Scalable Routing for Low-Bit-Rate Wireless Mesh Networks
Mesh networks are decentralized, infrastructure-less peer-to-peer networks that can provide instantly-deployable connectivity between users. In this talk, I will consider a class of mesh networks built using low-cost, low-power, long-range devices for applications such as hurricane relief, forest fire fighting, wildlife monitoring and long-range IoT. Tradeoffs in such networks limit the transmission bit-rate, making the problem of routing messages efficiently to their destination(s) particularly challenging. After a brief overview of mesh routing, I will present a new approach based on embedding control information within data packet headers, and discuss its scalability properties. I will outline two embedded-control protocols that are implemented in the goTenna mesh devices, their performance, and some deployment use cases.
