The Combination of Multiple Care-Of Addresses Registration and Reverse Routing Header in Nested Network Mobility

In order to apply the Multiple Care-of Addresses Registration to the RRH scheme in nested NEMO, several problems must be resolved: the deficiency of BID to indicate all the path information, the ignorance of upper layer MR´s disconnection, and the absence of method to bind a flow to a single path. The Path ID mechanism is proposed and a solution for the above mentioned 3 problems is designed based on the Path ID mechanism.
