LoRa is a Low-power, wide-area network that allows to build systems to obtain data on long distances using low bandwith, providing a long battery life to the nodes. This tecnology has the ability to send short packets using Direct Sequence Spread Spectrum (DSSS) in large time intervals.
This project aims to implement IPv6 for LoRa networks including Neighbor Discovery service and basic IPv6 configuration.
By using SCHC, this implementation will build a table inside the LoRa gateway to map the source IPv6 header to an internal ID which will be used to identify the flow to the end-device. Any redundant information will be elided for SCHC compression and will be write back in the SCHC decompression.
In order to achieve our goal, we plan to use:
- 1 Modtronix inAir9 LoRa Modules
- 1 IC880A module
- 1 Raspberry Pi 2
- 1 Arduino unoFor the initial version of the project, the following software components are planned to be used:
end-device project - Arduino-LMIC library by matthijskooijman
https://github.com/matthijskooijman/arduino-lmic
LoraGateway project - LoRa Gateway project by semtech
https://github.com/Lora-net/lora_gatewayThis directory contains the source to use IPv6 in the LoRa devices. they can be found at the following addresses:
- LoRaGateway/libstack_ipv6/
- end-device/src/lmic/libstack_ipv6/This library comes with the implementation of SCHC and basics IPv6 functions explained in detail in its folder.
For the good operation of IPv6, the following programs were created:
Folder: LoRaGateway/project_ipv6
The goal of this program is make the Raspberry Py + IC880A works like a gateway. To make it work, you must use the following command:
sudo ./project_ipv6You can start sending and reciving package after the program says that the concentrator is ready to go.
Folder: end-device/examples/ping
The goal of this program is make the Arduino UNO + inAir9 works like a LoRa node. To start running the node, you have to upload the file in the Arduino UNO with its corresponding libraries (ends-device library).
In this project, the LoRa node was configured with the IP fe80::3.
20/04/2017 : 6LoWPAN deleted, full implementation of schc for ICMPv6 (echo request, echo reply, router solicitation, router advertisement, neighbor solicitation, neighbor advertisement, redirect ) for a star topology, the discovered devices are stored in a linked list.
15/03/2017 : Beginning multicast Development, Readmes Updates.
27/02/2017 : 6LoWPAN_IPHC and SCHC implementation for ICMP6 communication between LoRa Gateway and LoRa Node.
09/11/2016 : RoHC base and AES decryption added in LoRa GateWay. The hop limit is not configured.
