Joint power control, scheduling and real-time routing in wireless sensor networks

Abstract

increasing transmission power is an effective way to improve real-time data delivery in wireless sensor networks. On the other hand, increased power will also incur more interference though it can improve the link quality to increase real-time communication. So there is a tradeoff between interference and delay. In this paper, we consider a joint power control, scheduling and real-time routing problem, try to find a converged transmission power that can satisfy the on-line real-time data packet delivery and also we can achieve little interference by using TDMA scheduling. The simulation results show that our algorithms have better performance when compared with other related work.
