All of above is for a complete, scientific handover process.Next, the article analyzed the factors which influenced several main performance indexes like polo shirts success rate, put forward methods like using reserved bandwidth and choose BS which has light load as the target BS to improve the success rate; using none collision ranging and pre-register method to reduce the handover delay; let serve BS transmit data packet to target BS in order to eliminate the chi flat iron packet loss in the process of handover.After that, this article constructed a system simulation model by chi hair straighteners according to frame format and handover method presented before. On the basis of this model, realized the process of a MS handover between different BS, compared the different hair straighteners performance of handover decision algorithms, that is, RSS, RSSH, RSST, RSSHT, and come to the conclusion that RSSHT has the best performance. Then compared the success rate, handover delay, packet loss in the cheap ralph lauren polo shirts downlink before and after optimization. According to the analysis of the result, we can see the method this article presented can reduce the handover failure rate and the handover delay, and eliminate the packet loss in the downlink, so the performance of the system can be improved.
