【摘要】：針對如何有效利用多個資源提供者為請求資源的車輛提供服務的問題,引入車輛服務能力的概念,面向城市車輛自組織網絡(VANET)環(huán)境,提出了一種車聯(lián)網協(xié)同服務發(fā)現(xiàn)中間件體系結構.該中間件可以根據(jù)車輛的內部資源和自身的物理屬性,綜合衡量其提供服務的能力.同時,設計了協(xié)同服務發(fā)現(xiàn)算法,將服務任務根據(jù)提供服務車輛的服務能力進行合理分配.計算可提供服務車輛的服務能力和協(xié)同服務車輛閾值,確定服務提供者列表.按照列表內各車輛的服務能力,將請求的服務任務進行分配,并將服務請求車輛與服務提供者進行服務綁定.仿真結果表明,與相同城市環(huán)境下的VITP算法相比,所提算法可降低服務綁定時間,并提高服務綁定成功率.
[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.
