Edge clouds are an attractive platform to support latency-sensitive applications by providing computations on servers deployed close to end-users. These servers aim to employ MPTCP to leverage multiple connections including wireless over a public network. In this paper, we show that the default MPTCP design does not adequately support reliability in these environments, which makes it unfit for use in edge clouds. We propose RAMPTCP, an extension to MPTCP which focuses on adding reliability over network paths.

Push notifications have become a prevalent way of communication for user devices to receive updates about their online profiles. State-of-the-art mechanisms for push notification delivery do not take users' spatio-temporal context into account as it would require a user device to retrieve the location and deliver it to the app servers, both of which are costly in terms of energy and traffic. In this paper, we provide an opportunistic, local, network-centric mechanism, WiPush, to deliver contextual notifications, leveraging the high density of WiFi access points (AP). WiPush does not require association with APs and uses WiFi public action frames to deliver notifications without abusing the underlying standards. Our evaluation shows that while WiPush can deliver short notifications to the users with high reliability without affecting the networking functionalities of the AP adversely, it can not be used to transfer large volumes of data.

According to an estimate several billion smart devices will be connected to the Internet by year 2020. This exponential increase in devices is a challenge to the current Internet architecture, where connectivity is based on host-to-host communication. Information-Centric Networking is a novel networking paradigm in which data is addressed by its name instead of location. Several ICN architecture proposals have emerged from research communities to address challenges introduced by the current Internet Protocol (IP) regarding e.g. scalability. Content-Centric Networking (CCN) is one of the proposals. In this paper we present a way to use CCN in an Internet of Things (IoT) context. We quantify the benefits from hierarchical content naming, transparent in-network caching and other information-centric networking characteristics in a sensor environment. As a proof of concept we implemented a presentation bridge for a home automation system that provides services to the network through CCN.

Content-Centric Network (CCN) shifts the Internet from point-to-point paradigm to receiver-driven data-centric paradigm. While it tries to solve many problems in the current Internet and opens the door to many novel applications, it also leaves many challenges unanswered, e.g., mobility support and mobile content publishing and dissemination. In this paper, we show how a greedy routing can be implemented in CCN architecture to support mobility. This allows for efficient content publisher mobility and supports seamless handoffs for interactive connections. We present our solution - MobiCCN, and evaluate it thoroughly in realistic network topologies to show it outperforms other popular mobility schemes.
