The scarcity of energetic resources in mobilecomputers is a very limiting factor. In this paper wepropose a solution that tries to balance energyconsumption and QoS requirements. Our solution followsan application-independent approach and, therefore, itcan be used concurrently, and without modifications, byany network application. Furthermore, our solution isindependent from the sub-network technology. Weimplemented this solution and we extensively tested it.Experimental results have shown that a relevant energysaving (about 70% on average) can be achieved withrespect to the legacy approach based on the TCP/IPprotocol stack. Furthermore, these savings are obtainedwithout a significant degradation in the QoS perceived bythe user. We also compared our application-independentapproach with an application-dependent one (i.e., asolution tailored to Web browsing) which performs(slightly) better. However, the application-independentsolution still guarantees significant savings, and fitsbetter a general-purpose mobile environment.
