Custom Network Protocols for Secure Wireless-to-TCP/IP Communications
The U.S. Navy developed custom network protocols that enable low cost, low power security monitoring of global shipping containers.
In order to improve global cargo container security, SSC Pacific developed custom network protocols, Fixed Network Access Devices, and Handheld Network Access Devices which included an Android-based mobile app. These technologies allow for monitoring and control of IEEE 802.15.4-based electronic locks and security devices on shipping containers throughout the global supply chain. The custom network protocols are described below.
SSC Pacific’s custom network protocols are a set of air interface discovery, data format, and messaging procedures that provide secure wireless-to-TCP/IP communications among a global ad-hoc network of container security devices, Network Access Devices (NADs), and Data Centers. Using the protocols, a conveyance-mounted security device conducts network discovery to communicate with a NAD via IEEE 802.15.4. The security device provides uniquely formatted data to the NAD, which in turn relays the data to a Data Center via TCP/IP. The protocols enable status updates to be sent from security devices to Data Centers, and commands, such as arm and disarm, between Data Centers and security devices.
