摘要:
Provided are a method and apparatus for efficiently performing routing in a wireless sensor network having a tree-hierarchical structure, the method and apparatus reducing the number of hops required for transmitting data. According to the method and apparatus, a node is determined as a proximal node from among nodes within range of a wireless signal of a transmission node, wherein the node is a node having the smallest difference from among differences between each of address values of the nodes within the range and an address value of a target node, and data is directly transmitted from the transmission node to the proximal node.

Provided are a coordinator, a gateway, and a transmission method for applying IPv6 in a wireless sensor network (WSN). Dual addressing of a link local address using a short address used in the WSN and a global unicast address using an extended unique identifier (EUI) of a node makes it possible to support mobility of the WSN and communicate data with an external network.
