Abstract
Resource bound security solutions have facilitated the mitigation of spatio-temporal attacks by altering protocol semantics to provide minimal security while maintaining an acceptable level of performance. The Dynamic Window Secured Implicit Geographic Forwarding (DWSIGF) routing protocol for Wireless Sensor Network (WSN) has been proposed to achieve a minimal selection of malicious nodes by introducing a dynamic collection window period to the protocol’s semantics. However, its selection scheme suffers substantial packet losses due to the utilization of a single distance based parameter for node selection. In this paper, we propose a Fuzzy-based Geographic Forwarding protocol (FuGeF) to minimize packet loss, while maintaining performance. The FuGeF utilizes a new form of dynamism and introduces three selection parameters: remaining energy, connectivity cost, and progressive distance, as well as a Fuzzy Logic System (FLS) for node selection. These introduced mechanisms ensure the appropriate selection of a non-malicious node. Extensive simulation experiments have been conducted to evaluate the performance of the proposed FuGeF protocol as compared to DWSIGF variants. The simulation results show that the proposed FuGeF outperforms the two DWSIGF variants (DWSIGF-P and DWSIGF-R) in terms of packet delivery.
Highlights
Routing and security are two of the most prominent research challenges in Wireless Sensor Network (WSN) that have gained much ground, due to the emergence of Cyber-Physical Systems (CPS) and Internet of Things (IoT)that employ sensor devices for communication
Rushing a CTS signal by the attacker is often presumed to be successful as the timing lacks fixed interval for collection to begin
In an effort to mitigate the effect of spatio-temporal attacks on a network, resource bound security solution suggested altering protocol semantics or installing mechanisms that would prevent the selection of malicious entity as well as maintain base performance of the protocol
Summary
Routing and security are two of the most prominent research challenges in WSN that have gained much ground, due to the emergence of Cyber-Physical Systems (CPS) and Internet of Things (IoT). Several security approaches used by routing protocols are inefficient in mitigating spatio-temporal attacks This is because of the high resource consumption of the pertinent mechanisms employed for the security solutions on the sensor node. Sensors 2016, 16, 943 performance while minimizing security threats using minimal resource consumption [2] This solution was proven successful in [2] and has been applied to various routing protocols in [2,3,4] to mitigate spatio-temporal attacks. The utilization of a distance based parameter (only) for forwarding node selection in the network has simplified spatio-temporal predictions, causing strategic placement of malicious nodes to succeed in enabling substantial packet losses in the network. Performance evaluations of the base and proposed protocol were discussed in Sections 5 and 6 presents the conclusion and future works
