Abstract [en]

This paper presents an outdoor IoT-based air quality monitoring testbed deployed in the city of Uppsala, Sweden. Our IoT sensing unit is designed and developed using low-cost hardware components and open source software, which makes it easy to replicate. We demonstrate that it can serve as an affordable solution for real-time measurements and has potentials to complement traditional monitoring to cover larger areas. We use low-power communication based on IEEE 802.15.4, RPL, and MQTT, and achieve high end-to-end delivery ratio (>98%) in an outdoor setting. Moreover, we carry out network analysis of our testbed and provide detailed insights into its characteristics.

Abstract [en]

The unprecedented growth of the Internet has brought about such an enormous impact on our daily life that it is regarded as indispensable in modern era. At the same time, the underlying Internet architecture is still underpinned by principles designed several decades ago. Although IP networking has been proven very successful, it has been considered as the cause to network ossification creating barriers to entry for new network innovations. To support new demands and requirements of the current and the future Internet, solutions for new and improved Internet architectures should be sought.

Software-defined networking (SDN), a new modularized network architecture that separates the control plane from the data plane, has emerged as a promising candidate for the future Internet. SDN can be described as flow-based networking, which provides finer granularity while maintaining backward compatibility with traditional IP networking.

In this work, our goal is to investigate how to incorporate flow-based networking into open router platforms in an SDN context. We investigate performance and reliability aspects related to SDN data plane operation in software on open source PC-based routers.

Our research methodology is based on design, implementation, and experimental evaluation. The experimental platform consists of PC-based routers running open source software in combination with commodity-off-the-shelf (COTS) hardware components. When it comes to performance aspects, we demonstrate that by offloading the lookup from a CPU to a network interface card, the overall performance is improved significantly. For enhanced reliability, we investigate bidirectional forwarding detection (BFD) as a component to realize redundancy with fast failover. We demonstrate that BFD becomes unreliable under high traffic load and propose a solution to this problem by allocating dedicated system resources for BFD control messages. In line with this solution, we extend our architecture for next-generation PC-based routers with OpenFlow support by devising a strategy to efficiently map packet forwarding and application processing tasks onto the multi-core architecture on the PC-based router. This extension would make it possible to integrate BFD effectively into the router platform.

Our work demonstrates the potentials of open router platforms for SDN. Our prototypes offer not only high performance with good reliability but also flexibility to adopt new software extensions. Such platforms will play a vital role in advancing towards the future Internet.

Abstract [en]

Doctor shortage is a universal problem. Technologies can be used to address the issue by extending the healthcare services over the data network to virtually anywhere. In this paper, we propose Carenet architecture to extend healthcare services to the home of a patient in a robust, secure, and cost-effective manner. The prototype architecture is developed using a residential gateway (RG). The RG is built using open source software on Commodity-Off-The-Shelf (COTS) hardware. It uses low-power components with multiple power sources to provide robustness. The healthcare services are offered over a private overlay network. Linux containers are used to provide service isolation on the RG. The data is encrypted at the application level for each service to ensure confidentiality. Resilient communication is realized based on physical redundant links from two Internet connections from different ISPs. The failover time within sub-seconds time frame is achieved using our prototype RG.

Abstract [en]

In line with the shift towards renewable energy, small-scale solar panels have become commonly available. Solar panels are intermittent energy sources producing direct current, and DC-DC converters are needed to convert between different voltage levels, both for different power loads and for storing energy. DC-DC converters typically have a very limited functionality and are statically configured for specific voltage levels. In this paper, we propose a new generation of flexible DC-DC converters with software and communication support (through Contiki and CoAP) for remote power monitoring and control. We present a prototype design and implementation of a DC-DC converter including a microprocessor, a lean operating system, and networking support. With such a DC-DC converter, controlled over the Internet, we can address various types of power and energy related issues and advance the state-of-the-art of green networked applications.

Abstract [en]

Advancements in today's technologies make it possible to offer competitive home-based healthcare services using software routers based on open source software combined with Commodity-Off-The-Shelf (COTS) hardware. In this paper, we propose resilient communication through multihoming for remote healthcare applications. The solution is based on Bidirectional Forwarding Detection (BFD) for fast failure detection and a customized rerouting operation. We investigate the tradeoff between short reaction times for rerouting and low probability of false alarms. This is challenging to achieve under high traffic loads since the load affects the BFD session which is formed to monitor the bidirectional forwarding capabilities. We propose a simple mechanism that provides fast failover and meanwhile maintains a very low probability of generating false alarms and unwanted rerouting decisions. The mechanism is based on allocation of system resources for processing BFD control messages, and we demonstrate through empirical results that BFD then can be used in software routers to provide average failover times within 200 ms.

Abstract [en]

The increased capacity needs, primarily driven by content distribution, and the vision of Internet-of-Things with billions of connected devices pose radically new demands on future wireless and mobile systems. In general the increased diversity and scale result in complex resource management and optimization problems in both radio access networks and the wired core network infrastructure. We summarize results in this area from a collaborative Sino-Swedish project within IMT Advanced and Beyond, covering adaptive radio resource management, energy-aware routing, Open Flow-based network virtualization, data center networking, and access network caching for TV on demand.

Abstract [en]

Energy efficiency has gained interests in the research community over the recent years thanks to the rising concerns around the globe for the greener future.With the increasing electricity price, there is also a strong economic incentive to make the network infrastructure more energy-efficient.Traditionally, the fixed network infrastructures are built with the mindset to deliver high performance and availability resulting in power-demanding network infrastructures.This paper summarizes the work done so far in the area of energy efficiency in fixed network infrastructures. We define the taxonomy of these approaches to be node level, link level, and network-wide level and give an overview of the key techniques in each category.

Abstract [en]

A modern PC-based router can provide as competitive service as a specialized hardware router while offering more flexibility and possibility to extend beyond routing. We focus on a use case in which the PC-based router also functions as a server. In this paper, we propose a multi-core based architecture for a combined router/server that efficiently provides simultaneous packet forwarding and server processing. We improve the overall performance by creating a fast path for packet forwarding through caching flow entries in on-board classification hardware on the NIC. We propose a generic design based on multi-core processors and multi-queue network interface cards. We describe a prototype implementation and present an experimental evaluation of this design. We also devise a strategy for how to efficiently map packet forwarding and application processing tasks onto the multi-core architecture.

In this paper, we propose an architecture to boost overall performance of the PC-based router by offloading packet processing tasks to the NIC.
