Clustering and routing method of wireless rechargeable sensor network

Abstract

The invention discloses a clustering and routing method of a wireless rechargeable sensor network. In consideration of influences of the characteristic, that mobile wireless energy supply / data collection equipment WCE in the wireless rechargeable sensor network can collect data and replenish energy to nodes, on network energy distribution and routing, the k-Means-based clustering and routing method of the wireless rechargeable sensor network is provided and includes three phases of initialization, cluster construction and data transmission. The clustering and routing method has the advantagesthat on the condition of knowing the charging path of the mobile wireless energy supply / data collection equipment WCE, the charging radius of the mobile wireless energy supply / data collection equipment WCE, current residual energy of senor nodes and distances between the sensor nodes and fixed stations are considered for clustering, and network routing schemes are optimized.

Description

technical field [0001] The invention relates to the field of wireless rechargeable sensor network methods, in particular to a wireless rechargeable sensor network clustering routing method. Background technique [0002] Wireless Rechargeable Sensor Networks (WRSNs) is a new type of sensor network that introduces wireless power transfer technology into traditional wireless sensor networks (Wireless Sensor Networks, WSNs). In recent years, how to design a clustering routing strategy so that the entire network does not die, the energy in the network tends to be balanced, and the energy efficiency of the network is significantly improved is a problem worth studying in the application of WRSNs. [0003] At present, most of the researches on the clustering routing protocol are used in WSNs, and there is no report on the clustering routing algorithm of WRSNs so far. At the same time, there are mobile wireless energy supply / data collection devices in the WRSNs network, which can su...

Problems solved by technology

[0003] At present, most of the researches on clustering routing protocols are used in WSNs, and there is no report on clustering routing algorithms for WRSNs so far.

At the same time, there are mobile wireless energy supply / data collection devices in the WRSNs network, which can replenish energy for sensor nodes and collect data information of sensor nodes, which affects the node energy and data transmission paths of the network, so the clustering routing protocol in WSNs is in Not applicable in WRSNs
