    Abstract: Provided is a firmware updating method for a new node in a wireless sensor network including a plurality of nodes. The firmware updating method for the new node (a) a new node searching for neighbor nodes located within a predetermined distance; (b) the new node designating a parent node among the searched neighbor nodes; (c) in the case where the plurality of nodes include a join receiving state for joining the new node to the wireless sensor network, the designated parent node and the new node establishing a communication link by using the join receiving state; (d) the parent node transmitting firmware to the new node through the established communication link; and (e) the new node receiving the firmware from the parent node, updating existing firmware with the received firmware, and driving the updated firmware to be jointed to the wireless network. In the case where the new node is to be joined to the wireless sensor network, it is possible to directly update the firmware of the new node on the spot without recalling the node to a factory.

    Abstract: A routing method of a wireless network system is provided. Paths of the wireless network system are divided into down-stream and up-stream paths. The up-stream paths are reset for each period, or whenever a network is changed, or whenever transmission of data fails more than a predetermined number of times. Accordingly, it is possible to secure an average lifetime of a wireless network system by previously preventing a bottleneck from occurring at a specific node, increase a transmission speed of data by reducing the hop count to the sink node connected to the information collector, and reduce power consumption of a battery.

    Abstract: A recording medium for storing virtual deletion information, and recording and/or reproducing method and apparatus therefor are provided. The recording medium includes a first region having a plurality of still pictures, and a second region having first virtual deletion information for the still pictures, and still picture group information for separating the still pictures in the first region into a predetermined maximum number of groups in order to manage the still pictures at a group level, wherein the first virtual deletion information is within the still picture group information, and if the first virtual deletion information is set to a virtual delete state, the corresponding still picture is not to be reproduced. Accordingly, file extent information can be prevented from excessively increasing by maximally preventing a recording area from being scattered, when some of a data file are deleted by a user's request.
