Ryan points out that new technologies – everything from vibrating mobile phones to laser light shows – enable us all to experience a collision of senses, leading to a kind of "cultural synaesthesia".
As employees increasingly interact with their professional contacts in online social networks that are personal in nature, such as Facebook or Twitter, they are likely to experience a collision of their professional and personal identities unique to this new and expanding social space.
A receiver within the interference range of multiple nodes, whilst trying to receive from one node, may experience a collision; as a result, all active nodes waste resources.
Because of that, in an environment with APs and clients transmitting on the same channel, there is a high probability of experiencing a collision if two simultaneously transmitted frames interfere at the receiver.
However, allocating different activity windows to the clusters means that, when a given node is transmitting, all members of every neighboring cluster have to be silent, and not only those that can experience a collision with the relevant transmitting node.
According to the decoupling assumption (2), the tagged node will experience a collision if at least one of the remaining n−1 nodes transmits, where n (n≥2) is the number of contending nodes.
While an atmospheric particle at sea level will travel a microscopic distance before colliding with another molecule, the thermosphere is so diffuse that a typical atom or molecule up there might travel for a kilometer or more before experiencing a collision.
The initial value of a device's contention window is C W min, and this value will be duplicated in case the device experiences a collision; otherwise, if a transmission is successful, the value will return to C W min. On the other hand, when the device's contention window reaches to C W max, the device has to sustain the value even if it encounters another collision.
