Sensor network for transmitting data and data transmitting method thereof
First Claim
1. A sensor network comprising:
- one or more sensor nodes that collect target data and transmit the collected target data at an allocated sub-time slot among sub-time slots constituting each time slot corresponding to the collected target data; and
a gathering node that allocates the sensor nodes with the sub-time slot for each of the time slots, and receives the collected target data transmitted by the sensor nodes.

Abstract
Disclosed are a sensor network for transmitting data and a data transmitting method thereof. The sensor network includes one or more sensor nodes for collecting target data and transmitting the collected target data at an allocated sub-time slot among sub-time slots constituting each time slot corresponding to the collected target data, and a gathering node for allocating for the sensor nodes a sub-time slot for each of the time slots, and receiving the collected target data transmitted by the sensor nodes. Data transmission by bits reduces power consumption and does not require additional information transmission to prevent data collision. Therefore, power consumption is minimized and a plurality of sensor nodes possibly transmit data at one time, accordingly shortening transmission time.

8. A data transmitting method of a sensor network which includes a sensor node for transmitting collected target data and a gathering node for receiving the data transmitted by the sensor node, the data transmitting method comprising:
-
transmitting, from the sensor node, the collected target data at a sub-time slot allocated among sub-time slots constituting each time slot corresponding to the collected target data; and
allocating the sub-time slot to the sensor node for each time slot and receiving, at the gathering node, the collected target data transmitted by the sensor node. - View Dependent Claims (9, 10, 11, 12, 13, 14)
