Named Entity Recognition System for Sindhi Language

Named Entity Recognition (NER) System aims to extract the existing information into the following categories such as: Persons Name, Organization, Location, Date and Time, Term, Designation and Short forms. Now, it is considered to be important aspect for many natural languages processing (NLP) tasks such as: information retrieval system, machine translation system, information extraction system and question answering. Even at a surface level, the understanding of the named entities involved in a document gives richer analytical framework and cross referencing. It has been used for different Arabic Script-Based languages like, Arabic, Persian and Urdu but, Sindhi could not come into being yet. This paper explains the problem of NER in the framework of Sindhi Language and provides relevant solution. The system is developed to tag ten different Named Entities. We have used Ruled based approach for NER system of Sindhi Language. For the training and testing, 936 words were used and calculated performance accuracy of 98.71%.

A Framework for Debugging Java Programs in a Bytecode

In the domain of Software Engineering, program analysis and understanding has been considered to be a very challenging task since decade, as it demands dedicated time and efforts. The analysis of source code may occasionally be comparatively easier due to its static nature, however, the back end code (Bytecode), especially in terms of Java programming, is complicated to be analysed. In this paper, we present a methodological approach towards understanding the Bytecode of Java programs. We put forward a framework for the debugging process of Java Bytecode. Furthermore, we discuss the debugging process of Bytecode understanding from simple to multiple statements with regards to data flow analysis. Finally, we present a comparative analysis of Bytecode along with the simulation of the proposed framework for the debugging process

Cloud Service ranking using Checkpoint based Load balancing in real time scheduling of Cloud Computing

Cloud computing has been gaining popularity in the recent years. Several studies are being proceeded to build cloud applications with exquisite quality based on users demands. In achieving the same, one of the applied criteria is checkpoint based load balancing in real time scheduling through which suitable cloud service is chosen from a group of cloud services candidates. Valuable information can be collected to rank the services within this checkpoint based load balancing. In order to attain ranking, different services are needed to be invoked in the cloud, which is time consuming and wastage of services invocation. To avoid the same, this chapter proposes an algorithm for predicting the ranks of different cloud services by using the values from previously offered services.

Secured Approach Towards Reactive Routing Protocols Using Triple Factor in Mobile Adhoc Networks

Routing protocols are used to transmit the packets from the source to the destination node in mobile ad hoc networks. The intruders seek chance to pierce into the network and becomes a cause of malfunctioning in the network. These protocols are always prone to attacks. During the phases of routing in different types of protocols, each of the attack finds a way to degrade the performance of the routing protocols. The reactive routing protocols DSR and AODV have lot of similar features and so are considered in this study. In order to transmit the packets safely, a secured approach using triple factor has been proposed. This triple factor computes the trust by using the direct information then verifies the reputation by collecting the information from the neighbouring nodes called distributed factor and uses cryptographic algorithm to ensure security. And to ensure that there are routes available to perform the routing process, the reasons for such attacks are studied so as to re-integrate back the nodes in to the network, once it has repented for being malicious before. The availability of routes increases the throughput

Improving Privacy and Trust in Federated Identity Using SAML with Hash Based Encryption Algorithm

Cloud computing is an upcoming technology that has been designed for commercial needs. One of the major issues in cloud computing is the difficulty to manage federated identities and the trust between the user and the service providers. This paper focuses on how security can be provided between the user and the service provider and how the user information can be authenticated. For the purpose of providing privacy and authentication, Security Assertion Markup Language (SAML) based Single Sign-On is used. Security is provided by using Hash based Encryption algorithm (HBE). HBE algorithm works with the help of Key Exchange Protocol which contains poly hash function. In the algorithm, Identity providers maintain user directory and authenticates user information; service provider provides the service to users. The user has to register their details with the identity provider prior to this. During this stage, Hash based Encryption algorithm is used to provide secure communication between the identity provider and the user. In this paper we suggest that higher security can be given to user login by using an additional cryptographic technique, i.e. Hash based Encryption algorithm with the help of the Key Exchange Protocol.

Ideal Node Enquiry Search Algorithm (INESH) in MANETS

The different routing protocols in Mobile Ad hoc Networks take after various methodologies to send the data starting from one node then onto the next. The nodes in the system are non-static and they move arbitrarily and are inclined to interface disappointment which makes dependably to discover new routes to the destination. During the forwarding of packets to the destination, various intermediate nodes take part in routing, where such node should be an ideal node. An algorithm is proposed here to know the ideal node after studying the features of the reactive routing protocols. The malicious node can be eliminated from the networking function and the overhead on the protocol can be reduced. The node chooses the neighbor which can be found in less number of bounces and with less time delay and keeping up the QoS.

Treatment of Reactive Routing Protocols Using Second Chance Based On Malicious Behavior of Nodes in MANETS

Mobile nodes of various routing protocols in Mobile Ad hoc Networks follow different strategies in transmission and receiving of data. Security, packet delivery and routing overhead are important concerns for any protocol during designing them. The presence and absence of malicious nodes in the network affect a lot on the performance of the protocol. This research is mainly focused on the study of the threats, attacks and reasons for malicious behavior of nodes in the network for reactive routing protocols in MANETS. DSR and AODV are the two reactive routing protocols that were considered for the study to propose a second chance strategy to be given to the nodes considering the reason for malicious behavior to improve the packet delivery ratio and reduce the routing overhead in the network. A simulative study has been conducted using Ad hoc Simulator (ASIM) considering the DSR and AODV routing protocols in the presence of malicious nodes and in the absence of malicious nodes which showed that the packet delivery ratio is low and routing overhead is high in the absence of malicious nodes. The second chance strategy proposed considers the reasons for malicious behavior and helps the node to get reintegrated in the network to improve the packet delivery ratio and reduce the routing overhead.
