Adaptive
Traffic Balancing
•The number of collisions that can be seen by a node over a certain period can indicate the node mobility or medium usage condition more precisely than other parameters
-The faster nodes move, the larger number
of collisions can be observed by nodes
-The larger number of collision happens,
the more backoff periods are and
less medium usage is detected
•Method
-Nodes measure the medium usage and number
of collisions over a certain period
-Based on the number of collisions, a suitable threshold is set
