Patent ID: 8315278

Claim:
A method comprising: comparing at a first node an internal clock of the first node to synchronization information received from a second node; adapting the first node to the received synchronization information only when the received synchronization information indicates that the second node has a faster internal clock than the internal clock of the first node; setting a length of a next transmission period as a function of the comparing, and transmitting synchronization information only once during the next transmission period; wherein the length of the next transmission period is a function of the comparing and a number of corrupted receptions of synchronization information; wherein the length of the next transmission period is changed if, after a beacon period being in a reception state, the received synchronization information was not received or the received synchronization information was not correctly received; wherein the length of the next transmission period is shortened when the received synchronization information indicates that the second node has a slower internal clock than the internal clock of the first node; and wherein the length of the next transmission period is lengthened when the received synchronization information indicates that the second node has a faster internal clock than the internal clock of the first node.
