Efficient Channel Access Model for Detecting Reactive Jamming for Underwater Wireless Sensor Network

Underwater sensor networks (UWSNs) are exposed to various kind of wireless jamming attacks such as reactive, optimal, proactive, and hybrid jammer. Among jamming attack, reactive jammer has been a biggest security concern for UWSN. This is due to its significant impact to authenticated sensor device communication. Along with, it is difficult to be disclosed and defended. A reactive jammer preserve high vulnerability with low detection likelihood by regulating jamming duration (i.e., jamming probability) of jamming signal. The state-of-work presented so far for detecting reactive jammer are designed considering terrestrial wireless sensor networks (TWSNs). Further, a very limited work is carried out using cooperative jamming detection in UWSN. For overcoming research challenges, this work present Efficient Channel Access (ECA) model using cross layer design for mitigating reactive jammer. The ECA jointly optimizes the cooperative hopping probabilities and channel accessibility probabilities of authenticated sensor device. Experiment outcome shows the proposed ECA model attain superior performance than state-of-art model in terms of packet transmission.
