The pervasiveness of the communication networks increasingly has made possible to interconnect software‐intensive systems that were independently developed, operated, managed, and evolved, yielding a new kind of complex system, that is, a system that is itself composed of systems, the so‐called System‐of‐Systems (SoS). Nowadays, the Internet‐of‐Things (IoT) enables the engineering of software‐intensive SoS, which are opportunistically constructed for achieving specified missions in specific operational environments. In particular, in the subset of IoT where “things” are predominantly connected vehicles, the so‐called Internet‐of‐Vehicles (IoV), the challenge is to exogenously coordinate different vehicles for performing together, through emergent behavior, traffic‐related missions, especially platooning. In platooning, two or more vehicles are connected together in convoy using wireless connectivity and automated driving support. The corresponding challenge in the architectural design of SoSs on IoV is to conceive concepts and mechanisms for describing how an SoS architecture is able to create, on the fly, and maintain emergent behaviors from elementary connected vehicles, where the actual vehicles are not known at design time. To address this challenge, this paper investigates the principle of supervenience for describing architecture‐driven emergent behavior following an exogenous approach. In particular, it describes the concepts and mechanisms underlying SosADL, a formal SoS Architecture Description Language (ADL), based on the novel π‐Calculus for SoS, to support the architectural description of self‐organizing SoSs, upwardly causing the required SoS emergent behaviors at run time. Especially, it demonstrates how architectural mediators expressed with SosADL in exogenous SoS architectures support vehicle platooning through an excerpt of a real application on the IoV.

使用SosADL在车载互联网上构建外源软件密集型系统

通信网络的普遍性日益使互连独立开发,操作,管理和演进的软件密集型系统成为可能,从而产生了一种新型的复杂系统,即,一个系统本身由系统组成,因此称为系统系统(SoS)。如今,物联网(IoT)启用了软件密集型SoS的工程设计,该软件是根据机会构建的,目的是在特定的操作环境中实现指定的任务。特别是在物联网主要是“物联网”的物联网子集中,即所谓的车联网(IoV),挑战在于通过突发行为,与交通有关的任务,外生地协调不同的车辆以共同执行,尤其是排。在排,使用无线连接和自动驾驶支持,两个或两个以上的车辆在车队中连接在一起。IoV上的SoS的架构设计中的相应挑战是构想概念和机制,以描述SoS架构如何能够动态创建和维护基本互联车辆的突发行为,而实际车辆在设计时尚不知道时间。为了应对这一挑战,本文研究了一种外在方法,它描述了由架构驱动的紧急行为的超级原理。特别是,它描述了SosADL(一种正式的SoS架构描述语言(ADL))的概念和机制,该框架基于新颖的π-Salculusfor SoS,以支持自组织SoS的架构描述,在运行时向上导致所需的SoS紧急行为。尤其是,它演示了在外源SoS架构中用SosADL表达的架构中介如何通过在IoV上的实际应用摘录来支持车辆排。
