the size of sliding window affects both the self-healing capability and the communication overhead.With probability knowledge
the mathematical model is built
which reflects the influence of the size of sliding-window and packet loss rate on the performance of key synchronization
group security association and security service.Then
an adjustment mechanism of sliding window is proposed to adapt to the dynamic change of broadcast links
and a look-up table is utilized to reduce the computation and storage overhead.Simulation results show that the scheme proposed is dynamically adaptive
and guarantees the performance of security service with high probability.Compared with the existing schemes
the proposed scheme greatly reduces the communication overhead
and is more feasible and efficient.Meanwhile
it further promotes the application of self-healing key distribution.
