Description

The mobile data traffic has been extremely expanded for years and will remains the high growth rate in a long term. It is believed that distributed mobility management has been developed to be a new trend of designing mobility management scheme to solve the problem caused by the increasing traffic volume. In Distributed mobility management frequent unwanted Location updating between mobile nodes and mobility agents cause signal overhead. To reduce the signaling overhead, the system proposes a timer-based Bloom filter aggregation (TBFA) scheme for distributing the location information. To reduce the signaling overhead, the system proposes a timer-based Bloom filter aggregation (TBFA) scheme for distributing the location information. In the TBFA scheme, the location information of MNs is maintained by Bloom filters at each MA. The Whole Bloom filter for every MN movement leads to high signaling overhead, each MA only propagates changed indexes in the Bloom filter when a pre-defined timer expires.
