ToLHnet: A low-complexity protocol for mixed wired and wireless low-rate control networks
Giorgio Biagetti, Paolo Crippa, Alessandro Curzi, Simone Orcioni, Claudio Turchetti · 2014
ToLHnet (which stands for “tree or linear hopping network”) is a powerful yet simple networking protocol we developed in order to support the creation of mixed networks, employing wired and wireless connections over different media among thousands of nodes. It is based on tree routing, with special care to support the degenerate case of linear routing, to keep implementation on nodes simple and protocol overhead low. This paper describes the essentials of the protocol and presents a case study detailing its implementation and performance on a Texas Instruments TM4C123GH6PMI microcontroller, with the addition of a power-line-communication modem and a 433 MHz radio.
