Abstract

A communication device includes a communication port including network interface circuitry; and a processor, and a non-transitory storage medium configured to store program instructions which, when executed by the processor cause the communication device to perform a network operation comprising: entering into a listening phase; and searching for and attempting to acquire a network.

Claims

1-23. -23. (canceled)

24. A communication device comprising:

at least one module operable to, at least;

select a number of beacon phase cycles, between a minimum number of beacon phase cycles and a maximum number of beacon phase cycles, to perform in a beacon phase;

operate in a listening phase in which the at least one module, at least, searches for a beacon on a plurality of channels of the network; and

if no beacon is heard during the listening phase, then operate in the beacon phase in which the at least one module, at least, transmits beacons over the network and listens for a transmission on the network by another communication device, wherein the beacon phase comprises the selected number of beacon phase cycles.

25. The communication device of claim 24, wherein the at least one module is operable to listen for a transmission on the network by another communication device by, at least in part, operating to:

listen for a response to beacons transmitted by the communication device; and

listen for beacons transmitted over the network.

26. The communication device of claim 24, wherein the at least one module is operable to select a second number of beacon phase cycles during a single network forming procedure.

27. The communication device of claim 24, wherein the at least one module is operable to select the number of beacon phase cycles randomly.

28. The communication device of claim 24 wherein the at least one module is operable to determine the maximum number of beacon phase cycles based, at least in part, on a last operating frequency of the communication device.

29. The communication device of claim 24, wherein the at least one module is operable to

select a duration of the listening phase between a minimum listening phase duration and a maximum listening phase duration;

and

operate in the listening phase for the selected duration of the listening phase.

30. The communication device of claim 29, wherein the at least one module is operable to select the duration of the listening phase randomly.

31. A communication device comprising:

at least one module operable to, at least;

select a listening phase duration between a minimum listening phase duration and a maximum listening phase duration;

operate in a listening phase for the selected duration, in which the at least one module, at least, searches for a beacon on a plurality of channels of the network; and

if no beacon is heard during the listening phase, then operate in a beacon phase in which the at least one module, at least, transmits beacons over the network and listens for a transmission on the network by another communication device.

32. The communication device of claim 31, wherein the at least one module is operable to listen for a transmission on the network by another communication device by, at least in part, operating to:

listen for a response to beacons transmitted by the communication device; and

listen for beacons transmitted over the network.

33. The communication device of claim 31, wherein the at least one module is operable to select a second listening phase duration during a single network forming, procedure.

34. The communication device of claim 31, wherein the at least one module is operable to select the listening phase duration randomly.

35. The communication device of claim 31, wherein the minimum listening phase duration is an amount of time required to search each channel of the plurality of channels at least once.

36. The communication device of claim 31, wherein the at least one module is operable to select a number of beacon phase cycles, between a minimum number of beacon phase cycles and a maximum number of beacon phase cycles, to perform in a beacon phase.

37. The communication device of claim 36, wherein the at least one module is operable to determine the maximum number of beacon phase cycles based, at least in part, on a last operating frequency of the communication device.

38. The communication device of claim 31, wherein the at least one module is operable to randomly select a number of beacon phase cycles to perform in the beacon phase.

39. A communication device comprising:

at least one module operable to, at least;

randomly select one or both of

a number of beacon phase cycles to perform in a beacon phase; and

/or

a duration in which to operate in a listening phase;

operate in the listening phase in which the at least one module, at least, searches for a beacon on as plurality of channels of the network; and

if no beacon is heard during the listening phase, then operate in the beacon phase in which the at, least one module, at least, transmits beacons over the network.

40. The communication device of claim 39, wherein the at least one module is operable to randomly select the number of beacon phase cycles between a minimum number of beacon phase cycles and a maximum number of beacon phase cycles.

41. The communication device of claim 40, wherein the at least one module is operable to determine the maximum number of beacon phase cycles based, at least in part, on a last operating frequency of the communication device.

42. The communication device of claim 39, wherein the at least one module is operable to randomly select the duration in which to operate in the listening phase between a minimum listening phase duration and a maximum listening phase duration.

43. The communication device of claim 42, wherein the minimum listening phase duration is an amount of time required to search each channel of the plurality of channels at least once.
