Abstract: A system and method for controlling dynamic transmit power in a mesh network are disclosed. Distributed power transmit management methodology that implements transmission power management based on a comparison of signal to noise ratios from received beacon packets is used on a peer-to-peer basis. Embodiments work to keep all nodes accessible, dynamically adaptable to constant changes in the network, maximize frequency reuse, and reduce power requirements to maximize network performance while minimizing interference.

Abstract: The disclosure is generally directed to a method and apparatus for encrypting and decrypting data on an integrated circuit. In various implementations, the apparatus includes an on-chip high performance bus bridge that transparently encrypts and decrypts data between the embedded microprocessor(s) and off-chip system memory. In some implementations, the apparatus is optimized to the transactions generated by the processor's cache controller (e.g., optimized for cache line size) and optimized to the bus protocol being used. This provides code protection with minimal effect on system performance latency and throughput. The implementation of multiple cryptographic engines allows for encryption of a complete cache line while incurring only a single latency for the first cipher rounds to be completed.

Abstract: Systems, devices, and methodology for removing echo and reducing congestion in multicast (broadcast) over a dynamic self-healing mobile mesh network, by use of discrete embedded computers synchronously tracking mesh connections and link quality across multiple RF connections, keeping multicast both efficient and effective in a highly kinetic, ever changing, mesh topology.

Abstract: A system and method to mitigate or complicate the use of differential power analysis (DPA) and simple power analysis (SPA) in the attack of a targeted integrated circuit, or device containing an integrated circuit, that is processing sensitive information. The system and method modifies the regularity of a clock that initiates the power events within the circuit such that subsequent processing of information does not always occur at the same time.

Abstract: Computer networks with multiple nodes are often required to deliver packets to all nodes in the network, commonly referred to as “flooding.” Flooding is used to deliver multicast and broadcast packets generated by application, network and other layers of the networking stack. Flooding can be done very reliably but less efficiently via node to node “unicast” transmissions, or very efficiently but less reliably via “broadcast” transmissions. In order to balance reliability with efficiency, this invention defines a threshold for the number of neighboring nodes as seen by a given node prior to a flooding operation to determine whether data should be unicast or broadcast. Below that threshold, unicast is used; at or above that threshold, broadcast is used. The invention also incorporates knowledge of nodes seen in turn by neighbor nodes as part of this decision.

Abstract: Networks based on Internet Protocol (IPv4) employ an administrative Address Resolution Protocol (ARP) to convert logical IP addresses into physical Ethernet media access control (MAC) addresses. These queries address the entire network, and in very large networks, they contribute substantially to network traffic. This invention identifies ARP packets in a large, dynamic network and uses various means to minimize their broadcast throughout the network. This results in optimized network performance.

Abstract: Traditional computer networks have been designed with the need for highly reliable packet delivery. This is largely handled by a centrally managed simple send-acknowledge protocol. In a highly dynamic mesh network, these methods are inadequate to ensure the most reliable packet delivery. This invention uses the natural redundancy of routes in a mesh and other techniques to increase the reliability of a network, even as the paths to any given node are dynamic in nature.

Abstract: The protocol determines the quality of each node to node link(s), based on an exponentially weighted moving average of the time each packet spends within the network node. Once determined, that quality of link is then mapped into the physical QoS resources of the networking hardware in use (within the network). Packets destined for higher quality links will see an upgrade of their QoS rating, while packets destined to lower quality links will see a downgrade of their QoS rating. That adjustment permits the higher quality links to be processed before the lower quality links resulting in more efficient and complete communications in the network. Poorer quality links will no longer act as roadblocks to the higher quality packets.
