Estimation and Influence of Decision Time Intervals on Wrong Decision Probabilities of Multi Handover Criteria

Abstract

In this work, simulation results are presented for handover probabilities due to wrong decisions made on a five node network. The wrong decision can be a false positive or a false negative. False positives are unnecessary handovers and false negatives are missing handovers. The probabilities of unnecessary handover, missing handover and total of unnecessary and missing handovers are computed for different decision time durations from 1ms to 5ms. Various parameters like bandwidth, received signal strength, bit error rate and mobility of mobile devices are considered as handover criteria. The parameters are added one after the other starting with available bandwidth to demonstrate the effect of various parameters on the wrong decision probabilities. The effect of duration of decision time on the wrong decision probabilities is also demonstrated for all the parameter combinations used in this simulation.
