The business applications such as weather forecasting, traffic management, weather forecasting, traffic management, etc., are enormously adopting Internet of Things(IoT). While scaling of these applications are fast, the device/sensor capabilities, particularly in terms of battery life and energy efficiency is limited. Despite of intensive research conducted to address these shortcomings, Wireless IoT Sensor Network(WIoTSN) still cannot assure 100\% efficient network life. Therefore, the core objective of the thesis is to provide an overview of energy efficiency of proactive(OLSR) and reactive(DSR and AODV) data routing protocols by scaling the size of network, i.e. number of sensor nodes, data packet size, data transmission rate and speed of mobile sink node. It also reviews the importance of security in WIoTSN. The two approaches, such as literature review and simulation testing, are used to achieve the objective of the thesis. The literature review provides information about reactive and proactive protocols and their mechanism for route discovery. Similarly, the network simulator tool NS3 is used for running simulation to evaluate the performance of selected routing protocols for energy efficiency. The thesis results showed the effect of scaling the parameters selected for experimental purpose on the energy efficiency of proactive and reactive data routing protocols. The simulation results prove that the reactive protocol DSR outperforms another reactive protocol AODV and proactive protocol OLSR in energy efficiency. From the security perspective, the thesis also emphasizes its need in IoT and suggest to minimize wasteful resources in WIoTSN and use them by restructuring the network for secure energy-efficient data routing protocols.
