Abstract
It seems clear that information services have an almost unlimited potential in a wireless environment. Many of today’s “fixed” applications will continue to be useful in a mobile environment, and a variety of new services are certain to evolve for people on the move.
Since the energy conservation and the QoS guarantees are the major concerns in supporting heterogeneous data applications in mobile devices, the limited portable battery energy and the delay sensitivity of data services will also play important roles in the design of such transmission strategies. Therefore, intelligently using the knowledge about the traffic, channel, and network, we can design transmission strategies which are not only capable of extending the battery lifetime as much as possible, but also maintaining the agreed QoS.
In this thesis we combine the idea of smartly introducing communication delay from[15] and the threshold concept of [7], and try to find energy efficient transmission schemes that maximize system throughput, in which given different packet volume waiting to be transmitted, the system provides different service rates. According to the Queueing Theory, we preliminary model the system behavior into nonlinear mathematical programming problems. By maximizing the system throughput under the constraints of QoS requirements and the power limitation, we try to find the best transmission rate for different packet volumes.
