Abstract
An ad-hoc low rate-wireless personal area network (LR-WPAN) includes an ad-hoc network coordinator having a first processor, a first memory, and a first communication interface; and a plurality of ad-hoc network devices. Each of the devices includes a second processor, a second memory, and a second communication interface for communication with the first communication interface of the coordinator or with the second communication interface of another one of the devices. A simple, low-cost, incremental source routing is employed. The first memory stores complete communication routes for messages from the coordinator through at least one of the devices to other devices. The second memory of each of the devices stores an identification of another device to forward a message from the second communication interface of a corresponding one of the devices toward the coordinator's first communication interface and through the second communication interface of that other device.
