....task must be guaranteed a priori to meet its timing constraint. Therefore, efficient scheduling algorithms and schedulability analysis are needed. Many real time scheduling algorithms, in which schedulability is a main objective function to be maximized, can be found in the literature [1] 2] 4] 5][7]. These real time scheduling algorithms fall into two categories: static and dynamic scheduling. Most of these real time scheduling algorithms have an assumption that no error occurs in real time systems. In order to make real time scheduling algorithm more practical, task precedence constraints ....

....of magnitude improvement at the application level. One way to achieve this improvement is through globally distributed databases. Such databases could be enterprise specific and offer features along real time, fault tolerance, quality of service (QoS) for audio and video and security dimensions [3]. Support of these features and potential tradeoffs between them could provide a significant improvement in performance and functionality over current distributed database and object management systems. There are many research problems that must be solved to support global, real time databases ....

....to access, the corresponding sensor transaction is blocked. Although a higher priority may be assigned to sensor transactions such that the lower priority user transaction is restarted, information may be leaked out through the covert channels when the requirements of non interference are not met [11]. Another source of latency is the general workload of the system that can sometimes delay sensor transactions from execution. Based on the time signatures of sensor transactions in real time database systems, we can build an IDS with different tolerance levels by including the dynamic behavior ....

....the Integrated Scheduler. The Java GUI in addition to the Transaction Requirements interface shown in Figure 7, will also have interfaces for a Workload Generator and also to display Monitor statistics. Simultaneously, research is also being carried out on the security issues pertinent to BeeHive [3]. Phase Two: This will involve implementing increased support for real time audio and video to and from the database. Work will also be carried out on implementing time cognizant concurrency control protocols for the BeeHive Storage Manager. After experiments with concurrency control protocols ....
