Abstract EN
The Internet of Things (IoT) is the interconnection of different objects through the internet using different communication technologies.
The objects are equipped with sensors and communications modules.
The cognitive radio network is a key technique for the IoT and can effectively address spectrum-related issues for IoT applications.
In our paper, a novel method for IoT sensor networks is proposed to obtain the optimal positions of secondary information gathering stations (SIGSs) and to select the optimal operating channel.
Our objective is to maximize secondary system capacity while protecting the primary system.
In addition, we propose an appearance probability matrix for secondary IoT devices (SIDs) to maximize the supportable number of SIDs that can be installed in a car, in wearable devices, or for other monitoring devices, based on optimal deployment and probability.
We derive fitness functions based on the above objectives and also consider signal to interference-plus-noise ratio (SINR) and position constraints.
The particle swarm optimization (PSO) technique is used to find the best position and operating channel for the SIGSs.
In a simulation study, the performance of the proposed method is evaluated and compared with a random resources allocation algorithm (parts of this paper were presented at the ICTC2017 conference (Wen et al., 2017)).
