Method for low-power transmission of big data information in wireless sensor networks

Abstract

The invention discloses a low power consumption transmission method for large data information in a wireless sensor network. According to the low power consumption transmission method for the large data information in the wireless sensor network, system power consumption is reduced by reducing overmuch control information during the transmission of large data, the number of data packets transmitted at one time is self-adaptively adjusted according to the number of wireless transmitted lost packets, accordingly a retransmission rate caused by data loss is reduced. The power consumption is reduced through a method of reducing the number of control information during transmission aiming at applications of large data information transmission in the wireless sensor network. The low power consumption transmission method for the large data information in the wireless sensor network has the advantages of firstly achieving a block transmission mechanism and reducing the number of control packet ACK (Acknowledgement character) and secondly being capable of calculating a packet loss rate of continuously transmitting the data last time according to the retransmitted field information in the ACK, self-adaptively adjusting the number of data for continuous retransmission next time andenablingthe purpose of reducing the data retransmission rate to be achieved.

Description

technical field [0001] The invention relates to the field of data transmission of a wireless sensor network, in particular to a method for low-power transmission of large data information in a wireless sensor network. Background technique [0002] In recent years, with the development of wireless communication and electronics, Wireless Sensor Networks (Wireless Senior Networks, referred to as WSN) has become a new network of research and application hotspots. It consists of a large number of micro sensor nodes deployed in the monitoring area. A multi-hop self-organizing network system is formed. However, the working environment of nodes is very complicated, so batteries are generally used for power supply, which leads to very limited energy of nodes, so how to reduce system power consumption and prolong the survival time of the network has always been one of the research focuses of wireless sensor networks. [0003] The energy of wireless sensor network nodes is generally l...
