Abstract
Securing the routing process against attacks in wireless sensor network (WSN) is a vital factor to ensure the reliability of the network. In the existing system, a secure attack resilient routing for WSN using zone-based topology is proposed against message drops, message tampering and flooding attacks. The secure attack resilient routing provides a protection against attacks by skipping the routing towards less secure zones. However, the existing work did not consider the detection and isolation of the malicious nodes in the zone based wireless sensor network. To solve this issue, we proposed enhanced attack resilient routing by detecting malicious zones and isolating the malicious nodes. We proposed a three-tire framework by adopting sequential probability test to detect and isolate malicious nodes. Attacker information is shared in a secure manner in the network, so that routing selection decision can be made locally in addition to attack resiliency route selection provided at the sink. Overhearing rate is calculated for all nodes in each zone to detect blackhole attackers. Simulation results shows that the proposed Three Tier Frame work provides more security, reduced network overhead and improved Packet delivery ratio in WSNs by comparing with the existing works.
Highlights
Wireless sensor network (WSN) technology is growing rapidly in many emerging sectors such as industry monitoring and control, home surveillance, wild life monitoring and smart farming
Time required for attacker detection, False positives, Network overhead and Accuracy of detection is measured for performance analysis
The rationale for measuring the packet delivery ratio is to measure the resilience of the packet transmission in the network in presence of message dropping attacks
Summary
Wireless sensor network (WSN) technology is growing rapidly in many emerging sectors such as industry monitoring and control, home surveillance, wild life monitoring and smart farming. Due to unattended nature and wireless infrastructure, the sensor network is susceptible to various kinds of attacks like message dropping, message tampering, message flooding etc. These attacks must be detected and mitigated to ensure the reliability of the sensor networks. In [1] a secure attack resilient routing protocol is proposed to secure the routing process against possible attacks such as message dropping, message tampering and flooding. Monitoring node shares the information about the message dropping and message tampering attackers to the sink in a secure way, so that sink can skip these routes while processing the packet for routing.
