DEVICE AND METHOD FOR A MULTI-HOP MOBILE AD HOC NETWORK

摘要

An ad hoc network comprises a plurality of self-organized clusters (C1,C2) of nodes (N1 -N5), i.e. one-hop ad hoc subnetworks. Any node can assume the role of a routing node (N3,N4) if it is able to communicate with at least one node in another cluster (C1,C2) so as to self-organize the clusters of nodes into a multi-hop ad hoc network. An intra-cluster synchronization of sleep and awake periods of nodes in a power-saving mode of operation is performed separately within each cluster. An inter-cluster synchronization of awake periods of neighboring clusters (C1,C2) to be temporally non-overlapping is per¬ formed by means of the routing nodes (N3,N4).
