Abstract
Routing technology at the network layer is pivotal in the architecture of wireless sensor networks. As an active branch of routing technology, cluster-based routing protocols excel in network topology management, energy minimization, data aggregation and so on. In this paper, cluster-based routing mechanisms for wireless sensor networks are analyzed. Cluster head selection, cluster formation and data transmission are three key techniques in cluster-based routing protocols. As viewed from the three techniques, recent representative cluster-based routing protocols are presented, and their characteristics and application areas are compared. Finally, the future research issues in this area are pointed out.

2 Overview of WSN clustering routing protocol In WSN architecture, the network layer routing technology has an important impact on the performance of WSN
From the perspective of network topology, we can roughly divide them into two categories Planar routing protocol and cluster routing the agreement
Summary
As a new information acquisition method and processing mode, Wireless Sensor Network (WSN) has become a research hotspot attracting much attention at home and abroad. WSN collects the information of the perceived objects in the network coverage area through a large number of sensor nodes deployed in the monitoring area, and provides the collected and processed information to end users through multi-hop wireless communication. WSN does not need fixed network support and is characterized by rapid deployment and strong destruction resistance. WSN can be widely used in military reconnaissance, environmental monitoring, medical monitoring, agricultural breeding and other commercial fields, as well as special fields such as space exploration and disaster rescue
