The areas of WSNs (Wireless Sensor Networks) and Internet of Things (IoT) are considered to be the highly embryonic and most emerging arenas in research in the industrial or technical world now. This has brought about the inevitability of introducing or developing highly reliable, highly efficient, low cost, and low power sensor nodes to the market. Primary emphasis of wireless sensor network routing protocol is now on the coup of power preservation. Most of the modern publications have exposed so many protocols primarily intended to mineralize the energy consumption in wireless sensor networks. This thesis work recommends an enhancement to the gradient base hierarchical routing protocol technique introduced by Dr. Mozumdar in 2011. Proposed method introduces active/ idle mode for end devices with time division multiplexing to cut down the energy usage of battery powered sensor nodes. At the same time data aggregation at the access point and also backup route has been introduced to end devices to send data back to the base station when the parent node fails to communicate. It is easy to perceive from simulation results that the enhanced protocol has higher lifetime compared to the original protocol. As a closing section, boosted energy efficient hieratical routing protocol (EEHW protocol) is implemented in Contiki OS.
