Abstract

Based on the principle of cluster wireless sensor network, this article introduces typical routing protocols in wireless sensors, and wireless sensor network protocol in detail analyzes their advantages and disadvantages and addresses their shortcomings. First, in the clustering network, a uniform clustering protocol with multiple hops in the circular network is proposed. The circular network is divided into rings of equal width, and clusters of equal size are set on different rings. Secondly, the ordinary nodes on each layer of the ring send the collected data to the auxiliary intelligent nodes in the cluster in a single-hop manner, and the auxiliary intelligent nodes located on the outer ring transfer the data to the auxiliary intelligent nodes located on the adjacent inner ring. Finally, on the basis of studying the clustering network protocol, this paper proposes a new clustering routing algorithm, a multihop adaptive clustering routing algorithm. The simulation results show that the algorithm can effectively extend the life of the network, save network energy consumption, and achieve network load balance. At the same time, the initial energy of the auxiliary intelligent node is set according to the energy consumption of the ordinary node and the relative distance between the auxiliary intelligent node and the base station on each layer of the ring. The theoretical and simulation results prove that, compared with the clustered network and auxiliary intelligent nodes, the clustered network can extend the life of the network.

Highlights

  • Wireless sensor networks (WSNs) are composed of a large number of sensor nodes, which are deployed in the target area to be monitored

  • Because as the number of auxiliary intelligent nodes on the second-level ring increases, R1 will decrease that is, the farthest distance between ordinary nodes and auxiliary intelligent nodes will decrease, reducing the number of ordinary nodes sending to the cluster head

  • An energy-efficient clustering protocol is proposed in the wireless sensor network

Summary

Introduction

Wireless sensor networks (WSNs) are composed of a large number of sensor nodes, which are deployed in the target area to be monitored These nodes cooperatively perceive and process the information in the monitoring area; that is, they can be used to obtain the information of the objective physical world [1]. It has been widely used in military, environmental, and habitat monitoring and forecasting, smart home, fire detection, machinery monitoring, industrial and agricultural control, remote control of dangerous areas, and urban transportation in many fields in recent years. A wireless sensor network has many advantages such as fast and flexible networking, has high research value and very broad application prospects, and has attracted great attention from academic and industrial circles [7,8,9]
