An Eco-Friendly Efficient Cloud-Searching Technique With Delay

Introduction

Cloud (Amazon Cloud Search, 2015) is a concept, based on network-based technique. Cloud disk searching technique (Cloud Computing, 2009) is mainly used to search data from memory or disk. Different types of searching techniques used in research works are linear search (Lipschutz, 2006), binary search (Lipschutz, 2006), hashing (Hashtag Definition, 2015). Delay means total time taken to search an element or item from the disk. There are two types of delay, such as cloud network delay and execution delay. Complexity is of two types, such as time complexity and space complexity. Time complexity is execution time taken to finish a program as suggested by researchers (Cormen et al., 2001).

Researchers have developed data searching techniques to find the location of a given item or data within a collection of items. There are different types of searching techniques such as linear search or sequential search (Lipschutz, 2006), hashing, and so on. Time complexity of linear search is O (n). In several papers, hashing techniques are utilized with division method (Tanenbau et al., 1983), mid-square method (Zhu, 2001), and folding method (Berenbrink et al., 2006). The utility of divide and conquered method is also a useful technique as suggested by the researchers (Falcou et al., 2006). In divide approach, problem is divided into specific sub-problems. Sub-problems are divided again into sub-sub-problems, provided that each sub-problem is represented the part of original problem. In conquer approach, sub-problems are solved individually and merge the solution of sub-problems and get the solution of original problem in this fashion. Examples of divide and conquered method are binary search, merge sort, quick sort.

Green cloud computing (Gleeson, 2009) is defined as study of designing the computing devices and manufacturing of computing devices which reduce the environmental impact. Green computing (Buyya et al., 2008) is also known as green information technology (Baliga et al., 2010). A preliminary discussion on disk searching has been published in (Sarkar & Kundu, 2015). Energy efficiency (Cavallo, 2001) helps to visualize the control of energy through a system framework. In an energy efficient system, the amount of energy required should be reduced in a controlled manner to achieve products and its corresponding services (Marti et al., 2000).
