Abstract

In distributed clustering protocols, the selection of a cluster head CH presents a major constraint to the proper functioning of the network. Generally, the process begins with a random choice of CHs at the time of cluster formation. A selective process is then used based on a probabilistic or iterative calculation in order to choose the different CHs. This approach leads to a non-uniform distribution of the different CHs. Indeed, in some cycles, the CHs may be concentrated in a part of the monitored area, some CH nodes fail to reach its neighbor CH. They are considered as isolated nodes in the network. The major contribution of this article is to propose a solution to maximize the number of nodes connected to the networks, in order to have an improved connectivity. However, the coverage of the entire monitored area can provide persistent information to WSN applications. The work in this paper resulted in the design and development of a new distributed clustering protocol called Orphan_Nodes_Connected (ONC) protocol that significantly improves the connectivity of the monitored area.
基于多跳集群的无线传感器网络路由协议中的孤儿节点连接管理
在分布式集群协议中,簇头CH的选择是网络正常运行的主要制约因素。一般来说,这一过程从星团形成时随机选择CHs开始。然后使用基于概率或迭代计算的选择过程来选择不同的CHs。这种方法导致不同CHs的分布不均匀。确实,在某些周期中,CHs可能集中在监控区域的一部分,一些CH节点无法到达相邻的CH,它们被认为是网络中的孤立节点。本文的主要贡献是提出了一种解决方案,以最大限度地增加连接到网络的节点数量,从而提高连接性。但是,整个监控区域的覆盖范围可以为WSN应用程序提供持久的信息。本文的工作导致了一种新的分布式集群协议的设计和开发,称为orphan_node_connected (ONC)协议,该协议显着提高了被监控区域的连通性。
