Critical Analysis of Performance Optimization of Mobile Web Services in Cloud Environment

Abstract

In today`s world of science & technology mobile device especially Smartphones plays the role of “"Jinn" who fulfill demand of the user. Smartphone through its Internet facility allows users to access various internet based web services ubiquitously to fulfill his/her demand. Web Services can be of two types SOAP or Restful services. Many researchers have mentioned that SOAP based services are heavy to consume on mobile device despite the fact that most of the companies still uses SOAP services but answer to this challenge is Restful Web Services. Restful services also surfers from many problems like processing of work or accessing services on device due to mobile phone`s small screen size, low processing power, less memory storage capacity etc. That`s why the heavy processing work is shifted on Cloud and only client part will be on mobile device, this integration is called as Mobile Cloud Computing (MCC). In MCC important point need to consider is to improve the performance of web services in terms of speed, memory usage and reducing latency. To resolve these issues, this paper has proposed MCC architecture. We have divided this paper is into two parts, in the first part; we did comparative analysis of Web Service consumption on mobile devices using cloud and various parameters used. In second part we have proposed architecture for mobile Web Services in Cloud which compress response data using Gzip and use of web caching to reduce overhead of repeated or previously accessed Web Service.
