Level control maintenance of temporal consistency in wireless sensor networks

With the development of wireless sensor network technology, more and more WSNs applications have the requirements of dealing with the critical mission. In this paper, we focus on the time critical problems of WSNs applications and design a new level control temporal consistency model with the priority tag. Then a Temporal Consistency Optimized Algorithm (TCO) is proposed to ensure that the packet will be delivered to sink before its lifetime is expected and schedule packets delivery according to their corresponding requirements. Finally, we analyze the performance of the TCO algorithm by theoretical derivation and experiment.
