Drastic developments in the area of Wireless Sensor Networks (WSNs) have paved a path for ap-
plications in so called Internet of Things (IoT). Some major applications include remote health
monitoring, environment monitoring, smart grids etc. In this work we have identified the primary
issues that IoT architectures are facing and developed a system architecture to address the issues
identified. IoT architectures primarily face the power constraints due to their battery dependency in
remote deployment such as remote health monitoring. Other issue is the hyper connectivity scenario,
where the data generated by the sensor networks should have to be limited for efficient management
of networks. The proposed architecture consists of an intelligent data transmission mechanism with
smart sensing and IEEE 802.15.4 - PHY is considered for communication facility
