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.

Abstract: A method of transmitting association requests in a wireless sensor network includes transmitting an association request from a leaf node to an intermediate node. The method further includes transmitting the association request from the intermediate node during one of either a shared time slot or a dedicated time slot in response to at least one of the timing of dedicated time slots and data collision rates during shared time slots.

Abstract: A method of operating a network on a plurality of frequency hopping channels is disclosed. The method includes transmitting a beacon on a beacon channel different from the frequency hopping channels and receiving a request from a node to join the network in response to the beacon. The method further includes adding the node to the network in response to the step of receiving and communicating with the node on the plurality of frequency hopping channels after the step of adding.
