A packet-scheduling strategy for heterogeneous traffic of Internet of Things
Jun Xu, Chengcheng Guo, Wenxiang Li, Hao Jiang · 2012
In this paper, we give classification for various traffics in Internet of Things according to such features as packet length and importance, and propose priority-based scheduling strategy for efficient packet transmission. Detailed theoretical analysis based on one-server queuing theory is provided to show the superiority of short-packet-first non-preemptive strategy over other strategies. And by simulation experiments in NS2, we verify the effectiveness of our method in term of such performance metrics as end-to-end delay, packet delivery ratio and processing overhead.
