Abstract: A wireless mesh network includes a controller in wireless communication with a plurality of slave devices where each slave device is assigned a virtual routing number that defines a time slot in a TDMA communications frame. The slave devices are configured to receive, out of band and/or separately from the TDMA communications frame, asynchronous transmissions of sensor data from battery operated sensor devices. The battery operated sensor devices transmit asynchronously and do not participate in the TDMA communications frame in order to save battery power. The slave devices store data received from the sensor devices until the data is requested by the controller through an initiation message. In response, the slave devices aggregate data received directly from asynchronous communications with data received from other slave devices during an accumulation process that passes the accumulated date back to the controller through the mesh network during a TDMA acknowledgement frame.

Abstract: Techniques for data compression for efficient network management are described herein. In one example, group(s) of bytes are formed from among input bytes to be compressed. The groups are formed by including bytes having at least a certain number (e.g., three) zero-valued most significant bits (MSBs). A byte of input data having several zero-valued MSBs may be in several groups. A group having the largest product (number of bytes in the group times number of zero-valued MSBs in all bytes in the group) may be selected. A compressed-bytes array may be formed with data of the selected group of bytes, wherein the number of zero-valued MSBs originally present in all of the bytes of the group of bytes has been removed (to compress the array). An uncompressed-bytes array may be formed with bytes of the input bytes of data not in the selected group of bytes. An address-bit array may be formed to indicate the array in which data associated with each of the input bytes of data is stored.
