Abstract: One of the major challenges for beyond third generation mobile systems is efficient mobility management. This paper proposes a distributed dynamic management scheme of handoff based on B3G networks. This scheme can reduce the cost of update signalling and transmitting packets, and improve the system capability. In this scheme, the dynamic building network approach is adopted to deduce the update signalling cost. We implement the distributed dynamic management scheme of handoff in a simulation platform and compare its performance with that of general centralized handoff management schemes. Our simulation results indicate that our scheme is capable of reducing the update handoff latency, and enhancing the performance. 11 Refs. In English.
