Building a transparent optical wide area network with multipaths
Journal of optical communications and networking, 2013Co-Authors: Davide Cuda, Esther Le Rouzic, Raluca-maria Indre, James RobertsAbstract:We propose an all-optical networking solution for a wide area network built on shared multipoint-to-multipoint lightpaths that, for short, we call “multipaths.” A multipath concentrates the traffic of a group of source nodes on a wavelength channel using an adapted medium access control protocol and multicasts this traffic to a group of destination nodes that extract their own data from the confluent stream. The proposed network can be built using existing components and appears less complex and more efficient in terms of energy consumption than alternatives like optical packet switching and optical burst switching. The paper presents the multipath architecture and compares its energy consumption to that of a classical router-based Internet service provider network. A flow-aware dynamic bandwidth allocation algorithm is proposed and shown to have excellent performance in terms of throughput and delay.

Getting routers out of the core: Building an optical wide area network with "multipaths
2012Co-Authors: Davide Cuda, Esther Le Rouzic, Raluca-maria Indre, James RobertsAbstract:We propose an all-optical networking solution for a wide area network (WAN) based on the notion of multipoint-to-multipoint lightpaths that, for short, we call "multipaths". A multipath concentrates the traffic of a group of source nodes on a wavelength channel using an adapted MAC protocol and multicasts this traffic to a group of destination nodes that extract their own data from the confluent stream. The proposed network can be built using existing components and appears less complex and more efficient in terms of energy consumption than alternatives like OPS and OBS. The paper presents the multipath architecture and compares its energy consumption to that of a classical router-based ISP network. A flow-aware dynamic bandwidth allocation algorithm is proposed and shown to have excellent performance in terms of throughput and delay.

Low Power wide area network Analysis: Can LoRa Scale?
IEEE Wireless Communications Letters, 2017Co-Authors: Orestis Georgiou, Usman RazaAbstract:Low Power wide area (LPWA) networks are making spectacular progress from design, standardisation, to commercialisation. At this time of fast-paced adoption, it is of utmost importance to analyse how well these technologies will scale as the number of devices connected to the Internet of Things (IoT) inevitably grows. In this letter, we provide a stochastic geometry framework for modelling the performance of a single gateway LoRa network, a leading LPWA technology. Our analysis formulates unique peculiarities of LoRa, including its chirp spread-spectrum modulation technique, regulatory limitations on radio duty cycle, and use of ALOHA protocol on top, all of which are not as common in today's commercial cellular networks. We show that the coverage probability drops exponentially as the number of end-devices grows due to interfering signals using the same spreading sequence. We conclude that this fundamental limiting factor is perhaps more significant towards LoRa scalability than for instance spectrum restrictions. Our derivations for co-spreading factor interference found in LoRa networks enables rigorous scalability analysis of such networks.
