Abstract

Handoff in IEEE 802.11 requires the repeated authentication and key exchange procedures, which will make the provision of seamless services in wireless LAN more difficult. To reduce the overhead, the proactive caching schemes have been proposed. However, they require too many control packets delivering the security context information to neighbor access points. Our contribution is made in two-fold: one is a significant decrease in the number of control packets for proactive caching and the other is a superior cache replacement algorithm.
