Abstract
Systems and methods for group management in machine-to-machine networks are provided. Network nodes in a network group are divided into sub-groups and a group information register, which includes a listing of the nodes in the group, is divided into an equal number of partitions. The partitions are distributed to the sub-groups such that each node in a given sub-group receives the same partition. The partitions are accompanied by references to network nodes of other sub-groups (termed “anchor nodes”) that have a copy of another partition of the group information register. When a new network head takes over the network group, it is able to use the available partitions to determine which partitions are missing and which nodes hold copies of the missing partitions. The group head can wake up the missing nodes and obtain the missing partition copies, thereby generating a complete copy of the group information register.
