7.1 Introduction
This chapter discusses the critical technologies that are used in the development
of optical wireless communication network, for the provision of safety
and convenience to the vision-impaired population. The technologies of
the hardware, firmware, decision algorithms, communication protocols,
and application programs developed for sensor nodes in optical wireless
communication network are applied for the smart blind-guidance network
system. It follows the latest specifications, concepts, and trends in the
design of sensor nodes to meet its requirements for applying in the nextgeneration
wireless network. In addition, this technology is supplemented
by the assistant equipment (cane) for the blind and the communication
