FIRMWARE COMPRESSION MECHANISM FOR SPEEDING UP FIRMWARE UPDATING IN A RESOURCE RESTRICTED NETWORK

Techniques are described herein for adopting a substring list creation and extraction mechanism as well as a variable-length patch mechanism to generate an Over-The-Air (OTA) image path file having a small size. This saves network resources and reduces side effects on data transmission / network service when executing image / firmware upgrading. As a result, OTA updating can be sped up, and the peak network traffic during the firmware updating may be narrowed

OPTIMIZING UPWARD LOAD BALANCING FOR LOSSY AND LOW-POWER NETWORKS

Presented herein are techniques for better load balancing of uplink flows at an overloaded node. The techniques presented herein leverage the capacity of neighboring nodes in order to share the traffic from the overloaded node. As a result, after several rounds of sharing, the probability of congestion decreases exponentially

A NOVEL TECHNIQUE TO PERFORM LARGE FILE UPDATES ON INTERNET OF THINGS (IOT) DEVICES USING BLOCK CHAIN IN LOW-POWER AND LOSSY NETWORKS (LLNS)

Proposed herein is an efficient large file update (e.g., a firmware update) technique that utilizes blockchain technology, rather than a classic centralized solution. This technique adopts a decentralized and distributed architecture to disseminate information, which may greatly reduce bandwidth occupation and accelerate the updating process. Various benefits may also be realized by this technique including, but not limited to: 1) making sure that each piece of a block is correct through a blockchain hash (e.g., a node could be aware of the legality of a file download before the whole file download is completed); 2) as opposed to a Multicast Protocol for Low-Power and Lossy Network (MPL) solution, all nodes do not need to conserve as many packets as possible in Random Access Memory (RAM), rather a block may be saved directly into non-volatile flash, which could mitigate the usage pressure for temporary buffers; and/or 3) as opposed to a centralized solution, this technique does not need to exchange information with a Network Management System (NMS), rather a node may pull missing blocks from its neighbors as long as they have them and, after two rounds of failures, it can turn to the NMS, which may not result in concurrent traffic to the NMS

IMPROVING NETWORK THROUGHPUT OF CONNECTED GRID ROUTER WIRELESS PERSONAL AREA NETWORK FOR MASTER AND SLAVE CASE

Techniques are described herein to cause a Master and Slave Wireless Personal Area Network (WPAN) to share the same 64-bit Extended Unique Identifier (EUI64) address. In response, the first hop dual-phy node transmits most of the upward data flow to the router via the Radio Frequency (RF) link, and the router transmits most downward data flow via the RF link. Because the RF link has much more bandwidth than the Power Line Communication (PLC) link, this mechanism takes full advantage of network resources and extends the network throughput

DIGITAL ADDRESSABLE LIGHTING INTERFACE PROTOCOL OVER WIRELESS MESH NETWORK

Techniques are described herein for applying Digital Addressable Lighting Interface (DALI) protocol in existing Wireless Mesh Networks (WMNs). The DALI-based lighting market has experienced a large growth in recent years because of the potential for intelligent lighting systems to cut down many costs of initial investment, energy, and maintenance. However, traditional control systems cannot not meet large-scale Light Emitting Diode (LED) deployments in practice. DALI protocol may provide more stable connectivity among nodes, reduce redundant traffic, and transmitting broadcast commands with high efficiency

CROSS PERSONAL AREA NETWORK COMMUNICATION BY CONNECTED GRID MESH NETWORK IN LIGHTING AREA

Techniques are described herein for broadcast and unicast mechanisms to perform cross Personal Area Network (PAN) communication in a Connected Grid Mesh (CG-Mesh). Neighboring PAN information (e.g., security, PAN, etc.) is stored in a cross-PAN node. A lighting group Identifier (ID) allocation may be used for the broadcast mechanism, and route table creation may be used for the unicast mechanism. This allows a system to meet any lighting timing requirements

RANDOM FORESTS BASED ON DYNAMIC NETWORK PARAMETERS IN LOW POWER AND LOSSY NETWORKS

Techniques are described herein for a random forest - based mechanism to select network parameters in Low-power and Lossy Networks (LLNs). These techniques may simplify configuration, accelerate network formation and network convergency, and reduce collisions
