【摘要】：针对如何有效利用多个资源提供者为请求资源的车辆提供服务的问题,引入车辆服务能力的概念,面向城市车辆自组织网络(VANET)环境,提出了一种车联网协同服务发现中间件体系结构.该中间件可以根据车辆的内部资源和自身的物理属性,综合衡量其提供服务的能力.同时,设计了协同服务发现算法,将服务任务根据提供服务车辆的服务能力进行合理分配.计算可提供服务车辆的服务能力和协同服务车辆阈值,确定服务提供者列表.按照列表内各车辆的服务能力,将请求的服务任务进行分配,并将服务请求车辆与服务提供者进行服务绑定.仿真结果表明,与相同城市环境下的VITP算法相比,所提算法可降低服务绑定时间,并提高服务绑定成功率.
[Abstract]:In order to solve the problem of how to effectively utilize multiple resource providers to provide services for vehicles requesting resources, the concept of vehicle service capability is introduced to face the (VANET) environment of urban vehicle ad hoc networks. This paper presents a middleware architecture for collaborative service discovery in vehicle networking. The middleware can comprehensively measure the ability of the vehicle to provide services according to its internal resources and its own physical properties. At the same time, a collaborative service discovery algorithm is designed to distribute the service tasks according to the service capacity of service vehicles. The service capacity and collaborative service vehicle threshold are calculated to determine the list of service providers. According to the service capacity of each vehicle in the list, the requested service task is assigned and the service request vehicle is bound to the service provider. The simulation results show that compared with the VITP algorithm in the same urban environment, the proposed algorithm can reduce the service binding time and improve the success rate of service binding.
