Abstract: Low-powered wireless communication devices are used for control and monitoring in a wide range of applications, including, but not limited to, home automation, agriculture, energy management, infrastructure monitoring, and defense systems. RPL (Routing Protocol for Low Power Lossy Networks) is used for networking between routers and their interconnections in wireless communication environments that are characterized by high loss rates, low data rates, and instability. The present invention improves the performance of RPL by adding a weighted average Link Quality Indicator to a Rank determination methodology for selecting parent nodes in establishing and maintaining an RPL network.

Abstract: A wireless sensor network is disclosed. A content management system (CMS) communicates with a gateway over a network connection. The CMS operates with a registration service operating on a computer or mobile device. Under the control of the registration service the gateway may be registered on the WSN. Nodes seeking to register to the WSN must satisfy a two level validation process. A first level of validation involves comparing a network identifier and a media access control (MAC) key with values established during a factory setup of the node. A second level of validation involves a comparison of a MAC address of the node with a whitelist of authorized nodes stored in the gateway.
