Energy-saving clustering routing method based on network regional division and distances

Abstract

The invention relates to an energy-saving clustering routing method based on network regional division and distances. Aiming at the hotspot problem of a wireless sensor network, the invention provides an unbalanced clustering protocol (UCNDD) based on distances and network regional division; in the UCNDD algorithm design, an algorithm that the network regional division is combined with clustering is adopted; a ring node neighbour domain by taking a base station as the circle centre is defined at first; network division is carried out according to the distance between a node and the base station; the neighbour domain node is only used as a node contacting with the base station; nodes in other ranges perform an optimized clustering routing protocol; a cluster is established by adopting a timing mechanism; different competition radiuses of the nodes are set, such that the whole network has unequal clustering; and, in the selection of an information sending path, the next-hop node is selected by comprehensively considering the energy, the distance and the node degree information of cluster head nodes. By means of combination of the two mechanisms, the energy consumption of the whole network can be balanced better in an applied region; and thus, the life cycle of the network is prolonged.

Description

【Technical field】 [0001] The invention belongs to the technical field of combining computer applications and the Internet of Things. 【Background technique】 [0002] The wireless sensor network is composed of a large number of micro sensor nodes, which are deployed in designated areas and form a wireless communication network system through single-hop or multi-hop self-organization. This system is widely used in various physical Monitoring data in the environment, especially in harsh or special environments where people cannot get close to work normally. [0003] Those micro-sensor nodes are easy to deploy, but due to the disadvantage of limited energy, the application and development of wireless sensor networks are severely restricted. Therefore, in the research of many wireless sensor network systems, how to prolong the survival time of the network and balance the energy consumption of the network is an important goal. Many scholars have conducted a lot of research on more...
