Abstract:
A position-based routing method by using a cell in a wireless sensor network is provided to minimize the energy and to determine a path until a destination node easily by reducing the periodical communication for the position information confirmation. In a next-hop position calculation process, the virtual ONI(Optimal Next-hop Information) among the paths until the destination node is calculated. In a communication area division process(302), the communication area is divided into fixed cell sizes by using the calculated virtual ONI position. In a packet broadcasting process(303), a packet including the virtual ONI position and the cell sizes is broadcasted to the surrounding node in the communication area. In a next-hop node decision process(305), the firstly transmitted surrounding node is determined as the next-hop node after receiving a response message in regard to the broadcasted packet from the surrounding node. In the next-hop position calculation process, the position joined by the virtual segment for connecting the distance until the destination node and a virtual circle corresponding to one's own communication area is calculated and the calculating result is determined as the next hop position.

Abstract:
A lower node connection method and a lower node connecting system capable of network connection to a lower node are provided to allow a network connection request of a lower node by excess of the limit of the lowest node. A network address which is set up about an upper node is altogether allocated in a lower node. The request is admitted for the excess of the lower node requesting the participation to the host node(801). A transmission message is received from the excess lower node. The received sending message is analyzed and the node transmitting the sending message is determined(803). The transmitted sending message is delivered to the determined node(804).

Abstract:
An efficient packet retransmission method and an apparatus in wire/wireless network are provided to increase the packet transmission ratio by reducing the number of overheads of an ACK(Acknowledgement) algorism and control packets if a receiver of the wire/wireless network requests to retransmit the packet. An efficient packet retransmission method in a receiver of the wire/wireless network is composed of steps for inspecting whether sequence ID(Identification) of a received packet is continued to the start or finish sequence ID of packets included in reception blocks with previously generated sequence ID of the received packet(S220); generating the new reception block by updating or deleting the reception blocks according to the inspection result by using the sequence ID of the received packet(S230); and transmitting an EBN(Explicit Block Negative Acknowledgement) requesting retransmission of the lost packets by a unit of block, if the inspection result is discontinuous(S240,S250).
Abstract:
A method for managing the data-traffic of node in a sensor network is provided to transmit data traffic in different timing by each node when traffic is simultaneously generated in several nodes with periodical data transmission and periodical polling, thereby reducing data loss. A method for managing the data-traffic of node in a sensor network comprises the following steps of: selecting an allocated network address and a topology depth by a user; computing transmission delay time using the allocated network address and the topology depth when traffic is generated from multiple adjacent nodes(S201,S202); and processing the traffic in sequence by timing according to the computed transmission delay time(S203). The transmission delay time is computed by multiplying the allocated network address by the topology depth.
