Using this methodology, a
wireless network can be self-forming or “ad-hoc” in nature. That is, the formation of the network does not depend upon the presence of a pre-determined central coordinator. Second, it can accommodate relatively rapid changes in
network configuration, including changes in the number and location of the devices participating in the network, and changes in the channel conditions experienced by communication devices. Third, it can accommodate an extended network
system where the
population of devices that are able to communicate wirelessly, either directly, or indirectly via devices that also act as repeaters, may be spread over a relatively large
geographic area. Fourth, it can provide robust
Quality of Service through the
use of time reservations or “slots” during which one device or a limited number of devices are allowed to transmit. Fifth, it can provide good
power management qualities, such that there are mechanisms which allow devices minimize
active time and to transition in and out of reduced power “sleep” states while still maintaining the ability to communication.
