摘要： A buffer management scheme for an ATM switch where the static and dynamic thresholds are applied appropriately at different levels to ensure efficient and fair usage of buffer memory. A novel dynamic threshold mechanism which, while ensuring fair sharing of memory, maximizes the overall memory utilization. An ATM switch using a dynamic queue threshold scheme, said ATM switch comprising K output port queues and a buffer of B cells sharing said K output port queues, wherein a common threshold is dynamically set for the K output port queues, the common threshold being changed to a new value from an old value when a new cell arrives at any of said K output queues, said new value being a maximum of a length of said any of said K output queues plus one and said old value when total queue length is less than a preset value times B and, said new value being a maximum of a said old value minus one and a statically set minimum buffer threshold when total queue length is greater than or equal to a preset value times B, wherein said preset value is greater than or equal to 0.

摘要： An ad-hoc network and routing method that takes account of mobility are provided. The ad-hoc network includes at least one node, which calculates a probability that a neighbor node is present in a transmission range of the node, generates a message containing the calculated probability, and transmits the message to the neighbor node. The at least one node may also update the message with a lower probability of the calculated probability and a probability contained in the message, and transmit the updated message to the neighbor node. The node may also determine as a route a path along which a message is transmitted from the message containing the highest probability among probabilities contained in messages that are received.

摘要： Embodiments of the present invention provide a method for tracking link mobility between two mobile nodes. Each node estimates a link mobility state of a link between itself and each of its neighbor nodes, accumulates successively the link mobility states, estimates link mobility parameters using the successively estimated link mobility states, and predicts a link availability probability using the link mobility parameters. The link mobility tracking can be applied to various routing protocols so as to implement mobility aware routing which enhance the routing performance.
