Research On Energy Saving Strategy Of WSN Based On RingGradation

With the rise of the Internet of things,wireless sensor network is widely used in var-ious fields,and it is mainly constructed by sensor nodes with certain wireless communi-cation ability through self-organization,and each sensor node sends effective information to the aggregation node.All the energy of sensor nodes is very limited,which restricts the further development and application of WSN.This paper focuses on the energy-saving strategy of WSN.energy consumption,improve the energy efficiency,and effectively prolong network lifetime.In view of the problem that the energy consumption of WSN is too large in idle time and the energy consumption difference between sensor nodes in sleeping and work-ing state,combined with the reasonable division of network area and the characteristics of WSN data transmission,this paper studies the node scheduling algorithm based on TDMA protocol in the data link layer,and analyzes and studies it step by step from linear network,multiline network and tree network,and uses mathematical induction The num-ber of time slots required for each network to complete a period of data transmission is proved by the method of EBR-RG,and a scheduling algorithm and a sleep strategy based on ring-gradation network are proposed.The simulation results of OMNET++ show that,compared with EBCR-RP,EBR-RG combined with scheduling algorithm and sleep strat-egy reduces the total number of packets by 8.9 % in terms of data volume,improves the performance by 31.29 % in terms of time slots,and reduces the energy consumption by 9% in terms of energy consumption.
