Network debugging has always been a challenging task primarily because the original design of the Internet architecture gave little importance to debugging and management. In addition, the Internet makes forwarding decisions in a distributed manner, which is hard to track. With the advent of Software Defined Networks (SDNs), network debugging has potentially become easier because solely the control...
In the present era of plurality and diversity in electronic world taking decision for choosing the best one from a pool of products is a prudent approach. Machine learning helps us a lot in deciding the optimal choice. Artificial Neural Network are a family of statistical learning algorithms inspired by biological neural networks and can be incorporated to take a decision at par with a smart human...
Row based relational database management systems (R-RDBMS) are the most common choice for data warehouse implementations. Row based storage is useful in online transaction processing (OLTP) to insert and update data while column oriented RDBMS (C-RDBMS) in online analytical processing (OLAP) to access data from data warehouse. This paper analyses the best suited mode of storage (row or column based...
In a post disaster situation, movement of rescue teams should be modelled effectively to ensure proper communication and co-ordination amongst different teams. For this it is necessary that movement is modelled effectively. In this paper we propose an emergency scenario movement modelling by managing the co-ordination task by a four way directional movement. The communication between the stages is...
Aggregation is a key technique to enhance query response time in a large data warehouse. This paper analyzes its effects on query performance and memory requirements. A grocery shop data warehouse has been designed for simulation purpose using Red Gate Data Generator tool along with the Business Intelligence Development Studio of Microsoft SQL Server 2008. For a desired performance gain, the requirements...
Mobile Ad-hoc Network (MANET) is a readily deployable wireless network suitable as a communication backbone during emergency response operations. These networks are infrastructure less. The goal of this paper is to simulate the scenarios for emergency situations. Various routing protocols have been proposed for MANETs like AODV, DSDV, LAR, DYMO, TORA etc. They are classified as proactive (table driven),...
Mobile Ad-hoc Network (MANET) is infrastructure less networks which can be rapidly deployed. This property makes MANET suitable in disaster management and such emergency situations. To analyse such scenarios, the node movements have been modelled variously as random waypoint, random walk, Manhattan grid model etc. Reference Point Group Mobility (RPGM) model is used in situations where nodes move in...
A mobile ad hoc network (MANET) is an infrastructure less and self-configuring network of mobile devices which dynamically form a network without the help of any centralized administration. Frequently changing network topology needs efficient dynamic routing protocols. The performance of any routing protocol depends on the duration of interconnection among the nodes in the network for transferring...
Fault Diagnostics is one of the major requirements for assuring dependability of complex systems. In Systems level diagnostic procedures applied to computer interconnection networks, the processors diagnose each other and under certain conditions faulty processors can be identified. This paper simulates a system-level diagnosis algorithm for mesh with wraparound, topology to locate the faulty units...
A meaningful definition of an "adequate" model, insofar as its function in control system design is concerned, is given. An empirical method of evaluating the adequacy of a model is developed. Based on heuristic reasoning, five parameters of the process dynamics are chosen as the critical parameters. A non-redundant number of these parameters is used both to evaluate the adequacy of a given...
