What is DSA (Dynamic Service Addition)?

By utilizing a three-way handshake protocol alluded to as Dynamic Service Addition (DSA), in WiMAX, portable networks associations, also alluded to as service flows, can be dynamically activated between the base station and the versatile stations. Blocking probability, admission control probability, and latency of DSA protocol are assessed, for various conditions of portability and parameters of PHY and MAC layers. In any case, degraded channel quality and questionable message retransmissions might lead to an unsuccessful activation of a service flow.
