Abstract: 본발명은 USN의데이터송/수신장치및 그방법에관한것으로, 다양한센서노드를수용한센서네트워크의 MTU값을결정하고, 하나의센서노드를통해생성된이미지정보에해당하는단편화된패킷들을출발지노드에서이웃노드를통해목적지노드까지, 즉단 대단으로실시간송/수신함으로써, 기존에서와같이단편화된패킷에대한재송신기능등이정의되어있지않아데이터송신에따른소요시간이상대적으로길어지고이로인하여실시간서비스에치명적인요소가되는문제점을해결할수 있다. 또한, 본발명은센서네트워크에서이미지정보와같은대 규모데이터를멀티홉으로실시간송/수신하므로목적물의정확하고빠른인지를보장한다.

Abstract: A wireless sensor network having a hierarchical structure and a routing method therefor are provided to hierarchically configure a network and optimize a cross layer, thereby realizing scalability of the network and guaranteeing end-to-end transmission delay. A network having a hierarchical structure is included in a plurality of clusters(1). Each cluster comprises a plurality of nodes(3) and a cluster head(2). The cluster head is connected to the nodes in a mesh type. Each node is connected to another cluster through a cluster head of a corresponding cluster. Each node determines a next hop through information included in a message received from a network layer.

Abstract: PURPOSE: A data transceiver of USN and a method thereof are provided to transceiver simplified packets which are generated through one sensor node and to accurately recognize a target due to transceiving data in multi-hop network. CONSTITUTION: A main MCU(10) includes an MTU(Maximum Transmission Unit)(11), an application unit(13), a routing unit(15), and an MAC(Medium Access Control) unit(17). The main MCU performs a routing function and a network function. The application unit supplies an activation signal in order to operate a camera driving MCU(20). The routing unit combines a simplified packet.
