A distributed cross-layer real-time routing in wireless sensor networks

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 distributed cross-layer routing mechanism to 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.
