Explicit Routing Designation (ERD) method the cache information in nested mobile networks

초록

HMIPv6 supports the transmission delay between mobile node and correspondent node, handoff signaling and data transmission as introducing an local Home Agent(HA) of new type called MAP(Mobility Anchor Point). Mobile network may generate not only the nested mobile network structure but also a single network because of the node mobility or router mobility. Many subnet exist and several mobile routers or mobile nodes operate in the nested mobile network. This paper proposes the ERD method that a packet entering from MAP to MAP domain decides the explicit routing for correspondent destination node through changing the binding cache structure of MAP domain. We can decrease in quantity of unnecessary packets if we transmit a packet in MAP using ERD method and also reduce an transmission delay because an intermediate mobile router can re-transmit a packet using just the simple packet substitution. © Springer-Verlag Berlin Heidelberg 2007.
