A real traffic replay over wireless networks with environment emulation and an event-driven automata-synchronized replay method are disclosed. The system includes a first traffic capture module configured to capture packet traces and environment effects in a real environment, a first event transform module configured to transform the packet traces into a sequence of events, and a reproduce module configured to receive the environment effects from the first traffic capture module and the sequence of events from the first event transform module such as to control a replay of the environment effects in the real environment and the sequence of events coordinately by means of automata.

System for real traffic replay over wireless networks

A frame-merging method is adapted for a network that includes mesh and terminal units, in which any two units capable of communication form a communication pair, and one of the units operates as a key unit to transmit pending frames according to the frame-merging method. The frame-merging method includes: determining whether the key unit is a mesh or a terminal unit; for the communication pair recorded in each pending frame, selecting a suitable scheme from a plurality of frame-merging schemes, and extracting at least one of the pending frames from among the pending frames for use as part or all of a priority frame set; and comparing a total size of all frames included in the priority frame set with a suitable frame size, so as to determine whether the key unit is to send an aggregated frame. A frame-merging apparatus is also disclosed.

Frame-merging apparatus and method

A channel utilizing method for a wireless network is adapted for channel utilization by a switch node having a number (N) of transceivers in an environment with a number (M) of channels, wherein (N)&#x3c;(M). The channel utilizing method includes the steps of: calculating a channel weight set, and selecting one of the (M) channels according to the channel weight set; determining a notify mechanism according to a relation between the switch node and a neighbor node; using the notify mechanism to notify the neighbor node of a current state of the switch node; and calculating a channel stay-in period, and causing the switch node to stay in the selected one of the channels for a duration of the channel stay-in period. A channel utilizing system is also disclosed.
