Abstract

This paper presents a method of Token Validation of a wireless recharge token in Prepayment Energy meter
without recourse to any server. Most proposal on wireless recharging have suggested token validation at the server in the
Supply Authority’s office. The need for Prepayment Energy Meter to be able to validate token from a wireless source without
the help of an intermediary system is highly desirable. The Prepayment Meter is realized with an ADE7755, Atmega328 and
Atmega2560 in its circuitry among other components. The ADE7755 gives the load pulses that are measured and recorded by
Atmega328P. Atmega2560 manages the units according to consumption. It also controls and monitors the activities of the
meter and receives token for recharge from a GSM Short Message Service (SMS) platform using SIM900 as the gateway. It
also comprise of a Liquid Crystal Display (LCD) for displaying unit balance and other information. The microcontrollers are
programmed in C++ language with a Data Encryption Standard (DES) built in a Labview environment used in the token
validation algorithm incorporated in Atmega2560. The results obtained show a mean signaling time for SMS recharging of
20.50s and 100% success rate in wireless recharging showing correct validation of recharge token by the meter. With the
results obtained, token recharge from wireless sources, especially the SMS can be validated without recourse to a server
anywhere.
