A wireless network management method for a wireless network is provided. A length parameter of a slotframe is evaluated by considering an advertisement requirement and/or a data transmission requirement of the wireless network. The length parameter of the slotframe is adjusted to be relatively prime to a total number of available channels. At least one timeslot within the slotframe is assigned for matching the advertisement and/or the data transmission requirements, and the timeslot assignment of the slotframe is advertised.

1. A wireless network management method for a wireless network, the wireless network management method including: evaluating a length parameter of a slotframe by considering an advertisement requirement and/or a data transmission requirement of the wireless network;adjusting the length parameter of the slotframe to be relatively prime to a total number of available channels, including adding a blank timeslot into the slotframe step by step, until the length parameter of the slotframe is relatively prime to the total number of available channels; andassigning at least one timeslot within the slotframe for matching the advertisement requirement and/or the data transmission requirement, and advertising a timeslot assignment of the slotframe. 2. The wireless network management method according to claim 1, wherein the length parameter of the slotframe includes a number of the timeslot(s) of the slotframe. 3. The wireless network management method according to claim 1, wherein the step of considering the advertisement requirement and/or the data transmission requirement of the wireless network includes: assigning at least one advertisement timeslot for a network management node and all managed nodes joined into the wireless network, respectively. 4. The wireless network management method according to claim 1, wherein the step of considering the advertisement requirement and/or the data transmission requirement of the wireless network includes: calculating respective data transmission requirement of each managed node based on respective data send from respective managed node. 5. The wireless network management method according to claim 1, wherein the step of assigning the least one timeslot within the slotframe includes: deciding that which of the timeslots within the slotframe is assigned for advertising, which of the timeslots within the slotframe is assigned for receiving, which of the timeslots within the slotframe is assigned for data transmission, and which of the timeslots within the slotframe is assigned for being blank, if necessary. 6. The wireless network management method according to claim 1, wherein in the slotframe, an advertisement interval, a data interval and/or a blank interval are interlaced. 7. The wireless network management method according to claim 1, wherein if the advertisement requirement and/or the data transmission requirement are changed, or a new managed node joins into the wireless network or an existing managed node is withdrawn from the wireless network, the timeslot assignment of the slotframe is updated and advertised. 8. A network management node for a wireless network, the network management node including: a timeslot requirement calculation sub-module, for evaluating a length parameter of a slotframe by considering an advertisement requirement and/or a data transmission requirement of the wireless network;a slotframe length adjustment sub-module, for adjusting the length parameter of the slotframe to be relatively prime to a total number of available channels, wherein the slotframe length adjustment sub-module adds a blank timeslot into the slotframe step by step, until the length parameter of the slotframe is relatively prime to the total number of available channels;a timeslot assignment sub-module, for assigning at least one timeslot within the slotframe for matching the advertisement requirement and/or the data transmission requirement, and advertising a timeslot assignment of the slotframe; andwherein the timeslot requirement calculation sub-module, the slotframe length adjustment sub-module, and the timeslot assignment sub-module are implemented by a processor. 9. The network management node according to claim 8, wherein the length parameter of the slotframe includes a number of the timeslot(s) of the slotframe. 10. The network management node according to claim 8, wherein the timeslot requirement calculation sub-module assigns at least one advertisement timeslot for a network management node and all managed nodes joined into the wireless network, respectively. 11. The network management node according to claim 8, wherein the timeslot requirement calculation sub-module calculates respective data transmission requirement of each managed node based on respective data send from respective managed node. 12. The network management node according to claim 8, wherein the timeslot assignment sub-module decides that which of the timeslots within the slotframe is assigned for advertising, which of the timeslots within the slotframe is assigned for receiving, which of the timeslots within the slotframe is assigned for data transmission, and which of the timeslots within the slotframe is assigned for being blank, if necessary. 13. The network management node according to claim 8, wherein in the slotframe, an advertisement interval, a data interval and/or a blank interval are interlaced. 14. The network management node according to claim 8, wherein if the advertisement requirement and/or the data transmission requirement are changed, or a new managed node joins into the wireless network or an existing managed node is withdrawn from the wireless network, the timeslot assignment sub-module updates and advertises the timeslot assignment of the slotframe.
