Abstract
Re-establishment of the QoS after a Mobile Node handover must be done as quickly as possible in order to reduce degradation or interruption of QoS, especially when realtime applications are used. We propose a Semi-Proactive procedure for a faster QoS re-establishment in environments where there are Mobile Nodes. The basic functionality of this procedure is to perform as many operation as possible before the handover (in a proactive manner). Resources are reserved after the handover on the effective new data path in order to avoid their waste. Moreover, we propose to buffer at the Candidate CRossover Node - CCRN (an intermediate node on end-to-end data path) the packets directed to the Mobile Node during the handover. In this way the total QoS re-establishment time is reduced. This buffering also guarantees the same QoS treatment of both the buffered and the non-buffered packets.
