摘要:

针对车联网环境下车辆内部的终端进行网络共享和接入外部网络的问题,研制了一种无线接入多模网关,该网关能够在车辆内部组建无线局域网,并实现将无线局域网内的设备接入到公众移动通信网络(例如3G/4G)和互联网。首先给出系统的总体结构,然后对无线多模网关的硬件平台和应用软件的设计开发进行详细论述,研究了无线接入网络的选择策略,针对不同的业务分类利用层次分析法获得相应权重分配以达到最优的网络性能。实验结果表明所研制的网关完全达到了设计要求。

Abstract:

A wireless access multimode gateway system was developed in order to solve the problems of the network share and external network access for wireless devices equipped in the cars to form the internet of vehicle(IoV). By the gateway system, the wireless local area network(WLAN)can be established. The terminals within this WLAN can access the public mobile communication network such as 3G even 4G and external internet in the vehicles. First, the system architecture was given. Then, the design and development of the wireless access multimode gateway were described in detail including the hardware platform and application software. Meanwhile, the selection strategy of wireless access network was studied according to the different business classifications to obtain the corresponding weight distribution by using analytic hierarchy process, in order to achieve the optimum network performance. The test results show that the developed gateway accords with the design requests and has the reliable and stable performances.

Key words: wireless access, multimode gateway, internet of vehicle, wireless local area network, public mobile communication network, network selection
