Abstract: In a self-organizing wireless multihop network, each node device selects operation among short-range (SR) and long-range (LR) communication modes, among which the SR mode uses a higher data rate than the LR mode. Each node device advertises connectivity link availability for neighboring node devices, and selectively initiates a link in response to connectivity availability advertised by at least one neighboring node device. The availability advertising is performed in the SR and the LR communication modes, according to a periodicity that is dynamically-variable in response to prevailing circumstances in the local neighborhood. The link initiation is selectively performed in one of either the SR or the LR communication mode based on selection criteria that include data throughput performance associated with different neighboring node devices with which connectivity is available via a certain communication mode.
