Abstract: The present invention comprises methods and systems of a network of sensor devices to monitor environmental conditions. Each sensor device is capable of acquiring environmental data and transmitting the data to a central controller of a networking system by wireless communication. By processing the environmental data obtained from the geographically deployed sensor devices, the central controller is capable of detecting a trend of the hazardous condition. The central controller generates early warning signals based on the hazardous levels of the physical or environmental conditions, as well as the trend of such conditions. When receiving a high level of hazardous conditions from one of the networked sensor devices, the central controller can compare the results with neighboring sensor devices to determine whether the signal received is due to a hazard leakage or a sensor device malfunction, so to reduce false alarms and provide feedbacks to communication devices networked in the system.

Abstract: Systems, methods, and devices for acknowledging communications from a plurality of wireless devices in a wireless network are described herein. In some embodiments, an access point for the wireless network transmits a group acknowledgment (ACK) to indicate whether communications (packets) from the plurality of wireless devices have been received or correctly decoded within some time interval. Each wireless device may have a different time interval associated with it. For some embodiments, the time interval for a wireless device is relative to when a previous group ACK was sent. A group ACK may include a bitmap. In some embodiments, the bitmap indicating whether a communication has been received or correctly decoded may be transmitted as part of a beacon.

Abstract: A method includes creating a plurality of data fragments from a single data unit. The method also includes transmitting the plurality of data fragments to a receiver and receiving an acknowledgement from the receiver after transmitting a last data fragment of the plurality of data fragments. The method further includes selectively interpreting the acknowledgement as a multi-fragment acknowledgement (MFA) in response to a value of a fragment sequence number (FGSN) of the last data fragment. The MFA indicates receipt or non-receipt by the receiver of each of the plurality of data fragments of the single data unit.
