    摘要： Provided is an operating method of sensor network. The operating method detects upper network nodes of a specific network node. The operating method detects link costs between the specific network node and the detected upper network nodes, respectively. The operating method detects a transmission and reception rate for the detected upper network nodes of the specific network node. The operating method selects one of the detected upper network nodes as a parent node of the specific network node, based on the detected link costs and the detected transmission and reception rate.

    摘要： Provided is a routing method capable of expanding a conventional tree routing to perform the efficient and safe key management in a sensor network environment that requires the symmetric key based key management. Each sensor node transmits a Route Reverse message to a sink node to set a reverse tree routing path. Therefore, it is possible to provide efficient and safe key management mechanism and communication environment by providing a bidirectional communication between a sink node and sensor nodes through an expanded tree routing such that a user is provided with a safe sensor network.

    摘要： Provided is a multi-route routing scheme that supports Quality of Service (QoS) in the wireless mesh network. A method of notifying about and avoiding congestion situation in data transmission in a wireless mesh network and a mesh node may also be provided. Data may be differentially transmitted to multiple routes by obtaining a route congestion level existing in a current multi-hop route and thus, data providing a real-time service, such as a video streaming service, may avoid congested routes and may be promptly transmitted. Multiple queues in a mesh node may be divided into divided queues based on a congestion situation of a transmission route in a network and the divided queues may be transmitted through multiple routes and thus, an efficiency of the overall network may increase.
