Mobile agent-based cross-layer anomaly detection in smart home sensor networks using fuzzy logic

Abstract

Despite the rapid advancements in consumer electronics, the data transmitted by sensing devices in a smart home environment are still vulnerable to anomalies due to node faults, transmission errors, or attacks. This affects the reliability of the received sensed data and may lead to the incorrect decision making at both local (i.e., smart home) and global (i.e., smart city) levels. This study introduces a novel mobile agent-based cross-layer anomaly detection scheme, which takes into account stochastic variability in cross-layer data obtained from received data packets, and defines fuzzy logic-based soft boundaries to characterize behavior of sensor nodes. This cross-layer design approach empowers the proposed scheme to detect both node and link anomalies, and also effectively transmits mobile agents by considering the communication link-state before transmission of the mobile agent. The proposed scheme is implemented on a real testbed and a modular application software is developed to manage the anomaly detection system in the smart home. The experimental results show that the proposed scheme detects cross-layer anomalies with high accuracy and considerably reduces the energy consumption caused by the mobile agent transmission in the poor communication link-state situations 1 .

“…After learning, the reasoning module determines which service to provide by observing the user behaviors and the environment up to the decision making point. The learning and reasoning algorithms reported in the literature include the rule-based system [13], hidden Markov model (HMM) [14]- [16], computational intelligence (CI) [17]- [20], and reinforcement learning (RL) [21]- [23]. Rule-based algorithms encode expert knowledge and use the engineered knowledge to reason services for given situations.…”
