Reference Paper:  An adaptive timer for RPL to handle mobility 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 analyze an adaptive timer for RPL to handle mobility in wireless sensor networks using the contiki-cooja simulator.

Contributions:  
1. This project proposes a new adaptive timer algorithm that considers the random trajectory of mobile nodes.
2. This algorithm is dynamically adjusted based on the time to leave to prevent mobile node disconnections.
3. The RPL protocol is improved by changing the metric used to elect the preferred parent.

Performance Evaluation:  
Cooja is the default simulator of the Contiki operating system, which implements RPL protocol and can emulate the behavior of real motes. Random network topologies were used in the simulations where 50 fixed sensor nodes with increasing mobile nodes were deployed.
