The document discusses various Internet of Things (IoT) networking technologies and their capabilities. It introduces DASH7 as an IoT networking standard that aims to provide a better overall IoT stack compared to other technologies. DASH7 claims to be phy agnostic, support dynamic MAC layers, IPv6 compatible networking, a universal filesystem, query-driven sessions, and standardized application support. It also aims to provide ultra low power capabilities, long ranges, low latency, and other features through its technical design and use of technologies like LoRa radios and error correction.
Recently published research (July 2019) has described a model for Bit Error Rate (BER) analysis of the LoRa PHY over a Rayleigh flat fading channel. Rayleigh flat fading channels are observable in environments where there’s a lot of multipath interference (e.g. dense urban, indoor, etc).
The LoRa PHY experiences significant degradation of sensitivity in Raleigh flat fading channels
Experimentation in an environment exhibiting Raleigh flat fading validates the model from the research.
Haystack XR2 encoding for LoRa was observed to yield roughly 30 dB gain to Packet Error Rate (PER) vs. default LoRaWAN encoding, in said experiment.
Haystack XR2 encoding for LoRa can yield enormous gains to efficiency, Quality of Service (QoS), and channel density for LoRa deployments in dense urban, indoor, or other environments where multipath dominates.
Haystack's new hardware for Semtech's LoRa includes on-demand GPS, up to 36 mile range, 3-5 year battery life, and no subscriptions. Demo kits now available.
Wireless IoT connections fall into two low-power camps: local area and wide area. Historically the two have not overlapped but advances in networking technologies make it possible for wide area technologies to perform the same functions as local area technologies with no additional cost or feature "sacrifice".
How new Low Power Wireless Area Networks (LPWAN's) are aggressively challenging the Internet of Things status quo and how industry can exploit this opportunity. Specifically, the ability to query IoT endpoints in real time, improve network capacity and data rates, and the ability to deploy a filesystem in order to create a "Hadoop"-like real-time query capability at the edge of the network is explored.
Haystack XR Mode radically improves the range of IoT devices using Semtech's LoRa radio. Using the same error correction used in deep space probes along with other techniques, Haystack offers the longest range, lowest power, and lowest latency networking stack for LoRa today.
Emerging LTE standards for IoT lack a networking stack for true real-time, low power networking. A simple add-on to the existing TCP/IP stack makes a difference.

Weightless - a new standard, a new technologyDhruvit Rajpura
It was a pleasure giving a power-point presentation on the new trending LPWAN technology i.e. the weightless standard. Weightless-p is indeed a truly open sourced technology with a definite future, specifically designed for IIOT in order to make M2M communications better.
Check out slides presented by Mo Haghighi, Research Scientist at Intel Labs Europe, which explore how to solve urban challenges at the Olympic Park. These slides were presented at Digital Catapult's LPWAN London meetup.
This presentation is based on the IETF draft draft-farrell-lpwan-lora-overview-01 and provides a brief overview of the LoRaWAN architecture. It was presented at the LPWAN WG meeting in IETF 98.
A brief summary of the LPWAN wireless protocols and a more technical overview of LoRa (Long-Range) starting from PHY and throughout the rest of the LoRaWAN stack emphasizing its implications on IoT platforms.

