Fast and Route Optimized NEMO (FRONEMO): A proposal to improve handoff performance in network mobility

摘要

To reduce handoff latency (resulting in packet losses) and packet transfer delay (due to triangular routing) in NEMO Basic Support Protocol (NBSP), we propose Fast and Route Optimized NEMO (FRONEMO), which brings in the concept of IP pre-fetching and advance-registration to acquire care-of-address for the anticipated future cells. Also, FRONEMO uses the prefix delegation technique in route optimization with minimal control packet overhead. Analytical comparisons between FRONEMO and NBSP reveal that FRONEMO can support higher vehicle speed and still has significantly low handoff latency, lower packet loss, and higher throughput.
