Carrier Sense Random Packet CDMA Protocol in Dual-Channel Networks [PDF]

open access: yes, 2015
Code resource wastage is caused by the reason that many hopping frequency (FH) sequences are unused, which occurs under the condition that the number of the actual subnets needed for the tactical network is far smaller than the networking capacity of ...

Anti-jamming Wireless Sensor Network Model

open access: yesInternational Journal of Circuits, Systems and Signal Processing, 2022
A wireless sensor network (WSN) of a tree-like topology is considered, which performs measurements and transmits their results to the consumer. Under the interference influence, the WSN nodes transmitters low power makes the transmitted information vulnerable, which leads to significant data loss.

Survey on cognitive anti‐jamming communications [PDF]

open access: yesIET Communications, 2020
In this study, the authors review various jamming and anti‐jamming strategies in the context of cognitive radios (CRs). The study explores different jamming models and classifies them according to their functionality. Furthermore, a study of jamming detection techniques is provided to enable a CR to identify different jamming signals.
