【摘要】 针对经典分簇算法能量负载不均衡的问题,提出了一种高效节能的跨层协议OCBC,在该协议中通过经线和纬线对网络进行划分,同时根据节点的地理位置和剩余能量来竞选簇首,以实现簇首的优化分布,使得能量消耗更加均衡。由于采用了优化的多跳算法,网络的扩展性得以较大的提高。仿真结果表明,动态分簇策略比传统的LEACH协议在网络扩展和生命周期方面有较大的性能优势。更多还原

【Abstract】 Aiming at the problem that the consumption of the classical clustering algorithm is imbalanced,this paper proposes one kind of highly effective cross-layer protocol OCBC(optimal cluster-head-distribution based on cross-layer algorithm).This protocol can optimize the distribution of the cluster-head by partitioning the network with longitudes and latitudes and decide cluster-head according to the position and remainder energy of the nodes.Due to the optimal multi-hop algorithm,the expansibility of the network can be improved greatly.The simulation results indicate that the dynamic clustering strategy has more advantages in expanding network and prolonging lifecycle than LEACH protocol.更多还原
