The present invention is directed to a method of selecting nodes in a multi-hop network having a combined coverage that reaches all the nodes in the network. These nodes called parent nodes, together with the root broadcast synchronization information regularly to the rest of the network. As part of the selection process, the parent nodes that would not interfere with each other are identified and then scheduled to broadcast synchronization information at the same time. Further, a time division structure can be used to control the access of these parent ...
1. A method for transmitting synchronization information in a multi-hop wireless network, the method comprising the steps of: selecting parent nodes in the network to transmit synchronization information to children nodes; and transmitting the synchronization information from the parent nodes in a number of channels, wherein the parent nodes being a predetermined number of hops from each other transmit in one channel; wherein the selecting of parent nodes includes: (i) receiving by a particular child node a first clock packet from a particular n...
