Abstract :
This paper presents a Spectrum Reuse/Token Passing (SRTP) protocol for communications over power lines for monitoring and control in a factory environment. The paper presents a new method for organising a sensorial token passing network in multiple logical rings using a centralised scheduler. It also presents a technique for increasing the power grid bandwidth by splitting up the power grid, using power EMI filters. The SRTP protocol is analysed in terms of token cycle time and its performance is compared to the token bus passing protocol
