Abstract: Apparatus, systems, and methods disclosed herein operate to provide wireless communication between personal mobile communication (PMC) devices. An emulated wireless access point (AP) at a first PMC device (PMC1) establishes a first tunneled direct link setup (TDLS) session between a first station module (STA1) incorporated into the PMC1 and a second station module (STA2) incorporated into a second PMC device (PMC2). Following establishment of the TDLS session, the wireless AP is allowed to sleep; and most infrastructure management duties are handled by the STA1 during the session. PMC device battery charge may be conserved as a result. The emulated wireless AP may also establish a second TDLS link to a third station module (STA3) incorporated into a third PMC device (PMC3). The STA1 may then bridge data traffic flow between the STA2 and the STA3. Such bridging operation may enable communication between two PMC devices otherwise unable to decode data received from the other.

Abstract: Excessive latencies and power consumption are avoided when a large number of leaf nodes (LNs) contend simultaneously to join a time slotted channel hopping wireless communication network having a root node (RN) interfaced to LNs by one or more intermediate nodes (INs). A first plurality of shared transmit/receive slots (STRSs) is allocated for at least one IN, and a second plurality of STRSs is advertised for use by contending LNs, where the first plurality is larger than the second plurality. When a LN joins, its STRSs are re-defined such that most become shared transmit-only slots (STOSs) and no STRSs remain. The numbers of STRSs allocated to INs may vary inversely with their hop counts from the RN. One or more STOSs may be added for each of one or more INs in response to a predetermined network condition.
