Coordination between simultaneously operating Pico-Nets in high mobility wireless networks
First Claim
1. A dynamic wireless network comprising:
- multiple wireless sub networks operating within the range of each other, wherein each of said wireless sub networks is managed by a PNC, and wherein the transmissions of information within said sub network are synchronized by a beacon transmission from said PNC, and wherein PNCs adjust the timing of their beacon transmissions so as not to interfere with other PNC beacon transmissions.

Abstract
An embodiment of the present invention addresses Beacon Synchronization issues related to multiple Simultaneously operating Pico-Nets that could be potentially interfering with each other'"'"'s transmissions. Algorithms and support functions are described that determine the optimal staggering of Beacons in the Contention Access Period (CAP) of an IEEE 802.15.X Pico-Net, where 802.15.X denotes both 802.15.3 and 802.15.4 application sets. The objectives of this invention are related to both types of networks. The approach described is stable, scalable and efficient. It is comprehensive, in that it addresses all typical use cases for how Devices and Pico Net Controllers would need to coordinate beacon information to ensure trouble free operation.
