The Design And Implementation Of Mobile Social IM Software Based On MQTT Protocol

Software associated with social mobile IM increasingly appear in the mass market,it meets the diverse needs of the growing.In different with the traditional PC,such software and other resources for electricity flow requirements more stringent,and the design is also more fitting concept of mobile network.Traditional text-based protocol is difficult to adapt to mobile network environment,and this kind of protocol is also waste of power and network traffic.Proposal in this paper is aim to solve this problem.The main work of this paper includes:(1)In terms of messaging,this paper develops from the ground up to achieve the MQTT qosO protocol and qos1.The application layer enhances logic control to ensure the reliability of the message.(2)In terms of functions to achieve,for the realization of cross-searching friends and ensure data consistency,we use a Redis "master-slave"+"double write" architectural approach.At the same time,this paper implements web module that associated with http request with Play framework.This paper aims to propose IM software solution that suitable for mobile network.It integrates into the social elements,and at the same time gives data consistent solution.Experimental results show that the solution can achieve good results.
