Reference Paper:  Cooperative interaction among multiple RPL instances in wireless sensor networks-

Research Area:

IOT

Research Topic:

Contiki Cooja Simulator Projects in RPL Routing Protocol

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

Software Requirements:  Vmware workstation player, Instant Contiki-3.0

Aim and Objectives:  
This project aims to design and evaluate cooperative interactions between multiple RPL instances in wireless sensor networks using a contiki-cooja simulator.

Contributions:  
1. This project proposes a novel approach (Cooperative-RPL) that coordinates the RPL Instances to form energy-efficient coalitions according to their objective functions and network conditions.
2. To propose a mechanism to evaluate fairness in networks with multiple RPL Instances.
3. It evaluates the distribution of the existing network resources to address each instance-s different, and sometimes contradictory, objective function.

Performance Evaluation:  
The simulation scenario considers 60 sensing nodes randomly deployed in a 100 × 100 m2. The information they collect is gathered at the sink node, located in the middle of the sensing area.
Performance Metrics:
 •  PDR
 •  Energy Consumption
 •  Throughput
 •  Delay
 •  Control Packet Overhead
 •  Execution Time
 •  CPU Energy Consumption
