Abstract

In this study, we propose a novel optimal rate-oriented routing based on the Distributed Energy Usage Scheduling (DEUS) for mission-driven DSC applications. The proposed scheme adopts a new method called rate assignment instead of the traditional rate adaptation method in wireless networks to extend the network life time. The maximum network lifetime is achieved by constructing multiple rate-oriented paths between the source and sink, which balance the loads and lead to energy-efficient transmissions to meet the Distributed Source Coding (DSC) application needs. Present simulation has shown that the rate-oriented routing can extend the network life time and save energy significantly under the DSC application requirements.
