1. Delivery Traffic Indication Message

   Traffic indication map (TIM) is a structure used in 802.11 wireless network management frames. The Traffic indication map information element is covered under section 7.3.2.6 of 802.11-1999 standard.The IEEE 802.11 standards use a bitmap to indicate to any sleeping listening stations that the Access Point (AP) has buffered data waiting for it. Because stations should listen to at least one beacon during the listen interval, the AP periodically sends this bitmap in its beacons as an information element. The bit mask is called the Traffic Indication Map and consists of 2008 bits, each bit representing the Association ID (AID) of a station. However in most situations an AP only has data for a few stations, so only the portion of the bitmap representing those stations needs to be transmitted. Because the bitmap is never transmitted in its entirety, it is referred to as a virtual bitmap, and the portion that is actually transmitted is referred to as a partial virtual bitmap.

1. Delivery traffic indication message

   A delivery traffic indication message is a kind of traffic indication map which informs the clients about the presence of buffered multicast/broadcast data on the access point. It is generated within the periodic beacon at a frequency specified by the DTIM Interval. Beacons are packets sent by an access point to synchronize a wireless network. Normal TIMs that are present in every beacon are for signaling the presence of buffered unicast data. After a DTIM, the access point will send the multicasted/broadcasted data on the channel following the normal channel access rules. This helps to have minimum collision and in effect, increased throughput. In cases where there is not much interference, or where the number of clients is limited, the DTIM interval has little or no significance. Usually a value of 1 or 2. Also see Wi-Fi as established by the Wi-Fi Alliance According to the 802.11 standards, a Delivery Traffic Indication Message period value is a number that determines how often a beacon frame includes a Delivery Traffic Indication Message, and this number is included in each beacon frame. A DTIM is included in beacon frames, according to the DTIM period, to indicate to the client devices whether the access point has buffered broadcast and/or multicast data waiting for them. Following a beacon frame that includes a DTIM, the access point will release the buffered broadcast and/or multicast data, if any exists.
