Route Planning for Mobile IoT Devices

摘要

For mobile IoT devices like mobile collectors gathering data from fixed IoT sensors optimal route planning between two geographical points is essential not only with respect to the length, the traceability, the duration or the economy of the route but especially for bandwidth-demanding applications, the spectrum availability along route. Our scope is the improvement of spectrum exploitation by optimal route selection for moving cognitive IoT devices utilizing TV white space. We investigate the applicability of our proposed new route planning aspects of mobile IoT devices applying cognitive radio technology in TV white space environment. The primary users are in this scenario fixed receivers in the TV UHF band, while the moving secondary users are trying to use the same spectrum in the TV white space without disturbing the primary service and achieve as high data rate as possible. To fulfil the latter condition, an adaptive modulation mode selection algorithm will be also shown. Two different propagation areas, rural and urban have been selected for simulations and calculations.
