RPL (Routing Protocol for low-power and Lossy Networks) is a new attractive model that secures the networks from different routing risks. The dynamic environment and limited resources motivated the research towards identifying a stable, reliable, energy efficient, and scalable routing design. IPv6 over low-power Wireless Personal Area Network (6LoWPAN) is a standard RPL IPv6 routing protocol that provides Low power and Lossy Networks (LLNs) interoperability. In this research work, an energy efficient and optimization-based mobility management framework in RPL routing protocol was proposed (mRPL-based firefly optimization algorithm) to achieve a reliable and stable protocol. From the results, it can be inferred that the proposed system (mRPL+firefly optimizer) showed better performance with regard to the Packet_Delivery_Ratio (PDR), number of hops, End_To_End delay and power consumption when compared to existing systems: RPL, mRPL, mRPL+PSO, and mRPL+ACO. The experimental outcome showed that the proposed system improved the PDR on an average of 2.31% in comparison with existing systems.

RPL（低功耗有损网络的路由协议）是一种新的有吸引力的模型，可确保网络免受不同的路由风险。动态环境和有限的资源推动了该研究的发展，以寻求一种稳定，可靠，节能和可扩展的路由设计。低功耗无线个人局域网（6LoWPAN）上的IPv6是标准的RPL IPv6路由协议，可提供低功耗和有损网络（LLN）互操作性。在这项研究工作中，提出了一种在RPL路由协议中基于能源效率和优化的移动性管理框架（基于mRPL的萤火虫优化算法），以实现可靠稳定的协议。从结果可以推断出，建议的系统（mRPL + firefly优化器）在Packet_Delivery_Ratio（PDR），跳数，与现有系统（RPL，mRPL，mRPL + PSO和mRPL + ACO）相比，End_To_End延迟和功耗。实验结果表明，与现有系统相比，该系统平均可提高PDR 2.31％。
