Systems and methods for collision management in a neighborhood aware network
Methods, devices, and computer program products for collision management of wireless devices in a peer-to-peer network are described herein. In one aspect, a method of communicating via a wireless medium by a wireless communications apparatus within a network is provided. The method includes determining first and second contention windows. The first contention window begins earlier than the second contention window. The method further includes beginning a first carrier sense multiple access (CSMA) countdown at the start of the first contention window. The method further includes beginning a second CSMA countdown when the first CSMA countdown does not end before the start of the second contention window. The method further includes transmitting the prepared frame at a time of the first CSMA countdown ending or the second CSMA countdown ending, whichever is earlier.
