Abstract: In a wireless mesh network having multiple network managers, the network managers maintain network security through the use of encryption keys and packet counters. To ensure that each network manager can authenticate communications with any node of the network, the authentication data is replicated in a disjoint manner in all network managers. Advantageously, network reliability is assured by providing redundant managers that can seamlessly maintain network operation even if multiple network managers fail; newly joining managers can obtain full authentication data for the network upon joining; and network throughput is increased by ensuring that any of the multiple managers can authenticate the communications of any network node. The disjoint replication of the authentication data across all network managers is performed with low data-rate manager-to-manager packets propagated through the network. The disjoint security methods and systems can advantageously be used in wireless battery monitoring systems, for example.

Abstract: In a wireless mesh network having a known or predetermined physical topology, a network node or access point (AP) may promptly begin operation on the network in response to receiving a network advertisement. In particular, the node or AP can store a network communication schedule and adjust the network communication schedule based on parameter value(s) received in the network advertisement received from the network manager. As a result, the node or AP can begin operating in accordance with a network's communication schedule promptly after receiving the network advertisement by transmitting packets using pairs of communication channels and timeslots assigned thereto in the adjusted communication schedule. The network communication schedule stored by the node or AP can take the form of an algorithm that takes the parameter value(s) received in the network advertisement as input(s) and, when executed by the node or AP, outputs the appropriate adjusted network communication schedule.
