Based upon clustering LEACH algorithm,a QBL(QoS-based LEACH)algorithm is proposed in this article aiming at improvement in energy saving,network delay,life time and reliability.The QBL algorithm,armed with new algorithm of weighting in selecting cluster head as well as uneven clustering strategy,has only part of members within the cluster to be assigned to fulfill monitoring tasks,and adopts shortest path of weighting methods in inter-cluster communication.Simulation results show that the QBL algorithm has turned out remarkable performance in improving network delay,lifetime and reliability in simulation experiments.
