Abstract
To fulfill the need for on-the-move and uninterrupted internet connectivity in Mobile Networks, IETF NEMO working group was created to extend basic end-host mobility support in Mobile IPv6 (MIPv6) protocol. NEMO Basic Support Protocol (NEMO) has been standardized by this group to provide the network mobility support. However, the handover latency in NEMO is high and, the nested tunnels’ problem in the nested NEMO networks is not considered. Many schemes have been proposed to solve these problems by optimizing the handover signaling procedure, and by proposing routing optimization scheme for NEMO. Better optimized signaling procedure is proposed in this paper, and a proposed Routing Optimization scheme as a solution for the lack of the nested tunnels’ problem is proposed as well. Analytical results highlight the importance of the proposed scheme comparing to others are provided, revealing that the proposed scheme has the lowest handover latency and disruption time.
