Patent ID: 8213349

Claim:
A method of optimizing the orientation of a receiving antenna of a recipient node, in a mesh communication network comprising a plurality of sending nodes and using a time division multiple access (TDMA) protocol in which each sending node is allocated to a predetermined time slot, said recipient node receiving a plurality of redundant copies of the same item of data sent by the sending nodes, wherein said method comprises steps of: determining a first set of antenna angles to be used by said receiving antenna to capture data respectively sent by each of the sending nodes of the network; receiving data sent by each of said sending nodes using the respective antenna angle of said first set of antenna angles; performing at least one operation of correlation between the various redundant copies of the same item of data, received by the recipient node; on the basis of said correlation operations, determining at least one redundant copy that is unnecessary for the decoding of the data received during the receiving step; determining at least one time slot during which said at least one redundant copy that is unnecessary for the decoding is received; and during said at least one time slot, updating the antenna angle used by said receiving antenna to receive data sent by the sending node allocated to said time slot.
