COMMUNICATION DEMAND MODEL IN CENTRALIZED MEASUREMENT SYSTEMS

L. C. Ribeiro, R. C. S. Machado, L. F. Rust
  • Abstract:
    The present work is a study of communication demand in centralized measurement systems. The study is based on a probabilistic consumption model and an architecture where a single communication server, typically located in a data concentrator, must provide communication for several pairs meter/display. We conclude that, for typical consumers (200kWh/month) and a specific architecture (one communication interface serving 10 pairs meter/display) an event of several (more than five) simultaneous communication requests is very rare. We also describe a criteria that maximizes the number of retransmissions of each message within a maximum “time to live”; such policy is important when the communication channel is unidirectional and there is no communication confirmation.
