On the Impact of Caching and a Model for Storage-Capacity Measurements for Energy Conservation in Asymmetrical Wireless Devices

Traffic and channel-data rate combined with the stream oriented methodology can provide a scheme for offering optimized and guaranteed QoS. In this work a stream oriented modeled scheme is proposed based on each node's self-scheduling energy management. This scheme is taking into account the overall packet loss in order to form the optimal effective -for the end-to-end connection- throughput response. The scheme also -quantitatively- takes into account the asymmetrical nature of wireless links and the caching activity that is used for data revocation in the ad-hoc based connectivity scenario. Through the designed middleware and the architectural layering and through experimental simulation, the proposed energy-aware management scheme is thoroughly evaluated in order to meet the parameters' values where the optimal throughput response for each device/user is achieved.Comment: IEEE Communication Society (COMSOC), 16th International Conference on Software, Telecommunications and Computer Networks (SoftCOM 2008), September 25 & 26 2008, "Dubrovnik", September 27, Split and Dubrovnik, pp. 243-24

Performance Measures of Stream-Oriented Power Consumption for Asymmetrical Communication in Wireless Ad-Hoc Networks

Power consumption control in mobile ad-hoc networks is one of the most important issues for enabling a guaranteed quality of service in end-to-end transmissions. However recent power consumption control techniques have not yet associated the power control of a wireless device with the content delivery. This means that all transmissions are treated in the same way, which is disastrous in the case of delay sensitive contents in end-to-end connections. In this work the packet stream of a delay sensitive content is modeled and associated with the prioritization of the packets and their spatiotemporal delays. Depending on each stream's characteristics at a certain time, a nonlinear communication model is proposed. Adjacent-neighboring nodes with certain transmission power associate their data delay with nodes' capacity measures during data revocation. Following a real time scenario each node has fading characteristics in an entirely asymmetric communication. Performance evaluation results show the efficiency of the proposed model as well as its capabilities under different fading condition
