Abstract
Multimedia applications bring demands on broadband real-time data transfer, which needs resource reservation protocol (RSVP) helps to satisfy. However, handover processes bring delay, and existing authentication mechanism makes it further worse. Based on Pareto distribution patterns of mobile station communication traffic, proposed a trust transfer mechanism to execute pre-anticipated trust transfer and shorten the delay. It means that the dominant minority correspondent nodes designed in the VIP address books are informed about trust context messages, such as the information of handover, AAA, QoS, before anticipated handover. With the trust transfer mechanism, the simplification can be made to the authentication mechanism, which divides trust handover sequencing into several paralleled parts and budges some steps between stations. Thereby cut processes on each node by processes simultaneously carrying. Simulation with a modified NS2 platform showed that when time setforward equals 0.2, the delay is reduced by about 19.12% and the resource possession of RSVP is mitigated by 30.13%.
