Reference Paper:  IRH-OF: A New Objective Function for RPL Routing Protocol in IoT Applications-[2021]

Research Area:

IOT

Research Topics:

Contiki Cooja Simulator Projects in RPL Routing Protocol

Tools Languages:  Contiki-Cooja / Contiki NG simulator, Front End: Java, Back End: C

Software Requirement:  Vmware workstation player, Instant Contiki-3.0

Aim and Objectives:  This project aims to design novel objective functions for RPL routing protocol using the Contiki-Cooja simulator in IoT applications.

Contribution:  
1. Design a new objective function that considers the Radio Strength Signal Indicator and hop count along a path to the root.
2. To create two composite metrics such as RSSI and Hop count metrics.
3. Evaluate the performance metrics using the Contiki-Cooja simulator.

Performance Evalution:  The simulation network used a random topology for node distribution over a square space (200 m × 200 m ). The scalability comprises between 25 and 100 nodes to test the performances in different densities.
Performance Metrics:
 •  PDR
 •  Energy Consumption
 •  Convergence Time
 •  Latency
 •  CPU Energy Consumption
 •  Control Packet Overhead
 •  Throughput
