H04W 52/02
H04W 56/00

Abstract:

A system including a plurality of network devices including one or more worker monitoring devices and one or more area monitoring devices is provided. The plurality of network devices monitor at least one of a peer alarm, a worker biometric datum or an area environmental datum. The plurality of network devices are structured to communicate with one another in an ad-hoc wireless mesh network. A first network device of the plurality of network devices transmits the at least one peer alarm, worker biometric datum or area environmental datum for presentation on a second network device of the plurality of network devices.

Abstract:

A wireless mesh network including a leader node and a plurality of follower nodes is provided. The leader node transmits a sync message to the plurality of follower nodes indicating a beginning of a network interval. The leader node and the plurality of follower nodes transmit information during a transmission period of the network interval and do not transmit information during a sleep period of the network interval. The leader node and the plurality of follower nodes use less power in the sleep period than in the transmission period; and the plurality of follower nodes each include a timer adapted to time the transmission period and the sleep period for each of a plurality of future network intervals in an absence of continued receipt of the sync message from the leader node during the plurality of future network intervals.

Abstract:

A network for connecting a plurality of network nodes including a leader node and a plurality of follower nodes is provided. The leader node transmits a sync message to the plurality of follower nodes indicating a beginning of a network interval. The sync message contains data indicating a number of network nodes in the network. The leader node and the plurality of follower nodes transmit information during a transmission period of the network interval and do not transmit information during a sleep period of the network interval. The network interval is of a fixed length of time, the transmission period is of a variable length of time based upon the number of network nodes in the network, and the sleep period includes remaining time of the network interval after the transmission period.

Abstract:

A network for connecting a plurality of network nodes includes a leader node and a plurality of follower nodes. The leader node transmits a sync message to the plurality of follower nodes indicating a beginning of a network interval, wherein the leader node and the plurality of follower nodes transmit information during a transmission period and do not transmit information during a sleep period of the network interval, and wherein during a predetermined time of the transmission period of the network interval each of the follower nodes that received the sync message transmit a message advertising one or more properties of the leader node. The network nodes are environmental sensing devices that are part of a worker safety system.
