Abstract: A network has wireless enabled nodes of more than one hardware type. A computing device obtains a software update for one of the node types and sends an announcement of availability through the network. The announcement includes a node type identifier. A node that recognizes the identifier as matching its own hardware type collects the software update through a series of one or more requested packet transfers from the controller. Each packet carrying part of the update also includes the node type identifier. A node of a different type that has received the packets may serve as a source of missing packets to other nodes. Alternatively, nodes needing missing packets can fetch them from the computing device. When the software update is completely received by a node of the identified type, that node reboots and executes the updated software. Any node of another type discards the packets.

Abstract: Disclosed are examples of a method, system and asset tag that enables general, coarse and fine estimates of a location of the asset tag. The asset tag receives a signal transmitted from radio frequency (RF)-enabled nodes within a space. Each respective received signal includes a unique node identifier of the respective RF node that transmitted the respective received radio signal. Each RF node has a physical node location in the space that is associated with the unique node identifier. The tag measures the received signal strength of each respective received signal that is associated with the node identifier of the RF node that transmitted the respective received signal. The strongest measured received signal strengths are selected, and a tuple containing the node identifiers for the selected strongest signal strengths is forwarded for estimating a location of the asset tag by a computing device.
