Patent ID: 7965678

Claim:
A method of controlling access by mobile users of a substantially infrastructureless communications network to a shared communication medium, wherein the shared communication medium is partitioned into a plurality of individual communication channels that can be individually exploited for communications between the network users, comprising: determining the existence of at least one main direction of movement of the network users, said main direction of movement being a direction around which directions of movement of a number of network users are clustered; associating a group of communication channels within said plurality of communication channels to the at least one main direction of movement; and reserving the communication channels of said group to the network users moving substantially in said main direction of movement, wherein the determining the existence of at least one main direction of movement includes: calculating a distribution of movement directions of at least neighboring network users of the network users that are clustered; analyzing the distribution, wherein the analyzing includes determining peaks in the distribution; calculating average velocity vectors for each main direction of movement by averaging the velocities of network users having direction of movement clustered around that direction of movement; calculating relative average velocities between the average velocity vectors; and validating each main direction of movement, provided that the relative average velocity thereof to the other average velocity vectors is not lower than a prescribed lower limit.
