唐賓徽 陳睿 周振興

摘? 要： 由于移動通信網和無線傳感網各有特點，且各自的網絡結構和協議棧差別較大，兩網異構融合產生的多業務數據流量將同時具備局部性、周期性、隨機性、突發性等多重特點，結構復雜，對網絡運營能力及安全監測帶來了技術難題。文中針對多業務流的場景，分析各類業務流模型的特點，提出一種基于異構網的融合業務流模型，并對業務流量通過預測算法進行預測。仿真結果表明，該模型算法的預測精度較高，為異構網的多業務融合起到了重要的支撐作用。

Abstract： Since both the mobile communication networks and the wireless sensor networks have their own characteristics， and their network structures and protocol stacks are quite different， the multi?service data flow generated by the heterogeneous integration of the two networks are of the characteristics of locality， periodicity， randomness and burst property， as well as complex structure， which brings technical problems to network operation capability and security monitoring. In view of the above mentioned， the characteristics of various service flow models are analyzed on the basis of multi?service flow scenarios， and an integrated service flow model based on heterogeneous network is proposed， and the service flow is predicted by the prediction algorithm. The simulation results show that the prediction accuracy of the model algorithm is high， which plays an important supporting role for multi?service integration of heterogeneous networks.

Keywords： heterogeneous network; converged service flow model; prediction algorithm; wireless sensor network; mobile communication network; model analysis
