Scalability of Time Synchronized wireless sensor networking

Abstract

Existing commercial wireless sensor network solutions use Time-Synchronized Channel Hopping (TSCH) to achieve an end-to-end reliability higher than 99.9% and industry-accepted network lifetime (5–10 years on batteries). In these types of networks, once nodes synchronize, they follow a schedule which determines the time and frequency of the channel that is used to transmit and receive. Standards such as WirelessHART apply this technique. This paper addresses the ability to scale such a scheduling approach for specific applications.
