Low Power Consumption Solutions for Mobile Instant Messaging

Abstract:

Instant messaging (IM) services enable real-time text and multimedia exchange and online presence awareness. Users typically log onto instant messaging services persistently to discover available friends and also to be discovered. However, our analysis shows that the frequency exchange of presence information incurs massive power consumption to mobile devices over cellular or wireless local area networks. Such power consumption penalty can render persistent-instant messaging infeasible for battery-poweredmobile devices. In this paper, we propose several solutions to mitigate the power consumption problem. By reducing the network access and keeping mobile devices in the sleep mode as much as possible, these solutions achieve significant power saving. The power consumption of the proposed solutions is derived analytically in this paper and the proposed solutions are implemented using a

Jabber-based architecture. Actual power measurement results show that the power consumption of the proposed solutions agrees well with our analysis, and significant power saving can be achieved on mobile handsets with our low power consumption solutions

implemented.

Existing System:

            Instant messaging (IM) services, as have become arguably one of the most popular Internet applications nowadays, appeared as early as the introduction of the UNIX operating system, where users were able to exchange short messages using simple commands in real time. It is not, however, until the advent of ICQ (short for “I seek you”) that IM

began to gain wide popularity. Within only a few years, commercial IM applications such as AOL Instant Messenger(AIM), Microsoft MSN messenger (MSN), and Yahoo!

messenger, were released one after another with millions of registered users today . Typically, IM applications provide two main services: the instant message delivery

service and the presence awareness service. The instant message delivery service enables real-time text message exchange between users, while the presence awareness service provides the instantaneous online status of IMfriends/entities through the so-called “buddy list”. Originally, IM services are designed and tailored fordesktop use only. It is commonly realized that modifications to the existing IM services are necessary before IM can be widely accepted by mobile users [4]. Issues that have been identified for mobile IM include enhancement for presence awareness, security and support for location awareness, and the power consumption problem. To the best of the authors’ knowledge, however, the issue of power consumption caused by running IM on mobile devices has not been specifically addressed and solved. Sporadic data traffic on mobile devices leads to sever power consumption penalty. The occasional behavior of presence exchange with remote IM friends/entities thus poses a problem, which, as we show in this paper, can render persistent-IM infeasible for battery-powered devices.

Proposed System:

            Our goal is to to lower the power consumption of mobile devices due to the presence

information exchange. By effectively reducing the rate of the presence information exchange that mobile devices actually have to participate in, the proposed solutions are capable of achieving great power saving at zero cost. Further power saving can also be obtained on the mobile devices by compromising a certain amount of presence update delay.The tradeoff between the presence update delay and the attainable power saving is derived analytically

The proposed solutions are then implemented on both Wi-Fi and 3G handsets using a Jabber/Extensible Messaging and Presence Protocol (XMPP)-based architecture, based on which extensive power measurement experiments are performed. It is observed that our analysis is accurate in capturing the amount of power saving provided by the proposed solutions. By yielding an average presence update delay of 30 seconds, maximum power savings of 6.5 mA and 154 mA can be achieved for handsets over Wi-Fi and 3G networks, respectively. Concerning the battery capacity of mobile handsets, which typically ranges between 700- 1,500 mAh, our proposed low power consumption solutions can effectively extend the battery lifetime for mobileIMusers.
