Abstract:
1. A method of wireless medium access for establishing a decentralized wireless network, the method comprising: broadcasting of beacon frames by each of a plurality of devices; listening, at each device, for beacon frames of other devices; identifying, at each device, other devices whose beacon frames have been heard; and forming the decentralized wireless network functioning without a central controller, the decentralized wireless network in the form of at least two dynamic networks, each dynamic network being centered around one of the devices and having said other devices whose beacon frames have been heard by said one device as network members; and wherein at least one of the network members is in communication range of the at least two dynamic networks; wherein the beacon frame of each device comprises synchronization information, the synchronization information comprises scheduled next beacon frame broadcast time information of said each device and scheduled next beacon frame broadcast time information of other devices whose beacon frames have been heard by said each device; and wherein the broadcast of each beacon frame at the scheduled broadcast time by each device is subjected to a random delay such that, for each device, every pair of consecutive broadcast periods vary from each other, wherein said broadcast period is a period between consecutive beacon frames broadcasted by the device.
