摘要:
A method for enhanced power saving on DCF based wireless networks is disclosed. The method divides a beacon transmitting section in an Announcement Traffic Indication Message (hereinafter, referred to as “ATIM”) window period defined by IEEE standard 802.11 according as there is a data packet to be sent or not and allows a terminal that has received the beacon to go to a doze state immediately according to beacon reception timing, thereby preventing unnecessary power consumption.

A method for power saving routing in wireless networks is disclosed. The present invention calculates a distance to a destination node to select and estimate candidate nodes so as to reduce the amount of calculations in the event of routing. Furthermore, the invention repeats the algorithm by optimum value n so that accessibility to the destination node can be obtained. This enables more efficient routing.

The present invention relates to a directional flooding method in a wireless sensor network. Transfer of a packet between respective sensor nodes and a sink node in a wireless sensor network is made with the directivity. To this end, when the packet is transmitted from the sensor nodes to the sink node, only the sensor nodes having a minimum hop count for the sink node are involved in transmission of the packet. Meanwhile, if the packet is sent from the sink node to the sensor nodes within a given destination area, after the packet reaches a corresponding destination area, only sensor nodes located within the destination area transmit the packet. The present invention has an effect that it can improve energy consumed on average and a total number of packets transmitted when transmitting the packets in a wireless sensor network compared to a conventional simple flooding method.

Disclosed is a method for producing extruded noodles including mixing noodle materials; kneading the mixed noodle materials and mixing water into dough and gelatinizing the dough through a first extruder; cooling the gelatinized dough to a temperature of 40° C. or less; extruding strips of noodles from the gelatinized dough through a second extruder; cutting the extruded strips of noodles; putting a designated amount of the cut strips of noodles into a mold so as to mold the noodles; firstly drying the molded noodles at a temperature of 40˜70° C. under a relative humidity of 20% or more for 1˜20 minutes; and secondarily drying the firstly dried noodles at a temperature of 60˜100° C. for 30˜60 minutes. The dough is gelatinized through the first extruder without using a separate mixer, and then continuously passes through the second extruder without applying heat, thereby having an increased uniformity and allowing the extruded strips of noodles to be easily separated from each other. Further, since the drying of the noodles is divided into two steps, the extruded noodle producing method increases the disentangling property of final products of the extruded noodles in cooking, reduces the ingredient elution amount of the noodles, and prevents the generation of cracks of the noodles, thereby providing noodles, which have stability and convenience in circulation, storage, and cooking so as to be easily handled, and have excellent appearance and texture after cooking.
