在分布式實(shí)時(shí)嵌入式系統(tǒng)（DRMS）中，維持端到端（end-to-end）的服務(wù)質(zhì)量（quality
of service，QoS）是一項(xiàng)富有挑戰(zhàn)性的任務(wù)。本文提出了一種基于中間件的端到端QoS 管理模型，并通過(guò)此模型在“近海水面大區(qū)域智能自動(dòng)游動(dòng)式監(jiān)測(cè)站系統(tǒng)”中的應(yīng)用，展示了端到端資源管理模型是如何動(dòng)態(tài)重配置系統(tǒng)，以滿足實(shí)時(shí)QoS 需求的。

Abstract: Maintaining end-to-end quality of service (QoS) is a challenge in distributed real-time embedded systems (DRMS). This paper presents a middleware-based end-to-end QoS
management model for DRMS and a case study of “intelligent automatic roving monitor system for large area of coastal waters” to show how end-to-end resource management techniques are used to reconfigure the system dynamically to meet real-time QoS requirements.
