Abstract
The main objective of this work is to propose a new routing protocol for wireless sensor network employed to serve IoT systems. The routing protocol has to adapt with different requirements in order to enhance the performance of IoT applications. The link quality, node depth and energy are used as metrics to make routing decisions. Comparison with other protocols is essential to show the improvements achieved by this work, thus protocols designed to serve the same purpose such as AODV, REL and LABILE are chosen to compare the proposed routing protocol with. To add integrative and holistic, some of important features are added and tested such as actuating and mobility. These features are greatly required by some of IoT applications and improving the routing protocol to support them makes it more suitable for IoT systems. The proposed routing protocol is simulated using Castalia-3.2 and all the cases are examined to show the enhancement that achieved by each case. The proposed routing protocol shows better performance than other protocols do regarding Packet Delivery Ratio (PDR) and latency. It preserves network reliability since it does not generate routing or data packets needlessly. Routing protocol with added features (actuating and mobility) shows good performance. But that performance is affected by increasing the speed of mobile nodes.
