Description

Open IoT mesh routing: Decentralizing long-range packet radio networks. Disaster.Radio is a project dedicated to enabling communication in real-time disaster scenarios using solar-powered, long-range, low-bandwidth radios. The project aim is to design a mesh routing algorithm suitable for Disaster.Radio and similar hardware. Objectives are a write-up of the proposed algorithm followed by implementation. The final step will be field-testing on Disaster.Radio hardware deployed around Oakland and Berkeley.

What is a Chapterthon?
Chapterthon is a global Internet Society (ISOC) Chapters marathon, where all ISOC Chapters can participate by developing a project within a timeline and budget to achieve a common goal for the development of Internet. Once the project is finalized, the best project receives a prize.

On behalf of the community networks, special interest group, our project for the Internet Society chapter thon was to design a routing protocol for low bandwidth lor networks such as the disaster radio network disaster radio is a long-range mesh network powered by the Sun. This network consists of small low-cost mesh nodes that can be mounted on rooftops or other tall structures. Each node is completely off the grid and self-contained disaster area. Nodes are capable of interconnecting over several miles.

Add as many nodes as you want, and disaster EO can provide complete coverage in any environment for our chapter thon project. You want to make this mesh network aspect of disaster radio a reality. We were familiar with Laura when but know that it relies on a client gateway configuration and does not have meshing capabilities. Yet there are very few other layer, two options for Laura networks that are both open source and well maintained. Given the limitations of Laura networks, we designed our own network stack from the physical layer of the ambitiously titled Laura layer.

2 was intentionally designed for a peer-to-peer mesh structured network. This new layer 2 allows nodes to relay messages intended for neighboring nodes, rather than a wine interact connection to a gateway or server to design and test our proposed protocol. We built a network simulator that allows us to program virtual nodes just like they were real disaster radio nodes. Each of these green dots represents a node when nodes first join a network. They enter a learning state in which I discover possible routes by broadcasting packets represented by the emojis and listening for packets from their neighbors.

Ideally, once a node has a route to every other node, it can begin forwarding packets notice how the emojis stay the same, as is retransmitted by each node in the route. The details of the protocol we developed can be found at the following link. We are hoping that this Laura layer, 2 protocol, is adopted by other projects that are harnessing Laura technology, such as grey cat and project Lantern. We are also looking to expand our collaborations Wi-Fi mesh network projects such as people's open, Libre, mesh and Toronto mesh net.

The next steps in this project are to generalize the code for laura-leigh or to so it may be tested on real devices, including our disaster. Radio hardware.
