We present improved SNR-based packet scheduling (I-SPS) algorithm as an extension of SPS algorithm. In I-SPS, the connection with better channel condition will be assigned higher weight in scheduling and the connection suffered burst error will be compensated by increasing its weight after its channel condition becomes good. Theoretical analysis and(More)
In this paper, we firstly propose self-similar traffic rate estimating algorithm PLMA for active queue management scheme to regulate packet marking probability. This algorithm improves the availability of the rate estimation algorithm under the self-similar traffic condition. Then, we design a robust AQM mechanism based on rate estimated by the PLMA, which(More)
This paper investigates the possible effect of "special nodes" in ad-hoc communication network topology on self-organized criticality. Due to increasing demand for ubiquitous connectivity without fixed infrastructures, recently, some approaches let ad-hoc communication networks having small- world property through the introduction of "special nodes".(More)
