Attacking and securing beacon-enabled 802.15.4 networks

چکیده
The IEEE 802.15.4 has attracted time-critical applications in wireless sensor networks (WSNs) because of its beacon-enabled mode and guaranteed timeslots (GTSs). However, the GTS scheme's security still leave the 802.15.4 MAC vulnerable to attacks. Further, the existing techniques in the literature for securing 802.15.4 either focus on non beacon-enabled 802.15.4 or cannot defend against insider attacks for beacon-enabled 802.15.4. In this thesis, we illustrate this by demonstrating attacks on the availability and integrity of the beacon-enabled 802.15.4. To proof the attacks, we implement the attacks using Tmote Sky motes for a malicious node along with regular nodes. We show that the malicious node can freely exploit the beacon frames to compromise the integrity and availability of the network. For the defense, we present beacon-enabled MiniSec (BCN-MiniSec) and analyze its cost.

Attacking Beacon-Enabled 802.15.4 Networks
The IEEE 802.15.4 standard has attracted time-critical applications in wireless sensor networks (WSNs) because of its beaconenabled mode and guaranteed time slots (GTSs). However, the GTS management scheme’s built-in security mechanisms still leave the 802.15.4 MAC vulnerable to attacks. Further, the existing techniques in the literature for securing 802.15.4 either focus on non beacon-enabled ...
متن کاملDifferential Dynamic Traffic Control for IEEE 802.15.4 Networks
IEEE 802.15.4 provides beacon enabled and non-beacon enabled modes. Beacon enabled mode is generally used for energy efficiency. However, the main problem of beacon enabled mode is the fixed superframe structure that leads to inefficient transmission in dynamic traffic conditions. Moreover, 802.15.4 does not provide differential service according to traffic types. In this paper, we propose a Di...
متن کاملPerformance Analysis of Beacon Enabled IEEE 802.15.4 Using GTS in Zigbee
The current IEEE 802.15.4 standard restricts the beacon enabled approach to star networks, while they support multi-hop networking in mesh but with no synchronization. In this paper there is proposal of a distributed IEEE802.15.4 MAC modification to improve GTS usability in cluster networks. Location of BOP in inactive period with Virtual GTS is proposed and throughput is observed for chain top...

The IEEE 802.15.4 standard provides the widely accepted solution for low-cost and low-power wireless communications. Despite its design support for low duty-cycle operation, the fixed superframe size in Beacon-enabled mode limits its capabilities due to two contrasting goals; energy efficiency and higher data throughput. In this paper, we propose an enhancement of IEEE 802.15.4 Beacon-enabled m...
