Improving data quality using a cross layer protocol in wireless sensor networks

Wireless sensor networks (WSNs) in which the location of sensors is a key information are becoming more and more important. Moreover, in many cases privacy is a key issues for such network which can be the target of different kind of security attacks. In this paper we present an approach, named Cross Layer Protocol (CLP), for improving data quality based on an integrated solution that considers a sound privacy management policy coupled with a secure localization protocol. More specifically, CLP exploits consistency between the information on nodes behavior gathered during localization phase and privacy compliance verification to evaluate nodes reputation. Finally CLP effectiveness is evaluated by means of a set of simulations. (C) 2012 Elsevier B.V. All rights reserved.
