认知无线电中基于数据冲突的吞吐量和感知周期均衡
Throughput Trade-off with Sensing Period Based on Data Collisions in Cognitive Radios
摘要
Abstract
There are inevitable data collisions between the primary and cognitive users. There is a trade-off between the sensing period and the system throughput. This paper models the data collision based on the exponential on/off data traffic model and the periodic frame structure of the cognitive radios. The sensing period is optimized and the trade-off between the throughput and the sensing period is achieved with a low probability of the data collision. The results are validated by Monte Carlo simulations.关键词
