Abstract: Different real-time applications have different requirements in Wireless Sensor Network (WSN). Some may be time critical (hard) some may have soft deadline some need huge amount of data to be transmitted but subjected to bandwidth constraint and others may be low data rate and battery constrained. Design of hardware and software is crucial to address these requirements. Numerous routing protocols proposed in literature restricts to only simulation and only few are implemented and tested in sensor-mote based hardware platform(s). This work focuses on scalable hierarchical tree based real time cross layered routing protocol for Internet of Things (IoT) based static multi-hop wireless sensor network. The objective function for parent selection and association for next hop forwarding is based on link quality metric (LQI) estimated by the IEEE 802.15.4 radio transceiver based on Received Signal Strength Indicator (RSSI). The tree formation process avoids implosion problem by incorporating sleep schedule to achieve energy savings and optimal transmission power level selection. The implementation is experimented in test-bed in a linear chain deployment using SENSEnuts stack sensor mote hardware platform. Also, simulation results in Ns2 is modelled with a realistic log-normal shadowing and performance metrics are analyzed for linear chain of nodes.
