基于REST风格的混杂感知车载网信息服务设计

实时可靠地获得全面的车载感知服务信息是车载网络发展的"瓶颈"问题。混杂感知车载网(HSVN)兼有无线传感器网络(WSN)和车载自组网(VANET)的特点,为车载用户提供了大量车载信息,是车载网络的发展趋势。表述性状态转移(REST)架构统一了资源格式和交互形式,在服务器和客户端间进行无状态服务,有利于异构问题的解决。文章基于HSVN的信息服务特征,提出一种新型车载网络框架和服务模型,能提高车载感知信息的服务交互能力;基于REST架构理念,采用HSVN中信息服务资源设计方法,为异构网络下的信息交互系统提供一种轻量化的实现途径。

Design of a RESTful Service for Hybrid Sensor and Vehicular Networks

Obtaining vehicular sensor information reliably in real time has always been a bottleneck in vehicular networks. Hybrid sensor and vehicular networks (HSVN) incorporates the features of wireless sensor networks (WSN) and vehicular ad hoc networks (VANET) and provides users with a large amount of vehicular information. HSVN is becoming the trend in vehicular network development. REST architecture makes resources and interactive behavior more uniform and creates stateless services between server and client. These features are helpful for heterogeneous applications. In this paper, we propose a new vehicular network frame and service module for improving interaction. We propose a way of using the information service resources design method in HSVN to create a lightweight method for building an interactive system in a heterogeneous network environment.