Overview of which LPWAN technologies (LoRa, Sigfox, Weightless, etc.) are right for various IoT applications. Clear look at the pros and cons of each technology.
Overview of Proxy Mobile IP for IPv6 mobility.
Mobile IP (MIP) allows mobile nodes to roam between networks while
keeping existing connections open thus allowing seamless operation
on application level.
However, Mobile IP requires additions to the OS kernel that make deployments
difficult if not impossible alltogether.
Proxy Mobile IPv6 (PMIPv6) allows mobility scenarios for non-MIP aware mobile nodes.
A proxy assumes all functionality required for mobile nodes to roam from
one wireless network to another. PMIPv6 achieves this with a Mobile Access Gateway
(MAG, the proxy) and a Local Mobility Anchor (LMA) that represents the single point of attachment
for corresponding nodes.
PMIPv6 is most suited for campus-type networks where all wireless networks are under
the control of a single authority.
An Overview of LoRA, Sigfox, and IEEE 802.11ahFaheem Zafari
The slides provide an insight into different IoT and M2M specific protocols. Their main features and differences are highlighted. Potential research area in IEEE 802.11ah is identified. The slides also identifies the coexistence problem between Lora and Sigfox
An experience is a personal and emotional event we remember. Every experience is established based upon pre-determined expectations we conceive and create in our minds. It’s personal, and therefore, remains a moving and evolving target in every scenario. When our experience concludes and the moment has passed, the outcome remains in our memory. Think about what makes you happy when connecting with your own device and then think about what makes you really upset when things are hard, complicated, and slow. If the user has a bad experience in anyone of these areas (simple, fast, and smart), they are likely to leave, share their negative experience, and potentially never return. Users might forget facts or details about their computing environment but they find it difficult to forgot the feeling behind a bad network experience. When something goes wrong with the network or an application, do you always get the blame?
If the number of spine switches were to be merely doubled, the effect of a single switch failure is halved. With 8 spine switches, the effect of a single switch failure only causes a 12% reduction in available bandwidth. So, in modern data centers, people build networks with anywhere from 4 to 32 spine switches. With a leaf-spine network, every server on the network is exactly the same distance away from all other servers – three port hops, to be precise. The benefit of this architecture is that you can just add more spines and leaves as you expand the cluster and you don't have to do any recabling. Intuition Systems will also get more predictable latency between the nodes.
As a trend, disaggregation seems to be most useful for very large companies like Facebook and Google, or cloud providers. The technology does not necessarily have significant implications for small or medium sized businesses. Historically, however, technology has a way of trickling down from the pioneering phases of existing only within large companies with tremendous resources, to becoming more standardized across the board.
Large venues like stadiums or concert halls are challenging environments for Wi-Fi deployments. Most of today’s phones and tablets carry Wi-Fi interfaces. A safe assumption is that at least one device per person in a stadium carry a Wi-Fi interface. Monetizing those Wi-Fi interfaces with real time information of the event in the venue, targeted advertising, internet access, multimedia and social applications can create new revenues to the owner of the venue, if executed properly.

Understanding Globus Data Transfers with NetSageGlobus
NetSage is an open privacy-aware network measurement, analysis, and visualization service designed to help end-users visualize and reason about large data transfers. NetSage traditionally has used a combination of passive measurements, including SNMP and flow data, as well as active measurements, mainly perfSONAR, to provide longitudinal network performance data visualization. It has been deployed by dozens of networks world wide, and is supported domestically by the Engagement and Performance Operations Center (EPOC), NSF #2328479. We have recently expanded the NetSage data sources to include logs for Globus data transfers, following the same privacy-preserving approach as for Flow data. Using the logs for the Texas Advanced Computing Center (TACC) as an example, this talk will walk through several different example use cases that NetSage can answer, including: Who is using Globus to share data with my institution, and what kind of performance are they able to achieve? How many transfers has Globus supported for us? Which sites are we sharing the most data with, and how is that changing over time? How is my site using Globus to move data internally, and what kind of performance do we see for those transfers? What percentage of data transfers at my institution used Globus, and how did the overall data transfer performance compare to the Globus users?
Providing Globus Services to Users of JASMIN for Environmental Data AnalysisGlobus
JASMIN is the UK’s high-performance data analysis platform for environmental science, operated by STFC on behalf of the UK Natural Environment Research Council (NERC). In addition to its role in hosting the CEDA Archive (NERC’s long-term repository for climate, atmospheric science & Earth observation data in the UK), JASMIN provides a collaborative platform to a community of around 2,000 scientists in the UK and beyond, providing nearly 400 environmental science projects with working space, compute resources and tools to facilitate their work. High-performance data transfer into and out of JASMIN has always been a key feature, with many scientists bringing model outputs from supercomputers elsewhere in the UK, to analyse against observational or other model data in the CEDA Archive. A growing number of JASMIN users are now realising the benefits of using the Globus service to provide reliable and efficient data movement and other tasks in this and other contexts. Further use cases involve long-distance (intercontinental) transfers to and from JASMIN, and collecting results from a mobile atmospheric radar system, pushing data to JASMIN via a lightweight Globus deployment. We provide details of how Globus fits into our current infrastructure, our experience of the recent migration to GCSv5.4, and of our interest in developing use of the wider ecosystem of Globus services for the benefit of our user community.

