Robust Prediction for Intra and Inter Handoff ( RPIIH ) Process over CDMA 2000

the overall performance of mobile nodes is mainly affected by the relatively considerable time spent in the handoff process. Most of the time spent is mainly consumed during the authentication process. This process could be even longer especially when the Access Points (AP’s) are busy, which results in delays and/or packets loss. Many handoff techniques have been proposed to shorten the time of authentication however todate, they have not been fully successful. This paper introduces a more robust technique for saving the time consumed during authentication. The adopted approach is suitable within the regions that use the intra-handoff technique as well as those applying the inter-handoff technique. To validate our model, we have used ns-2 based simulations and plotted the findings. Keywords—intra-handoff, inter-handoff, Mobility, CDMA2000, Home Network, Foreign Network, Mobile devices
