Ad-hoc network and method of routing communications in a communication network
First Claim
1. An ad-hoc network comprising:
- an ad-hoc network coordinator comprising;
a first processor, a first memory, and a first communication interface; and
a plurality of ad-hoc network devices, each of said ad-hoc network devices comprising;
a second processor, a second memory, and a second communication interface for communication with the first communication interface of said ad-hoc network coordinator or with the second communication interface of another one of said ad-hoc network devices, wherein said first memory stores for at least some of said ad-hoc network devices a complete communication route for messages from said ad-hoc network coordinator through at least one of said ad-hoc network devices to a corresponding one of said at least some of said ad-hoc network devices, and wherein said second memory of each of said ad-hoc network devices stores an identification of another one of said ad-hoc network devices to forward a message from the second communication interface of a corresponding one of said ad-hoc network devices toward the first communication interface of said ad-hoc network coordinator and through the second communication interface of said another one of said ad-hoc network devices.

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.

16. A method of routing communications in an ad-hoc network, said method comprising:
-
employing an ad-hoc network coordinator including a first communication interface;
employing a plurality of ad-hoc network devices;
employing with each of said ad-hoc network devices a second communication interface for communication with the first communication interface of said ad-hoc network coordinator or with the second communication interface of another one of said ad-hoc network devices;
storing a plurality of complete communication routes for at least some of said ad-hoc network devices for messages from said ad-hoc network coordinator through at least one of said ad-hoc network devices to a corresponding one of said at least some of said ad-hoc network devices; and
for each of said ad-hoc network devices, storing an identification of another one of said ad-hoc network devices to forward a message from the second communication interface of a corresponding one of said ad-hoc network devices toward the first communication interface of said ad-hoc network coordinator and through the second communication interface of said another one of said ad-hoc network devices. - View Dependent Claims (17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39, 40)
