Sorting packet mode by collisioning[edit]

Collision recovery:= methods that do not attempt to avoid collisions, merely detect and recover.

Collision avoidance:= methods that actively try to avoid collisions.

Collision free:= methods where collisions are impossible

If you can think of a better way to split up packet mode access methods, feel free to discuss.Mojodaddy (talk) 20:23, 12 February 2009 (UTC)[reply]

I think we should split collision avoidance with collision detection. --Schwal (talk) 00:54, 15 February 2009 (UTC)[reply]

Whats the advantage with this way of dividing the channel access schemes, as opposed to how it is done in the list of schemes in the channel access article?

I think it is important to find some references presenting how the schemes are divided in the literature.Mange01 (talk) 23:44, 15 February 2009 (UTC)[reply]

Split or combine, Schwal? Also, the division on the channel access page doesn't really make sense. A packet channel access method can either have collisions or it can't. So if contention is the underlying criteria for subdivision, then the methods should be broken up into contention based or non-contention based (where contention based can be further broken into collision avoidance versus collision detection). Furthermore, the "token passing" and "polling" sections don't really have room for expansion or particularly make sense. How does polling equate to a channel access method? Tokens are a general shared resource concept that can/were applied to transmission mediums. I don't see much expansion in this area as the only stuff out there are proprietary implementations of token rings (for instance, the token bus). I'm also confused about the resource reservation section. If it's a true resource reservation, then it's a circuit based communication, for example: selecting only assigned time slots in TDMA. If it's not a true resource reservation, then it's a contention based communication, for example: selecting random time slots in TDMA.Mojodaddy (talk) 22:01, 23 February 2009 (UTC)[reply]

PCF in collision avoidance[edit]

In Point Coordination function (PCF) access point controls the transmission and hence no collision in the network. In the template PCF is categorized under collision avoidance. I suggest to move PCF to collision free section. Does it make sense? any other suggestion or comments?
