Abstract—Rate monotonic (RM) scheduling algorithm cannot guarantee schedulability of highly utilized tasks in all cases. In this paper, we increase schedulability of RM by assigning fixed set of priority promotions for each task. We present an algorithm to assign promotion times (PT) and the new priority at each PT. Each priority promotion occurs after a constant relative time from the release ...

This article provides an effective method to analyze the performance measures of non-preemptive fuzzy priority queues with unequal service rates. Here arrival rate and are in numbers. Using a new ranking method, values reduced crisp values. For that cause, both Triangular Fuzzy Number (TFN) Trapezoidal (TpFN) chosen establish proposal's effectiveness. An illustration is given find efficiency qu...

The media, especially the video delivery over mobile channels may be affected by link outages and transmission bit rate variations due to the actual channel condition and the used wireless interface. In this paper we present the use of Priority-based Transmission Scheduling of SVC media data to overcome link outages and reduction in channel bit rate in mobile networks. The Priority-based Transm...

Emergency service has become an important application in telecommunications today. System resources can be shared with higher priority given to the emergency users by using a practical priority access procedure though ordinary traffic will suffer some impact. In this paper, a priority access procedure using one of three different priority access algorithms is designed based on the architecture ...

We propose a token-bucket based rate control algorithm that satisfies both maximum and minimum rate constraints with computational complexity of O(1). The proposed algorithm allocates the remaining bandwidth in a strict priority queuing manner to the flows with different priorities and in a weighted fair queuing manner to the flows within the same priority. key words: token bucket, rate control...

This paper presents a priority approach for censorious real-time traffic which flows particularly for low data rate wireless sensor and actor network (LR-WSAN). In the recent years, the demand for low rate wireless data transmission has been increased drastically in small scale industrial and non-industrial applications. The different traffic flows are increased by incorporating a variety of di...

We present an simulation experiment that can be used to asses the impact of using traffic prediction for online control on the performance of communication networks. A server with fixed output link bandwidth and impaired with high priority traffic is considered. The server shares its remaining available rate over K contending low-priority input streams queued at the input. An adaptive linear fi...
