本文提出了一种用于无线传感器网络的新型组播路由协议,称为具有修剪和能量平衡的组播树协议(MPEB),通过高效、低功耗的分层组播树传播数据。通过剪枝算法和能量平衡算法,MPEB可以节省能量并平衡负载。剪枝算法记录并维护每个子节点的备份父节点,从而可以将可能的节点从多播树中分离出来,并使尽可能多的节点进入休眠状态。能量平衡算法可以保护低功率节点不会耗尽能量而死亡,从而平衡整个网络的总能量消耗,延长网络的生命周期。正式的验证和模拟评估了MPEB的性能,这表明MPEB在降低和平衡能耗方面比其他方法具有明显的优势。
This paper presents a novel multicast routing protocol for wireless sensor networks, named Multicast tree protocol with Pruning and Energy Balancing (MPEB) to disseminate data through a layered multicast tree with high-efficiency and low-power consumption. With pruning algorithm and energy balancing algorithm, MPEB can save energy and balance load. Pruning algorithm records and maintains backup parents for each child node, and thus it can detach possible nodes from the multicast tree and turn as many nodes as possible to sleep. Energy balancing algorithm protects nodes with low power from running out of energy and dying out, and thus it can balance total energy consumption of the whole network and prolong the network lifetime. The formal validations and simulations evaluate the performance of MPEB, which shows that MPEB has a distinct advantage over others in both reducing and balancing energy consumption.
