Mobility-Aware Parent Selection for Routing Protocol in Wireless Sensor Networks using RPL

Recently, mobile devices have been introduced in various Wireless Sensor Networks (WSNs) applications in order to increase data collection efficiency. Mobility and resources optimized management are still open challenging issues for the success and proliferation of the Internet of mobile things. Routing plays an important role in the overall architecture of the IoT. The existing routing protocol RPL has a very low reactivity to mobility making it inefficient and open to further research improvements. In this paper, the RPL protocol has been improved to support mobility on the network. We created a continuous connection by reducing the number of hand-offs using the hop count metric. This led to the reduced network overhead and the increased data delivery rate. To simulate the proposed protocol, the Contiki 6LoWPAN/RPL stack has been used. Obtained simulation results show that proposed protocol outperforms both the RPL and the MRPL protocols in terms of packet delivery rate, delay, network overhead and energy consumption.
