Design and implementation of a layer-II fast handoff protocol in emergency communication system
Immobility,limited bandwidth and poor support to real-time service are common shortcomings in traditional emergency communication system.Moreover,the data transmission speed is highly limited in high-speed services by the long handoff delay and fixed handoff trigger threshold when the mobile termina...

| description | Immobility,limited bandwidth and poor support to real-time service are common shortcomings in traditional emergency communication system.Moreover,the data transmission speed is highly limited in high-speed services by the long handoff delay and fixed handoff trigger threshold when the mobile terminals moving between network nodes.In order to overcome these shortcomings,a new emergency communication system with multifrequency hierarchical clustering structure was designed.A new layer-II fast handoff protocol was designed for such network structure to deal with handoff issue in real-time services.In this handoff protocol,the handoff trigger threshold is self-adaption based on the moving velocity of mobile terminals. |
