MEDIUM ACCESS CONTROL BASED ON RESERVERD ENERGY FOR WIRELESS SENSOR NETWORKS

摘要

The present invention relates to a channel competition technique of a wireless sensor network. The channel competition technique of the wireless sensor network includes a channel competition technique of a wireless sensor network including a sync node and a plurality of sensor nodes. Determining whether an event occurs within a sensing radius of the user; (b) collecting the information according to the event and measuring the remaining energy when the event occurs in step (a); and (c) the step (b). Setting a channel competition section according to the remaining energy measured in the step, (d) selecting a carrier sense time value, competing channels in the channel competition section set in step (c), and (e) obtaining a channel In one case, considering the remaining energy of the sensor node comprising the step of transmitting the information according to the event collected in the step (b) to the sink node. How is the channel competition.;According to the present invention, since the channel competition is made in consideration of the remaining energy of the sensor node, the life of the sensor node is extended, and thus the life of the entire sensor network is extended.;Sensor Network, Channel Competition, Sensor Node, Energy Balance
