摘要：Multimedia messaging in instant messenger (IM) application (app) usage has become increasingly popular on smartphones today. Sharing of multimedia messages such as images, web links, videos and audio messages has become prevalent on smartphones. The IM app causes smartphone battery to drain owing to its intensive data upload / download operations when users share multimedia messages. This work focus on instant messenger app performs upload / download to share multimedia message impact on a smartphone battery. Our collected data shows that IM users share a large number of redundant multimedia messages with server side and also existing in local storage. A redundant network traffic directly can increase access wireless network (3G or Wi-Fi) usage and leading to high energy consumption in a smartphone. This paper proposes an energy efficient multimedia message sharing scheme to prevent redundant network traffic. The underlying principle of the proposed design is verifying hashes of shared multimedia messages prior to an instant messenger application uploading or downloading them. Our evaluation shows that our proposal saves up to 60 % of energy consumption.
