Micro-NEMO++: An efficient micro-mobility protocol for network mobility

Designing an efficient micro-mobility scheme for network mobility (NEMO) is an important issue. The Micro-NEMO is a well known protocol for micro mobility in NEMO. It has significantly lower signaling overhead and handoff latency. But, it suffers from single point failure problem. In this paper, we propose micro-NEMO++, an extension of micro-NEMO protocol, to eliminate the single point failure problem. The micro-NEMO++ has similar cost of deployment as in micro-NEMO. The numerical results indicate that micro-NEMO++ has low signaling overhead and achieves low average handoff latency when compared with NEMO basic support protocol and micro-NEMO protocol.
