Abstract

In this paper we propose a novel energy-aware QoS model, e-QoS, for application sessions that might across multiple protocol domains. The model provides the QoS guarantee by dynamically selecting and adapting application protocols. To the best of our knowledge, our model is the first attempt to address QoS adaptation at the application session level by proposing a new QoS metric called session lifetime. To show the effectiveness of the proposed scheme, we have implemented a case study: instant messenger applications between two PocketPCs. Experiment shows that the session lifetime has been successfully extended to the value negotiated by two PocketPCs with very diverse battery capacities.
