Abstract
A method and apparatus for use in an ad hoc network, comprising: a node transmitting an extended allowable hold time value to a further node; the node changing its transmission behavior such that the further node stops receiving transmission from the node for an extended period, for example by pausing transmission at least in the direction of the further node; and the further node treating the link to the node as intact during the extended allowable hold time. The transmitting of the extended allowable hold time value may be performed earlier than a next routine transmission of routine allowable hold time value would have been sent. The method may further comprise the node being instructed to maintain topology information for an extended time.
