摘要：
Delay requirement becomes a key problem for the time sensitive applications in wireless sensor networks besides the power conservation issue. This paper proposes a novel Network Utility Maximization (NUM) model with constrained delay for real-time applications in wireless sensor networks. By using dual decomposition techniques, we present a distributed iterative price and rate adaption algorithm which converges to the global optimal solution. The presented algorithm can jointly control congestion and contention while meeting the delay requirement ...
