A massive segment of information terabytes is produced daily due to the advent of technological systems and modern systems such as cloud computing and the Internet of Things (IoT). The evaluation of the big data analytics impacts significant effort of the many dimensions considered in the process of extracting data that is essential for the process of making proper decisions in an organization. In that regard, big data analytics is the immediate area of concern for research and development experts. The primary purpose of this paper is to provide an analysis of the big data analytics, including the issues and tools linked to the process of extensive information analysis. Moreover, this academic paper presents an avenue that stimulates the exploration of big data at an incredible measure. As such, this research provides a new platform of analytics to formulate a remedy to the problems and the gaps available in research.

Packet arrival-delay variations and losses seriously affect the quality of voice delivered in VoIP. In this paper, using a time-scale modification algorithm, an integrated scheme is proposed to handle these impairments without introduc ing additional delays. This scheme provides flexible arrival delay cut-offs to late arriving packets, reducing the packet loss-rate at the receiver. Further, the lost packets are con cealed effectively. Extensive simulations have shown that the proposed scheme delivers high-quality speech across widely varying packet arrival-delays and loss-rates. The proposed scheme is fully receiver-based and with its low computational complexity and generic nature, is applicable to any VoIP system.

Multihop Wireless Broadcast is an important factor in VANET. Broadcasting is the most common operation which is used by many applications. But efficiency in routing is difficult to achieve. Many other protocols consider the performance degradation based on the factors like Node density, spatial distribution pattern and channel quality. Distribution Adaptive Distance with Channel Quality (DADCQ) protocol overcomes these factors considering all the three factors. The protocol utilizes the distance method to select forwarding nodes and also the results to achieve high reachability and low bandwidth consumption in urban and highway scenarios. But there is no guaranteed packet transmission and selecting threshold value by considering all the difficult factors. This can be achieved by using Position Based Routing Protocol by put into action of GPRS Algorithm. The PBR protocol makes use of location information and suited for distributed, centralized and decentralized systems. Thus the proposed system will considerably reduce packet loss and to improve throughput.
