Method for topology control using sectorized antennas in wireless networks

摘要

The invention concerns a method for optimizing antenna pattern assignment for a first wireless communication device forming a wireless network with at least one second wireless communication device, each of said communication device being equipped with a multi-sector antenna, an antenna pattern being a combination of said antenna sectors, said communication devices being adapted for sending a request and for receiving a response using a current antenna pattern assignment, said method comprising a step of:
evaluating by said first communication device a first value;sending by said first communication device to said second communication device a broadcast request comprising said valuereceiving by said first communication device, a response to said broadcast request, said response being sent by said second communication device, said response depending on a second value evaluated by said second device;Switching or not, by said first communication device, to a new antenna sector assignment depending on said response;
According to the invention the first value is evaluated by minimizing a first local function according to the received signal strength received by said first communication device having said current antenna pattern assignment and the second value is evaluated by minimizing a second local function according to the received signal strength received by said second communication device for its own current antenna pattern assignment.

1. A method for antenna pattern assignment for a communication device equipped with a multi-sector antenna including multiple sectors, the multi-sector antenna configured to allow the multi-sector antenna to be used with a plurality of antenna pattern assignments, the method comprising:
sending, by the communication device, a broadcast request using an antenna pattern assignment of the plurality of antenna pattern assignments including one or more sectors of the multiple sectors; receiving, by the communication device, a response to the broadcast request; and switching, by the communication device, to a new antenna pattern assignment of the plurality of antenna pattern assignments based on the response, setting, by the communication device, a timeout depending on a date of sending the broadcast request, wherein the switching comprises switching, by the communication device, to the new antenna pattern assignment if the response received by the communication device within the timeout is positive.
