Appeal No. 2006-1957
Application No. 10/301,394
The claimed invention relates to a wireless network including a cluster head
network and a sensor/actuator network with the sensor/actuator network arranged in a
hierarchical manner with the cluster head network. The cluster head network includes
at least one cluster head and the sensor/actuator network includes a plurality of
sensor/actuator nodes arranged in a plurality of node levels.
Claim 1 is illustrative of the invention and reads as follows:
1. A wireless network, comprising:
a cluster head network having a plurality of cluster heads; and
a sensor/actuator network arranged in a hierarchical manner with the cluster
head network and having a plurality of sensor/actuator nodes arranged in a plurality of
node levels and being self-organizing;
wherein information about an entire sensor/actuator network topology is
maintained at each of the cluster heads in a time synchronized manner and all
sensor/actuator nodes are synchronized with respect to the cluster head network.
