Abstract:

For supporting efficient host mobility and mapping identifiers onto locators,a distributed dynamic mobility mapping scheme based on cost function was proposed.In the scheme,depending on the mobility pattern and communication feature,the communication of mobile node is divided into three communication models,namely,moving update model,balanced transmission model and resolving query model.In order to minimize the total resolving cost,three mapping approach are proposed based on distributed multicast,consistent hash functions and proactive sharing respectively in the mobile domain.For each mapping approach,corresponding registration update,resolution query and packet delivery strategies are designed.Simulation results show that the scheme can achieve the minimum resolving cost,and can have low resolve latency and good adaptability for network topology dynamic changing.

Key words: mapping system, identifier/locator separation, mobility, distributed
