Abstract
This disclosure relates to wireless communication techniques. According to some embodiments, a wireless device may select a random number and sequentially advertise the bits of the random number. If the wireless device advertises the highest random number, it may proceed to transmit a packet using a channel. If another device advertises a higher number, the wireless device may not transmit its packet and may restart the process.
Claims20
A wireless device, comprising:
- a radio;
- and
- a processing element;
- wherein the radio and the processing element are configured to contend for access to a medium, said contention comprising:
- selecting a random number comprising N bits;
- sequentially, for each of at least a subset of the N bits:
- transmitting, when the bit is equal to a first value, the bit on the medium and transitioning to the next bit;
- and
- determining, when the bit is not equal to the first value, if another device transmits a bit on the medium, and:
- when at least one other device transmits a bit, restarting the contention;
- and
- when no other device transmits a bit, transitioning to the next bit;
- and
- transmitting at least one packet on the wireless network.
11 more elements
A method for contending for access to a wireless network by a wireless device, the method comprising:
- generating a random number comprising N bits;
- sequentially transmitting respective bits of the random number onto a channel of the wireless network over respective time slots;
- comparing the random number to a random number of any other wireless device contending for access to the wireless network;
- and
- based on the comparison, determining whether to gain access to the wireless network.
2 more elements
An apparatus, comprising:
- one or more processing elements, wherein the one or more processing elements are configured to cause a wireless device to:
- select a random number;
- sequentially advertise bits of the random number, wherein said sequentially advertising a bit comprises determining whether to proceed to a next bit based at least in part on the value of the bit;
- and
- after sequentially advertising a last bit of the random number, access the wireless network.
