    Abstract: A network system comprising a first network element and a second network element. The first network element is programmed to provide the step of first, communicating to the second network element a plurality of configuration parameter sets. Each configuration parameter set corresponds to a respective frame fragment and comprises a parameter value that differs in value from the parameter value in another configuration parameter set in the plurality of configuration parameter sets. The first network element also is programmed to provide the step of second, communicating a frame, to the second network element, in a plurality of frame fragments, wherein each frame fragment in the plurality of frame fragments is communicated according to a respective parameter value in the plurality of configuration parameter sets.

    Abstract: A BLE-Mesh device includes a controller, an RF driver for driving the transceiver adapted to be coupled to an antenna, and a counter. The controller implements an applications layer including BLE and Mesh Applications, and a BLE stack and a mesh stack. A redundant traffic suppression relaying algorithm is for waiting for a random time within a selected time window from W1 to a later W2 before attempting to transmit a first packet that contains a unique source (SRC) address and a packet sequence (SEQ) number of a device that is the source of the first packet. If during the random time a packet with both the source device's SRC address and the SEQ number is received, the counter is incremented from an initial count to a current count. After the random time elapses, the current count is compared to a Cthreshold value, and the first packet is transmitted only if the current count

    Abstract: Embodiments of the invention provide a method for performing network resource allocation over hybrid networks so that application QoS requirements are met. The hybrid networks are represented as an undirected weighted graph with the communication links as edges irrespective of the communication medium. A QoS-based resource allocation model. Another embodiment further includes utility functions that capture the QoS attributes such as reliability, timeliness, fault-tolerance and lifetime allows determining routes and bandwidth allocation such that the total system utility across the entire network is maximized.
