Claims4
For a network of stations having a Base Station, wherein each station sends messages to the Base Station and the sending of a message requires power, and each station is provided with power and each station has a clock and persistent memory and wherein the Base Station maintains a network time for the network stations to coordinate with, a method of recovering the state of the network stations upon the occurrence of a disturbance of that power and a resumption after the power disturbance, comprising the steps of:
- each station, while powered,
- (a) keeps in said memory, a copy of each message after said message is sent;
- (b) indicates on said message copy the status as said message is being sent;
- (c) stores time-stamps, based on each station's clock, with each said message copy indicating a time of sending;
- (d) upon the occurrence of the power disturbance and then the power resumption, sending to the Base Station, each said time-stamped message copies;
- and the Base Station re-assembling the messages in chronological order based on said message copies;
- and wherein said clock re-starts at the time said clock had upon the power disturbance and continues until said clock is able to be coordinated with the network time.
