以信息为中心的网络（ICN）最吸引人的功能之一是其基于消费者请求和逐跳转发的敏捷无连接传输模型。通过放松端到端的约束，ICN授权的分布式网络控制的潜力，以改善拥塞管理异构有线/无线媒体和存在的移动性。然而，迄今为止，很少有人致力于探索国际竞争网络在这一领域的能力。在本文中，我们有助于ICN在无线移动的网络控制的机会和一个简单的，但非常有效的机制，在网络丢失检测和恢复，以补充接收器驱动的控制的建议。更准确地说，我们引入了（i）WLDR，一种网络内无线丢失检测和恢复机制，可以及时识别和恢复无线接入点的信道丢失;（ii）MLDR，一种通过显式网络通知和动态请求重新路由来防止由于消费者/生产者移动性而造成的损失的机制。我们在ndn-SIM中使用IEEE 802.11n连接建立了一个真实的无线仿真环境，并评估了WLDR-MLDR的性能。结果显示，无论是否有明确的丢失通知，基于消费者的解决方案都具有显着的优势，同时还消除了对网络和应用程序计时器的任何依赖。
One of the most appealing features of Information-Centric Networking (ICN) is its agile connectionless transport model based on consumer requests and hop-by-hop forwarding. By relaxing end-to-end constraints, ICN empowers a distributed in-network control with the potential to improve congestion management over heterogeneous wired/wireless media and in presence of mobility. However, little effort has been devoted so far to the exploration of ICN capabilities in this space. In this paper, we contribute an understanding of the opportunities for ICN in-network control over wireless mobile networks and a proposal for simple, yet very effective mechanisms for in-network loss detection and recovery to complement receiver-driven control. More precisely, we introduce (i) WLDR, a mechanism for in-network Wireless Loss Detection and Recovery that promptly identifies and recovers channel losses at wireless access point and (ii) MLDR, a mechanism for preventing losses due to consumer/producer mobility via explicit network notification and dynamic on-the-fly request re-routing. We setup a realistic wireless simulation environment in ndn-SIM using IEEE 802.11n connectivity and evaluate WLDR-MLDR performance. The results show significant benefits over consumer-based solutions with or without explicit loss notification, while also removing any dependency from network and application timers.
