Abstract:In order to resolve the scalability and handover performance issues of existing approaches, we propose a scalable mobility platform which is based on the hierarchical Distributed Hash Table (HDHT), referred to here as MoHiD, to provide host mobility through a hierarchical DHT. In MoHiD, the location information of the hosts is stored in the HDHT running on the MoHiD Access Router to provide mobility. In the HDHT, the storage level of each entry can be specified, which drastically reduces the handover delay by limiting the number of overlay hops occurring during the query processing steps. In order to demonstrate the feasibility of MoHiD, we used a commercial cloud to measure the entry query time of the HDHT on the global scale and constructed a testbed to measure the handover performance. The experimental results show that the HDHT query delay and the total handover delay are 16.7 ms and 115.9 ms, respectively, this providing evidence of rapid handovers.
