    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.

    摘要: A method for supporting handoff and preventing data loss in mobile communications networks is provided. The method for a mobile node establishing a mobile Internet protocol (MIP) with at least one or more wireless packet service systems, each of which has a serving GPRS support node (SGSN) and a gateway GPRS support node (GGSN), includes: a first SGSN connected to the mobile node transmitting predetermined first connection information on the mobile node to at least one or more second SGSNs adjacent to the first SGSN; the second SGSN receiving the first connection information storing the first connection information as a database item, and transmitting 1 first connection acknowledgement message to the first SGSN; if reception of the connection acknowledgement message is successful, the first GGSN connected to the first SGSN transmitting predetermined second connection information on the mobile node to at least one or more second GGSNs connected to the second SGSN; and the second GGSN receiving the second connection information and then transmitting a second connection acknowledgement message to the second GGSN. By transmitting information on a mobile node required for handoff to adjacent foreign agents (FAs) in advance, when handoff is performed, reliable handoff can be performed quickly without resetting and releasing a PPP, such that IP mobility services can be provided.

    摘要: A router relays sensing data between a field network including at least one sensor node and a plant network including a management system. The routing apparatus manages a routing table in which a next address and an output interface corresponding to an extension destination address of 6 bytes and an input interface are stored and transmits sensing data to another field network or a management system using the routing table.
