Abstract: Systems and methods for distributed overlay multi-channel MAC for wireless ad hoc networks are described. In one aspect, the systems and methods divide channel frequencies defined by a wireless network protocol into a single home channel and multiple guest channels that are orthogonal to the home channel. Each of the network nodes in the ad hoc network operates on the home channel for respective variable and overlapping amounts of time to maintain network connectivity with other respective network nodes. Additionally, each of the network nodes determines whether and when to switch from the home channel to a particular guest channel of the guest channels for a variable amount of time to increase data throughput over one or more corresponding communication links in the ad hoc network with other network node(s).

Abstract: A switching power supply controller has a nominal loop gain and transient loop gain that is only activated in response to an abrupt load change in one direction. The transient loop gain may be implemented with a series-connected diode and resistor combination arranged in a feedback configuration with an error amplifier. A large load change in one direction may swing the output of the error amplifier and forward bias the diode to create a non-linear gain change.

Abstract: The present disclosure is related to a method for monitoring upstream burst performance in a point to multi-point access network. The method comprises: determining the expected time of the upstream data burst from the current terminal end (TE) reaching the head end (HE) using the timeslot assigned to the current TE, monitoring the actual time of the upstream data burst from the current TE reaching the HE, calculating and saving the difference between the expected time and the actual time of the upstream data burst from the current TE reaching the HE; calculating and outputting whether the difference is equal to or exceeds the TE's performance index value for the predetermined monitoring terms. The method provided by the present disclosure may monitor upstream burst performance of the entire network and discover the TEs with potential malfunctions, to effectively improve the network's stability.

Abstract: A method provides differentiated quality of service (QoS) by providing adaptive updates to media access control (MAC) layer parameters on a distributed basis. The method includes calculating a failure probability for a transmission over the network, determining a target value for determining a contention window according to a mapped function of the failure probability, and altering the contention window according to a scaling function of the target value. The mapped function and the scaling can provide QoS differentiation. A wireless device ensures fairness in a wireless time slotted network and includes a network interface card (NIC), a network driver interface, a network monitor, a statistics engine, and an adaptive parameter engine for determining a target value for determining a contention window according to a mapped function of the one or more probabilities to enable an alteration of the contention window and provide new parameters for the MAC layer.

Abstract: Techniques for synchronizing data signals and clock signals of a programmable logic device (PLD) are provided. In one example, a method includes preparing an initial configuration of the PLD identifying a plurality of data paths associated with the data signals and a plurality of clock paths associated with the clock signals. The method also includes identifying a hold time violation associated with at least one of the data paths, wherein at least one of the clock signals is used to synchronize the data path. The method further includes selectively adjusting a delay period of a delay element of at least one of the clock paths associated with the clock signal to attempt to correct the hold time violation without concurrently attempting to correct any setup time violation associated with the data path.
