routing paths in a wireless sensor network setting method and apparatus for performing it

摘要

The device is disclosed for performing routing path setting method and it's in a wireless sensor network. The routing path setting apparatus in a wireless sensor network comprises a destination node, the source node and the next hop node. Depending on the route from the node starts to transmit the packet, search for the first neighboring node and the first node if the destination is not contained in the neighboring nodes, the first neighboring node, the packet to the nearest node to the destination node of the transfers. As the next-hop node from the source node a packet is received, the search for the second neighboring node, and transmits the packet to the second closest node to the destination node or a destination node of the neighboring node. Accordingly, the hierarchical routing information on neighboring nodes by using a wireless sensor network, and searches the nearest By destination nodes where a packet is transmitted to the packet transmission, it is possible to reduce the number of hop count according to the packet transfer.
