Pratibha Sharma, Vinod Kumar Jain, Avesh Kumar Uprawal · 2018
Routing over Low Power and Lossy Networks (LLNs) is a key challenge in IoT, because of its resource constrained devices [11] [10]. Some IoT applications where mobility and device to device communication (i.e., P2P communication) are necessary, the routing protocol should exhibit these properties with less energy consumption. Many researchers have developed routing protocols for IoT that produce optimum P2P paths with reduced energy consumption, but only a few of them support mobility. In this paper, Enhanced Mobility Aware Energy Efficient Routing Protocol for Internet of Things (EMAEER) is proposed, which is an extension of MAEER [3] protocol that provides optimum P2P routes for mobile as well as static nodes. Only a subset of nodes participate in the route discovery process in the availability of mobile nodes that leads to less energy consumption. An additional mechanism is implemented for handling mobile nodes so that they will remain connected within the network. In this work, we have considered a real-time scenario where nodes can be deployed in a non-uniform density environment. We have analysed the performance of our protocol with some benchmark protocols RPL, P2P-RPL along with ER-RPL. Simulation results represent that our proposed protocol consumes 9.61% less energy and provide 12.31% better packet delivery ratio compare to ER-RPL, which is best performing protocol among the three benchmark protocols.
