Seamless Handover Mobility Schemes over High Speed Wireless Environment

Rapid technological advance in computer and wireless mobile communication has widened the Internet functionality to be practically used in daily’s life. This advancement has offered Internet accessibility at anytime and anywhere including high speed wireless environment such as in high speed trains, fast moving cars etc. However, wireless Quality of Service (QoS) provisioning in such high speed movement is more difficult and challenging to be tackled than in a fixed-wired environment. This challenge has boost development of numerous schemes that has concerned with the needs to provide smooth handoff in such high speed mobility. This paper discussed several seamless handover protocols that can guarantees and maintain high QoS in high speed mobile nodes. The paper also focused on one selected protocol that has been identified to have the ability to perform well in high speed environment. The limitations of the selected protocol have been identified and a prediction technique is proposed to improve and optimize its performance in high speed environment.
