HSEP:面向无线传感器网络的异构感知分层稳定选举协议
HSEP: Heterogeneity-aware Hierarchical Stable Election Protocol for WSNs
摘要:
无线传感器网络(WSNs)正在增加,以处理复杂的情况和功能。在这些网络中,一些节点成为簇头(CH),负责聚集来自簇成员的数据并将其发送到基站(BS)。针对同构网络设计的分簇技术在能量消耗方面效率不高。稳定选举协议(SEP)引入了异构性的无线传感器网络,由两种类型的节点。SEP是基于每个节点的加权选举概率成为CH根据剩余能量的节点。我们提出了异构意识的分层稳定选举协议(HSEP)有两个层次的能量。仿真结果表明,HSEP的稳定期和网络生命周期,相比传统的路由协议,并具有更高的平均吞吐量比选定的分簇协议在无线传感器网络。
英文摘要:
Wireless Sensor Networks (WSNs) are increasing to handle complex situations and functions. In these networks some of the nodes become Cluster Heads (CHs) which are responsible to aggregate data of from cluster members and transmit it to Base Stations (BS). Those clustering techniques which are designed for homogenous network are not enough efficient for consuming energy. Stable Election Protocol (SEP) introduces heterogeneity in WSNs, consisting of two type of nodes. SEP is based on weighted election probabilities of each node to become CH according to remaining energy of nodes. We propose Heterogeneity-aware Hierarchal Stable Election Protocol (HSEP) having two level of energies. Simulation results show that HSEP prolongs stability period and network lifetime, as compared to conventional routing protocols and having higher average throughput than selected clustering protocols in WSNs.
