Abstract
An asset tracking system that utilizes a wireless network system and which includes primary (active) and secondary (passive) tracking devices. The primary tracking device acts as a coordinator and the secondary devices surrounding the coordinator act as end-devices. Each secondary device can communicate only with the primary device. The primary device passes messages (data) from the secondary devices to the remote host transparently. Each secondary device only sends its data when it triggered by a 'ping' from the primary device. When a ping event occurs, the primary device broadcasts a main data packet, in some embodiments followed by two additional data packets. Within this time span of the primary data packet, the secondary devices send their data packets to the primary device, in some embodiments, as two small data packets.
