摘要： Provided is a method for selecting a serving PNC at a wireless device in a wireless mesh network for data communication. In the method, an initial PNC is selected if data is generated to transmit. Then, an initial MAC frame size is decided and data communication is performed with the selected initial serving PNC. A PNC having a best channel state is reselected from PNCs in a same coverage as a serving PNC after selecting the initial serving PNC. A MAC frame size is decided for the reselected serving PNC and data communication with the reselected serving PNC is performed. The data communication is terminated if a FER of the reselected serving PNC is larger than a maximum allowable FER or if there is no data to transmit after the data communication is performed.

摘要： The present invention relates to a method of estimating the position of a mobile node in a wireless sensor network using a passive mode OWR method. The method includes: estimating frequency offsets of anchor nodes and a mobile node; allowing the anchor nodes to sequentially transmit ranging frames; allowing the mobile node to receive the ranging frames and to estimate the difference between the reception times of signals from two anchor nodes; and applying the estimated difference between the reception times of the signals to time difference of arrival (TDOA) to estimate the position of the mobile node. According to the above-mentioned structure of the present invention, a plurality of mobile nodes can estimate their positions with a minimum number of ranging frame transmissions, without using a separate network synchronization unit. In addition, it is possible to easily construct a wireless sensor network for position recognition, and rapidly and accurately perform distance estimate using an OWR method.

摘要： There is provided a method for estimating a position of a mobile node in a wireless sensor network. The method includes estimating a frequency offset between anchor nodes and estimating a difference between times when ranging frames from a mobile node are received by two anchor node, without use of a separate synchronization unit, such as a network synchronized clock supply unit that supplies a network synchronized clock via a cable, in a wireless sensor network, unlike a conventional method of estimating Time of Flight (TOF) using Two-Way Ranging (TWR) and Symmetric Double Sided-TWR (SDS-TWR) schemes. The estimated receiving time difference is directly applied to a Time Difference Of Arrival (TDOA) algorithm in order to estimate the position of the mobile node.
