METHOD FOR SELECTING SERVING PNC BASED ON FER IN WIRELESS MESH NETWORK
First Claim
1. A method for selecting a serving piconet coordinator (PNC) at a wireless device in a wireless mesh network, comprising:
- selecting an initial PNC if data is generated to transmit in a data transceiving preparation state;
deciding an initial MAC frame size for transmitting/receiving a packet to/from the selected initial serving PNC and performing data communication with the selected initial serving PNC;
reselecting a PNC having a best channel state from PNCs in a same coverage as a serving PNC after selecting the initial serving PNC, regularly;
deciding a MAC frame size for transmitting/receiving a packet to/from the reselected serving PNC and performing data communication with the reselected serving PNC if the serving PNC is reselected; and
terminating the data communication if a frame error rate (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.

Abstract
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.