How to Position Your Globus Data Portal for Success Ten Good PracticesGlobus
Science gateways allow science and engineering communities to access shared data, software, computing services, and instruments. Science gateways have gained a lot of traction in the last twenty years, as evidenced by projects such as the Science Gateways Community Institute (SGCI) and the Center of Excellence on Science Gateways (SGX3) in the US, The Australian Research Data Commons (ARDC) and its platforms in Australia, and the projects around Virtual Research Environments in Europe. A few mature frameworks have evolved with their different strengths and foci and have been taken up by a larger community such as the Globus Data Portal, Hubzero, Tapis, and Galaxy. However, even when gateways are built on successful frameworks, they continue to face the challenges of ongoing maintenance costs and how to meet the ever-expanding needs of the community they serve with enhanced features. It is not uncommon that gateways with compelling use cases are nonetheless unable to get past the prototype phase and become a full production service, or if they do, they don't survive more than a couple of years. While there is no guaranteed pathway to success, it seems likely that for any gateway there is a need for a strong community and/or solid funding streams to create and sustain its success. With over twenty years of examples to draw from, this presentation goes into detail for ten factors common to successful and enduring gateways that effectively serve as best practices for any new or developing gateway.

13. DASH7’s Unfair Competitive Advantage
DASH7 Advertising Packets
Gateway transmits bursts of advertising packets that include a
query as well as instructions for how and when to respond.
This results in:
- Very low endpoint power consumption
- Very low latency responses between devices
- A method for quickly synchronizing large grounds of endpoints

Any number of endpoints can listen for advertising.
1. Briefly sample the channel for any activity.
2. Check for signs that it’s a background frame (part of design).
3. Receive the background frame.
All endpoints can receive request, all can send responses, all are now synced to each
other.

4. Haystack Advanced Error Correction
• High-performance forward error correction
• Heavily utilized in cellular (3G, 4G) and other wide
area wireless networks including NASA space
probes
• Leverages LDPC and other techniques
• Relatively low complexity algorithms allow for low
power encoding and decoding
• Haystack Guaranteed Messaging allows for
intelligent re-transmit of messaging. Transmit
continues until a) packet is corrected, b) time-out is
reached, or c) Shannon limit reached.
23. Key Takeaways Re: Power, Range
Haystack offers superior range to LoRaWAN due to:
• LDPC error correction
• Fewer collisions, especially in dense endpoint environments
• Fewer dropped packets
• Dynamically configurable data rates, message sizes, other attributes
Haystack offers superior battery life to LoRaWAN due to:
• Listen-before-talk endpoints
• Fully bi-directional comms including message acknowledgement
• Dynamically configurable endpoint power profile
• Multicast-based A-GPS for outdoor location use cases
• Query-based geolocation vs. beacon-based geolocation
• “Downlink” based RSSI- and TDOA-based geolocation/trilateration
• Geofencing capability using advertising packets to trigger endpoint response

Today, no LPWAN or NB-IoT technology offers a high-precision, real
time, indoor location capability on its own.
But Haystack does this.
Endpoint
Using RSSI & RF “fingerprinting” with scattered
reference nodes: ±1m location precision has been
observed

AP
Alternatively, “nearest neighbor” location provides the RSSI value of the closest
fixed reference tag to the mobile endpoint, minimizing systems integration and
setup costs when room-level (or better) location precision is acceptable.
