Abstract


With the rapid development of mobile communication network with Internet technology , the distinction between the mobile communication network and the Internet is gradually disappearing , and this will lead to a fusion of the birth of the next - generation mobile networks of the mobile communication network and the Internet . One of the biggest features of the mobile network is one of the nodes will continue to move the mobile network mobility management is very important . The mobility management of the mobile network includes location management and handover management , this article is mainly the problem of the location management study . In this paper, a single point of failure location management of mobile IP and Dynamic Domain Name System technology exists to the mobile node location management model based on the Chord protocol PLM ( Peer - to -peer Location Management) . The model location server form a fully distributed structured P2P network by Chord protocol nodes join and leave the organization . Chord protocol using SHA1 hash function to the mobile node location information is uniformly distributed in each location on the server , so the load is balanced . When the location server nodes increases , as demand increases , the ability to serve also increasing PLM model is therefore scalable , and can better resolve existing location management techniques a single point of failure problem . Find and update delayed two important indicators of the performance of mobile node location management strategy , delay the smaller , the higher the performance . The simulation results of the model show that the PLM model Find update delay smaller . In addition, research on the the PLM model of authentication , data encryption and other security mechanisms , security mechanisms can guarantee the basic inter-node mutual authentication and data confidentiality, integrity , anti - replay attack .
