상기 탐지 정보를 전송하기 위한 소스 노드는 우선적으로 싱크 노드의 존재와 위치를 파악하기 위해 Hello 메시지를 전송한다. 싱크 노드는 Hello 메시지를 수신한 후 수신한 모든 Hello 메시지에 대하여 Hello 메시지를 재전송한다.

Abstract: A method and an apparatus for setting a routing path in a wireless sensor network are provided to remove a long transmission path problem during data transmission only through an existing address allocation method and communication between a parent device and a child device without using a separate message for searching an existing path. A search unit searches existence of a destination address indicating an address of a receiving device receiving transmission data, a parent address of the destination and an ancestor address of the destination. When an address is searched in the search unit, an LQI(Link Quality Indicator) determiner transmits the data to the receiving device if an LQI value of the address exceeds a preset value.

Abstract: An energy saving method in a mobile network for minimizing the consumption power of each node is provided to minimize the activation period in a normal time, save poser and minimize the amount of power consumption by lengthening a transmission activating period. A source node receives WN(Wakeup Notification) from a target node(S702). The source node determines whether the activating period is sufficient for data transmission(S703). If the activation period is sufficient in data transmission, the source node transmits data frame within the activation period(S704). If the activation period is not sufficient, the source node requests the activation period extension(S705). The source node determines EREP(Extension REPly) reception according to the activation period extension(S706).

Abstract: A wireless sensor network using the dynamic message transmitting method and a control method thereof are provided to improve the throughput per node and remove the necessity of an MAC(Media Access Control) layer by calculating/updating the message relay probability of each sensor node and dynamically determining a node for relaying a message based on the calculated result. A destination node broadcasts a beacon signal to nodes within a network. A transmission node sends a transmission request message to neighboring nodes to select a relay node for relaying a message, receives response messages from the neighboring nodes which determine a response based on the relay probability, and then selects the relay node based on the response messages. The relay node receives the beacon signal, measures the strength of the beacon signal, and then transmits a response message including information about the strength to the transmission node.

Abstract: A multi-path routing method is provided a multi-path routing method for selecting appropriate multiple paths when information sensed from a source node is transmitted to a sink node in wireless sensor networks. The source node for transmitting the sensed information first transmits a Hello message to the sink node to identify the existence and position of the sink node. The sink node receives the Hello message and then re-transmits the Hello message with respect to all the received Hello messages. Respective middle nodes accumulate distances between the middle nodes while the Hello message is transmitted to the source node through a reverse path of the Hello message, and all the middle nodes maintain a real distance from the sink node. The source node receiving all the Hello messages can rout a plurality of appropriate paths through Hop-by-hop to the sink node by providing respective weights to an energy remaining amount, an appropriate transmission radius and a real distance from the sink node. Accordingly, priorities can be provided to lifetime of the source node, average energy consumption and the shortest path by adjusting the respective weights when routing the plurality of paths. In addition, appropriate paths can be routed considering the transmission success rate of a path, and a load balancing effect can be obtained using path cost.
