物联网距离和业务特征结合的频谱接入方法
Opportunistic spectrum accessing joint distance with service characteristics in IOT networks
摘要
Abstract
An accessing scheme which combines distance with service for the applications in IOT networks was proposed. First, a channel-availability list based on the distance relationship between system and non-system users was built. The list provided a priority of each channel for non-system users. Then the service-matched expression between the IOT user and the liscensed user was proposed. Based on the list and the expression, a interfrence-driven utility function was defined. Finally, the accessing scheme was optimized from the cross-layer design point of view. It was proved that the scheme guaranteed both the interference suppression and the resource sharing in IOT based on the QoS requirements.关键词
