基于停放车辆的互联网接入研究

在当下移动互联网无时无处不在的环境中,人们随时随地希望能够以较高的带宽连接到互联网.但当人们在行驶的车辆中时,却只能通过2G/3G连接到网络,并且这些连接能够提供的带宽非常有限,这时我们需要一个在车辆中也可提供较大带宽的网络连接.车载网络技术使智能交通通信方面得到较大的发展,通过智能交通中的车载网络节点和路边基础设施构成的自组织网络可以实现车辆与车辆之间,车辆与路边无线接入点之间的相互通信.本文研究的就是基于上述情况下一种新型的基于停放车辆的互联网接入系统.这个系统保证了移动车辆在最小的带宽存在下,短时间与互联网络进行信息的交互,它能够以某个停放车辆作为中继发散网络的接入点,充当网络的前沿基站.在信息获取到后通过其本身固定的与室内接入的连接,将信息发送到网络上,当车到达下一个可接入点时,返回之前提交休息的应答.这样的研究有助于解决未来的移动车辆的全网络覆盖与交互问题.

Internet access based on parking vehicles

Internet may be accessed whenever and anytime currently. but users hope for a superior bandwidth for internet accessing.Besides,on moving vehicles the internet can only be accessed via 2G/3G with limited bandwidth . Therefore, internet access with wider bandwidth on moving vehicles is the priority. VANET makes a great contribution to intelligent transportation communication. Information between vehicles or between vehicle and roadside AP can be communicated via Ad-hoc networks which consist of on-board network nodes and roadside infrastructures. This article describes the case of a new type of internet access based on parking vehicles. This system ensures information connection in short time with minimum bandwidth among vehicles. It allows a parking vehicle to be the access point, acting as a leading base station. After receiving information it may send packages to networks by connection with indoor accesses. After reaching the next access point, it would back on submitted response. The research contributes to FMWC and connections among vehicles.
