The list of MPR nodes includes neighbor nodes that cover each of the plurality of nodes within two hops. A first set of nodes is identified that is not already in the list of MPR nodes. In a first approach, the first set of nodes includes nodes that are the only neighbor node to a node in the list of MPR nodes. In a second alternative approach, the first set of nodes includes nodes that are sequentially previous to a node in the list of MPR nodes. Once the first set of nodes is identified, the first set of nodes is added to the list of MPR nodes. If the first approach is used, the method further comprises identifying a second set of nodes that is not already in the list of MPR nodes. The second set of nodes comprises nodes that have the largest number of neighboring MPR nodes. The second set of nodes is then added to the list of MPR nodes. | 2009-07-30 |
20090190515 | BRIDGING WIRELESS AND WIRED MEDIA IN A COMPUTER NETWORK - In one embodiment, a transmitting node may be configured to transmit a wireless advertisement frame over a computer network, wherein the frame includes a source address of a reachable node being advertised, a destination address to which the reachable node is to be advertised, a transmitter address of the transmitting node, and a receiver address of a wireless access point to which the wireless advertisement frame is to be received. Also, the wireless access point may be configured to receive the wireless advertisement frame from the network, and in response, transmit a reflected wireless advertisement frame having the source address of the reachable node, the destination address to which the reachable node is to be advertised, a transmitter address of the access point, and a receiver address that indicates the reflected frame is to be accepted by any appropriate receiver excluding the transmitting node. | 2009-07-30 |
