme for defending against data loss attack in RFID networks

Abstract

RFID network is applied as a key networking architecture in Internet of Things. It can be largely deployed for object localization and tracing. As the number of RFID tags may be large or the speed of tags may be fast, the reader may misreading some tags. Thus, the data consistence is damaged in central RFID database. Currently, many solutions are proposed for this problem. However, few of them paid much efforts in computation overhead and response delay. Especially, most of them are after-event response, but not in-networking process. In this paper, we make the first attempt to solve the problem on-site. We propose several algorithms for check the missing of tags in real-time. We also propose an adaptive random checking method, called uDisC. Our solution is ultra-lightweight and with the delay bounded by a threshold value that can be manually tuned. © 2012 Springer-Verlag.
