What is Smart Lighting

System Architecture and Networking

PAGE 2 6/30/2010

  • A smart lighting system composed of two or more

heterogeneous networks based on different platforms is called a Heterogeneous Smart Lighting System (HSLS).

  • A smart lighting system refers to a system where multiple

luminaries with actuators and light sensors are connected in a network, and cooperate to meet the requirements of users.

Background

  • Approaches to IP integration of WSNs so far:

Pure TCP/IP solutions: sensor nodes implement the TCP/IP stack (or a compatible set

  • f protocols such as 6LoWPAN in 802.15.4 networks); and

Gateway solutions:

System Architecture and Networking

PAGE 3 6/30/2010

  • One node acts as an application layer gateway (e.g. base

station), to make the lower layer protocols from both networks (e.g. TCP/IP, IEEE 802.15.4) transparent and to route information.

  • Sensor nodes implement the TCP/IP stack (or a compatible

protocols such as 6LoWPAN in 802.15.4 networks)

OSAS

  • Open Service Architecture for Sensors is an integrated

environment for programming wireless senor networks.

  • OSAS toolchain

− Development

− Simulator (for functionality) − Compiler − Loader

− On-node

− Interpreter

  • OSAS software components:

− Services: functionalities − Subscriptions: requests for using services − Content based addresses

Conclusions

  • Proposed a heterogeneous smart lighting system

approach for distributed LED luminary control and an light model based on user preferences.

  • The light model guarantees that the desired

illumination levels of user preferences are achieved.

  • Interoperability between low and high capacity nodes

from OSAS and Smart-M3 platforms, respectively.
