For the transfer of messages in a DTN, various routing schemes have been proposed but there has not been an umpteen amount of work related to their comparisons. Therefore, a study of the routing techniques, issues in DTN connectivity and performance analysis of routing algorithms in DTN have been showcased in the current work. This analysis would help the researchers in identifying the most efficient routing scheme amongst well known routing algorithms.","PeriodicalId":374882,"journal":{"name":"Int. J. Auton.

Translating high-level business policies into low-level tuning actions and parameters is, however, a non-trivial problem as there is little similarity in the metrics used for measuring database performance and business performance. These translations can be simplified, however, by having a model that reflects the business policies. In this paper, we utilise an economic model to implement importance policy as a parameter for the allocation of system resources. The relative importance of the workloads can therefore be utilised in allocating system resources, such as main memory for buffer space and shares of the CPU. We simulate the model in order to demonstrate the effectiveness of the approach. We present experiments to show the impact of the relative importance of workloads on the allocation of resources, specifically buffer area and CPU.","PeriodicalId":374882,"journal":{"name":"Int. J.

The data collected for stock market is in the form of breaking news from various finance websites. The TF-IDF features extracted from online news data are used for creation of HMM model along with log likelihood values. The next day's stock price is predicted as either higher or lower than current day's stock price. Results obtained from proposed model is compared with results from other machine learning predictive techniques such as random forest, KNN, multiple regression, bagging and boosting. The proposed model produces approximately 70% of accurate prediction. The captured features are graphically represented with word cloud.

The major strategies in wireless network were security and trustworthiness. Due to the denial of the service attacks, most of the communication was disrupted. That was overcome by a new proposed algorithm called reverse tracing algorithm, which helps to find the attackers through reverse tracing messages. If the acknowledgment is received after every successful transmission, that was considered a secure communication. If it did not receive the acknowledgement properly, that will be considered as an unsuccessful transmission. By using this reverse tracing algorithm, we can identify the attacks. Simulation were performed using network simulator tool and then parameters such as throughput, delay, drop rate, goodput and packet delivery ratio was analysed. Compared to the previous approaches, the proposed reverse tracing algorithm achieves good performance.","PeriodicalId":374882,"journal":{"name":"Int. J. Auton.

The proposed method is based on lower order models obtained from slow or fast dynamical systems. In the proposed method, the sliding mode controllers (SMCr) are designed based on the three term controller (PID) with first order filter sliding surface. The motivation for the proposed work in this paper is that the methodology adopted for controller design is applicable to general unknown class of SISO systems. This systems having lower or higher order dynamics, oscillatory or monotonic behavior and with or without time delay. The performance of designed controller is excellent for variation in parametric and unmodeled uncertainty in the system. The robust property of the proposed method is verified by applying an external load disturbances (fixed and variable). The stability and robustness of the proposed controller are investigated using Lyapunov stability theorem. The high frequency chattering phenomenon which commonly occurs in SMC controller, is significantly reduced by adopting the switching gain with the known parameters of the system. The performance of the proposed SM control method is validated with the help of simulation examples and results are compared with other control methods available in the literature.","PeriodicalId":374882,"journal":{"name":"Int.
