【摘要】 在蓝牙散射网中,由于多个蓝牙微微网共存,导致信息传输的冲突问题越来越严重。基于网络间距离对蓝牙信息包在网络中传输进行了建模,从而研究多蓝牙微微网共存时的干扰问题。早期研究方法没有考虑网络间的距离,基于网络间距离对此问题进行了深入分析,通过大量仿真,得出新的蓝牙微微网间的干扰分析公式,进而得出新的网络误包率和网络吞吐量等系统参数的变化规律。更多还原

【Abstract】 Working in the unlicensed 2.4 GHz ISM band,a Bluetooth piconet will encounter interference and collision problems from other piconets.With a special channel model and packet format based on distance,we focus on how the interference and collision change with the number of piconets and the loads.In earlier works,the related problems have been studied,but they didn’t take distance into consideration.By taking this factor into consideration,the result drawn through simulating shows that how the network changes not only with piconet numbers and loads but also the distance of the network area.更多还原
