一种多媒体传感器网络容错分簇算法

在无线多媒体传感器网络分簇算法设计中,针对如何满足QoS需求并尽可能提高能量效率问题,提出了一种容错分簇算法。根据节点的剩余能量和质心选举簇头,采用容错机制和能量有效策略组织成簇,并动态调整数据包在簇头间的传输速率。仿真实验结果表明该分簇算法满足多媒体数据传输的可靠性和实时性需求,能有效延长网络的生命周期。

Fault Tolerant Clustering Algorithm for Multimedia Sensor Networks

In the design of clustering algorithm for wireless multimedia sensor networks,aiming at how to meets the requirement of QoS in real-time and reliability domains as well as to improve the energy efficiency at the same time,an efficient clustering algorithm called Cluster-based Real-time Fault Tolerant Algorithm（CRF） was proposed.A node,according to its residual energy and the barycenter,independently makes its decision to compete for becom a cluster head.CRF automatically adjusts data packets transmission rate dynamically and features an energy-balance fault tolerant clustering policy.Simulation results show that CRF meets the requirement of QoS in real-time and reliability domains and can prolong the network life cycle.
