Handling delay sensitive contents using adaptive traffic-based control method for minimizing energy consumption in wireless devices

Abstract

Transmission power control in mobile ad-hoc networks is a major issue for reliable end to end communication. Many researches have shown that the minimum transmission power that is required to keep the wireless network connected achieves the optimal throughput performance in wireless devices. By prolonging the network lifetime the overall performance substantially increases. Particularly when delay sensitive packets/multimedia streams are sent from a wireless device to another, the end to end communication must offer sufficient reliability and integrity. This paper describes a quantitative approach based on incoming traffic flow which bounds an asynchronous operation where each node evaluates dissimilar sleep-wake schedules. This scheme is entirely based on each node's incoming sleep-history traffic. Different sleep-wake schedules are continuously influenced for each node by packets and multimedia streams which are uniformly injected into the network. Simulation study is carried out for the energy conservation evaluation of the proposed model taking into account a number of metrics and estimation of the effects of incrementing the sleep time duration to conserve energy. Results show that the proposed method could be applied to infrastructure less networks to provide reliability for multimedia and delay sensitive packets without a significant increase in the power consumption.
