A ROUTE STABLE ENERGY AND MOBILITY AWARE ROUTING PROTOCOL

Abstract

The Internet Of Things(IoT) is emerging as a necessary tool for the modernization of world. With the advancement in IoT comes the new challenges in many areas. One area among them is routing. Though routing in IoT is challenging but the more challenging task is routing in low power lossy networks (RPL). There are some critical applications for example healthcare, which requires the mobility issue to be resolved. Mobility in RPL is a new research area for many scholars and number of protocols are developed for the same. Some work integrate mobility in a way that avoid any disconnection of moving node before finding new connection while other just allow fast recovery after disconnection. This work is broadly divided into two parts. The first part is analysis of various mobility associated RPL protocols. The main focus is on the energy consumption, handover delay, signaling cost and route stability of various algorithms and categorize the studied protocols on the basis of their property. The next part enhances a protocol called EMA-RPL protocol, which originally produces unstable routes in which topology change is frequent. The proposed algorithm selects new parent node on the basis of mobile node’s speed and direction of motion. The proposed algorithm is compared to EMA-RPL on the parameters like handover delay, route stability and energy consumption.
