Abstract
Developing an imitation model for radio channel to deliver data from meters to GSM-concentrator in the innovation system of complex account, recording and analyzing energy and water consumption by industrial enterprises and objects of housing and communal
Incoming article date: 25.11.2016This article describes an estimation of developed data exchange protocol robustness. Protocol is used in wireless connectivity. This protocol was made for delivering data from a meter to GSM-concentrator. This system is a part of hardware-software complex for energy resources and water metering. To solve this problem an imitation model was developed, which consider various collisions on the line. The purpose of modeling is to estimate probability of failure while transmitting daily data from meters to GSM-concentrator. The model was made of N random number generators, the period of time is divided into time slots. These generators give random slots which is a modeling of random transmissions. During modeling we consider a simultaneous transmission of two generators as a failure. Then the model was modified to address the possible “semi-collision”, when two generators use slots which are close to each other. The results of modified model show that probability of failure using developed protocol is negligible.
