An Efficient Security Framework for Detection and Isolation of Attackers in Low Rate Wireless Personal Area Networks

Abstract

LR-WPANs mainly target low data rate and short range applications Packet delivery in such networks is achieved through routing and packet forwarding. So we should provide security for both operations. In this paper, these two types of threats within the current LR-WPAN security architecture are identified and an efficient security framework (ESF) is presented. It protects both routing and data forwarding attacks. The framework involves Detection of malicious nodes by the modified AODV routing and isolation of malicious nodes by using multi-signature based tickets. Through both analysis and simulation results, we demonstrate the effectiveness of our framework in detecting and isolating the misbehaving nodes.

Optimised watchdog system for detection of DDOS and wormhole attacks in IEEE802.15.4-based wireless sensor networks

“…This is the most likely mechanism of channel access for the majority of devices in a large network. The low rate and low power wireless personal area networks (LR-WPAN) and sensor networks are the main target of the IEEE 802.15.4 which is basically an extension of the wireless radio and protocol (Jung et al, 2010;Sokullu et al, 2007;Priya and Pradhan, 2008).…”
