RPL Routing Project Topics using Cooja Simulator for IoT

  •    The routing protocol for low-power and lossy networks (RPLs) is the routing layer protocol for IoT. The RPL is a proactive routing protocol for multi-hop communication. It is designed based on distance vectors, and it is operated on IEEE 802.15.4 MAC protocol. The RPL constructs the topology structure similar to a tree named Destination Oriented Directed Acyclic Graph (DODAG) and eases the packet routing. It takes one or more routing metrics to estimate the rank for DODAG construction. From rank estimation to topology construction, RPL uses various control messages.
  • Three control messages are defined as follows:
    • DODAG Information Solicitation (DIS): Used to respond to connected neighboring nodes about DODAG joining.
    • DODAG Information Object (DIO): DIO message periodically refreshes the information of the nodes about the version of DODAG, RPLInstanceID, DODAG version number, and DODAG ID.
    • Destination Advertisement Object (DAO): DAO helps build routes from root nodes to sensors.
  • • The RPL accounts for the Objective Functions (OFs) with link quality measurements and rank estimation to construct the DODAG to root devices separately and trickle algorithm. Recent researchers mainly focus on those techniques for enhancing the efficiency and security of routing layer protocol.

  • Critical Analysis of Objective Functions:
    • To understand the protocol behavior for different individual and combined metrics, it is prominent to evaluate the RPL over different scale and mobile environments.
    •  A structured algorithm is needed for Objective Function (OFs) and Minimum Rank Hysteresis Objective Function (MRHOF).
    • With the knowledge of routing path cost evaluation using different metrics, a generalized algorithm is developed to enhance RPL performance.
  • RPL objective functions using variant routing metrics:
    • ETX and Hop Count alone are insufficient to cover all the IoT needs.
    • According to the application requirement, the routing metric selection is a principal idea to improve the RPL performance.
    • A combination of three different metrics ETX, Content, and Energy related metrics, are used to enhance the design of the objective function of RPL for IoT applications. It explores the enhanced triggering technique in the designs of improved RPL.
