Recent growing widespread attention given to mobile communications has led to rapid growth in research and development involving mobile wireless networks. The need for easy deployment and self-configured networks makes mobile ad-hoc networks (MANETs) an attractive choice for various applications. However, due to its dynamic nature and imprecise network state information, there are many challenges which need to be addressed including Quality of Service (QoS) routing. Numerous approaches have been proposed including QAODV. It is proposed to enhance one of the existing routing protocols for MANETs namely AODV (Ad-Hoc On- Demand Distance Vector). Q-AODV adds necessary new fields to cater QoS provisioning requirements. This paper aims to conduct evaluation study on AODV and QAODV approaches. Some new fields are added with AODV to form QAODV to avoid resource wastage as well as maximize utilization of network capacity. In order to identify the pros and cons of both methods, NS-2 Simulator is used to conduct the simulation study. Throughput, End-to-end delay, Packet Delivery Ratio (PDR) and Normalized Overhead are the selected evaluation metrics. Our experiments study the effect of number of mobile nodes, mobility and traffic load.- State of the Art of Cloud Computing and its Research Issues

Cloud computing is a technology that uses the central remote servers and internet to access or maintain data and applications. It allows service consumers and businesses vendors to use applications without any software installation and access their personal files at any time and by any computer with the help of internet access facility. This technology allows more efficient computing by centralizing memory, processing, storage and bandwidth. Cloud computing technology confronted a new computing epitome in the field of internet with operable resources used as services. This forms a new horizon for business venture and projects by cutting down the entry barriers to a greater extent. The objective of this research contribution is to make spotlights on Strengths, Weakness, Opportunities and Threats (SWAT) analysis and research issues of cloud computing.Keywords

With emerging IPv6 based Standards such as ISA-100a and 6LowPAN/IEEE 802.15.4, IPv6 based sensor networks are the next era. As wireless sensor networks grow, we need implementation of IPv6 on it due to some advanced features available with IPv6 such as security mechanism. There are various challenges when implementing IPv6 on wireless sensor networks major one is interoperability with millions of deployed embedded IPv6 based devices for In-door and Out-door applications, both within the sensor networks itself and between the sensor modules and the Internet hosts. Through this contribution our objective is to explore the key features needed at network layer in WSN's protocol stack, security features of IPv6 should incorporated with next generation of WSNs, challenges faced with implementation or deployment of IPv6 on WSNs, presenting an overview of uIPv6 and recommending portability for all sensor node's operating systems and also highlighting the issues that affects security of WSNs.Keywords
