In mobile ad hoc networks, Quality of Service (QoS) routing is a challenging issue due to several factors like node mobility, multi-path communication and channel access. QoS guarantees are required by most multimedia and other real-time applications. The difficulties of the QoS routing have limited the value of MANETs. Many researches have been done so as to provide QoS assurances in MANET routing protocols. In recent years a number of QoS routing protocols with distinguishing features have been proposed. This paper presents a survey of some of these protocols which include a thorough overview of QoS routing metrics, resources and factors affecting the performance. The protocols are classified according to the multi-path, cross layer, stability, bandwidth reservation, load balancing and power efficiency based approaches. The relative strengths and weaknesses of the protocols have also been studied which allow us to identify the areas for future research. Finally, a comparative study of all routing protocols is provided. Copyright © 2012 Inderscience Enterprises Ltd.

A Mobile Ad hoc Network (MANET) is an autonomous collection of mobile nodes forming a dynamic network and communicating over wireless links. Owing to its uniqueness such as easy deployment and self-organizing ability, it has shown great potential in many civil and military applications. As MANETs are gaining popularity, their need to support real time and multimedia applications is rising as well. Such applications have Quality of Service (QoS) requirements like bandwidth, end-to-end delay, jitter and energy. Consequently, it becomes very necessary for MANETs to have an efficient routing and QoS mechanism to support these applications. A number of QoS routing protocols with distinguishing features have been proposed recently. This paper presents a thorough overview of some of the QoS routing protocols along with their strengths and weaknesses. A comparative study of the QoS routing protocols is done and in addition, the current issues and future challenges that are involved in this exciting area of research are also included. © 2013 IEEE.

These days, Biometric technologies are used to analyze human characteristics for security purposes. The most common physical biometric patterns analyzed for security purposes are the fingerprint, hand, eye, face and voice. The advantages of using biometrics to verify a person's identity over using passwords or token have been broadly presented in many research papers. However recent research has revealed that biometric technologies can be defeated with low -tech and cheap materials. This provides a new challenge when people are encouraged to use biometrics as a means to enhance network security. In this paper many approaches have been discussed to counteract security threats. We have also proposed a new method called Biometric Encryption which uses fingerprint and cryptography for enhanced security © 2011 Springer-Verlag.

The software industry is at its peak all over the world. Different software follows diverse development models. Based on the development model, any software can be divided into two categories namely proprietary and OSS. The OSS development is now very crucial for economic growth of any country. An estimated 2 billion dollars can be saved in India alone by adapting to open source software development methodology [26]. OSS development has some challenges associated with it. This study aims for improvements in the security and quality concerns of these systems. In this paper we have qualitatively addressed major challenges in OSS development and hence a new model for quality assurance of open source software is proposed. © 2012 IEEE.

Due to the mobility and limited energy of the mobile nodes, frequent link failures occur in mobile ad hoc network (MANET) which makes quality of service (QoS) routing a challenging task. In this paper, we consider these issues and propose a cross layer weight based on demand routing protocol (CLWORP) which uses the weight-based route strategy to select a stable and energy efficient route in order to enhance quality of service performance. The weight of a route is decided by three factors: link signal strength, residual energy and drain rate. Multiple routes are discovered from the source node to the destination node with the different weight values. Then the path with the largest weight value is selected at the destination. Simulation results show that the proposed CLWORP outperforms AODV especially in a high mobility environment. © Copyright 2016 Inderscience Enterprises Ltd.
