Abstract: In one aspect of the present invention, a method for managing communications in a sensor network will be described. A coordinator device receives charging interval data from an energy harvesting sensor device. A sleeping interval for the sensor device is determined. A beacon frame is transmitted from the coordinator device to one more sensor devices in a network. The timing of the transmission is based at least in part on the sleeping interval data. The beacon frame may contain requests, commands or other data designated specifically for the sensor device. Various other aspects of the invention relate to the sensor device, the coordinator device and/or their operations.

Abstract: Wireless communication in a wireless system using a multiple user transmission opportunity is provided. Data blocks at a wireless station are transmitted to multiple wireless receivers over a shared wireless communication medium. The data blocks are organized in order of transmission priority based on access categories. Contention for access to the communication medium during a transmission opportunity period is based on a backoff timer of each access category and the transmission priority. Upon successful contention for a transmission opportunity period, during the transmission opportunity period, a data block of a primary access category is wirelessly transmitted from the wireless station to one or more primary destination wireless receivers. Simultaneously, a data block of a secondary access category is wirelessly transmitted from the wireless station to one or more secondary destination wireless receivers.

Contending for the transmission opportunity period includes each access category contending for access to the wireless communication medium and a secondary access category selectively invoking communication medium access backoff based on one or more backoff events.
