  • Routing method and wireless network system
    Patent number: 8208485
    Abstract: A routing method of a wireless network system is provided. Paths of the wireless network system are divided into down-stream and up-stream paths. The up-stream paths are reset for each period, or whenever a network is changed, or whenever transmission of data fails more than a predetermined number of times. Accordingly, it is possible to secure an average lifetime of a wireless network system by previously preventing a bottleneck from occurring at a specific node, increase a transmission speed of data by reducing the hop count to the sink node connected to the information collector, and reduce power consumption of a battery.
