Abstract: In this work a novel method is proposed to compute the wrong decision probability, unnecessary handover probability and missing handover probability. Three different criteria, namely, bandwidth, BER and signal strength are considered in different combinations to determine the handover probabilities. The simulations are conducted for 5 node network model. Probability equations are inferred for a general handover models. Signal strength is added to the criteria to reduce the probabilities and BER is added to capture the uncertainties better in the data transmission, while bandwidth is a network parameter. The decision times are varied to understand the effect on the handover probabilities. Results are presented for a case 16 channels in the networks. It has been demonstrated with the simulations that handover probabilities can be reduced by adding signal strength to the list of criteria while retaining all the uncertainties in the data transmission.
