Evaluation of RPL Performance with Objective Functions for IoT Real Time Networks (LLNs)
A LLN has extended to various application domains includes healthcare appliances, alert systems and different applications to monitor and manage the devices. It also automates the systems by automating devices like fire, physical security devices which are helpful in different scenarios. In IoT Networks routing protocols are used to establish communication from one node to another node. In this Protocol, Objective Functions are used it to identify the route from the sender sensor node to root node or Base station based on different constraints and specifications. Most extensively used Objective Functions are: OF0 stands for Objective Function Zero and MRHOF stands for Minimum Rank with Hysteresis Objective Function. The moto of this paper is to analyse the implementation of both objective function RPL’s by arranging the sensor nodes in different manner and observing the change in packet delivery ratio and power consumption of nodes. Observations are done using Cooja simulator in Contiki Operating system. The observations reveal that there exists a relationship between arrangements of nodes in a network to the performance of RPL’s objective functions and power consumption of network.
