Designing and Fine Tuning a Fire Safety Monitoring System for Smart Buildings using RPL Protocol

. Internet of Things is a well established technology for a wide variety of applications like Smart Homes, Smart Buildings, Healthcare, Agriculture, Aviation, AMI etc. Fire tragedy is one of the most damaging risk that could occur for an industrial, commercial or residential building. IoT can be successfully employed in large buildings to safeguard the occupants and also its infrastructure. To this end, a smart building is equipped with large number of economic sensors that forms an LLN (low power lossy network) with border router for Internet connectivity. RPL is a routing protocol for LLNs that ensures that tiny battery operated sensor devices could form a network with automated address configuration, spontaneous topology formation, IPv6 connectivity and fail-safe operation. This paper proposes an enhanced application of RPL protocol which increases the longevity of the portable nodes and assures quick response during a fire. This paper explains the required IoT infrastructure along with an application that provides a live web page with color codes to monitor the temperature of the different regions of a smart building.
