Network Discovery Mechanisms for Fast-handoff

摘要: Proactive handoff mechanisms involving secure pre-authentication and proactive configuration help reduce the delay transient data loss for real-time communication during movement between homogeneous or heterogeneous access networks. Pre-authentication is meant to perform authentication with a network before mobile moves into network. To achieve pre- target neighboring network, needs obtain an IP address of server from when still outside then establish security association agent in This requires discover parameters various elements ahead time so that can communicate these associations. We describe several approaches networks moving also how discovery provide fast-handoff using acquisition handover different
