Eliminating False Data and Improving Network Lifetime Using Mobile Data Collector in Wireless Sensor Networks

Abstract

False data elimination during data aggregation and transmission is important in ensuring data integrity in wireless sensor networks. The existing security mechanisms do not address the uneven battery drain due to funneling effect. In this paper, False Data Elimination - Mobile Data Collector scheme is proposed to eliminate the injected false data by multiple compromised nodes during data aggregation and transmission and to resolve the uneven battery drain due to funneling effect by using a mobile data collector.  It ensures confidential data transmission and provides immunity against many attacks. Simulations indicate that it has a higher false data filtering capacity, lesser energy consumption and improved network lifetime
