The emerging Internet of Things (IoT) connects the physical world to the digital one and composes large networks of smart devices to support various applications. In order to provide a suitable communication in such networks, a reliable routing protocol is needed. In this paper, a modified version of an IPv6 Routing Protocol for Low-Power and Lossy networks (RPL), which has been standardized by...

IETF ROLL (Routing Over Low power and Lossy networks) Group proposes the RPL (IPv6 Routing Protocol for LLNs) for routing in low power and lossy networks. Though RPL is able to work on several routing metrics, the details of using these metrics are not completely specified in the standard. To meet different QoS requirements of the applications, adopting proper routing metrics is essential. In t...

Today, Low Power and Lossy Networks (LLNs) represent one of the most interesting research areas. They include Wireless Personal Area Networks (WPANs), low-power Power Line Communication (PLC) networks and Wireless Sensor Networks (WSNs). Such networks are often optimized to save energy, support tra c patterns di↵erent from the standard unicast communication, run routing protocols over link laye...

In recent years, IoT (Internet of Things) technologies have seen great advances, particularly, the IPv6 Routing Protocol for Low-power and Lossy Networks (RPL), which provides a powerful and flexible routing framework that can be applied in a variety of application scenarios. In this context, as an important role of IoT, Wireless Sensor Networks (WSNs) can utilize RPL to design efficient routin...

Status of This Memo This memo provides information for the Internet community. It does not specify an Internet standard of any kind. Distribution of this memo is unlimited. Abstract The application-specific routing requirements for Urban Low-Power and Lossy Networks (U-LLNs) are presented in this document. In the near future, sensing and actuating nodes will be placed outdoors in urban environm...

Internet of Things (IoT) has the potential to improve the way we interact with things. IoT envisions the idea of universal connectivity of everything which is defined as the global network of uniquely identifiable and addressable smart things posing the capability to interact and communicate with other smart things. Every smart object consists of a microprocessor, transceiver module, a sensor a...

In recent years, mobility support has become an important requirement in various wireless sensor network (WSN) applications. However, due to the strict resource constraints of power, memory, and processing resources in WSNs, routing protocols are mainly designed without considering mobility. Low-Power and Lossy Networks (LLNs) are a special type of WSNs that tolerate data loss. The Routing Prot...

Low Power and Lossy Networks (LLNs) are inherently dynamic nodes move or experience link perturbations. Routing packets in LLNs is generally performed by the IETF IPv6 Routing Protocol for Low-Power and Lossy Networks (RPL). To face the dynamics of LLN, RPL is helped by external mechanisms such as Neighbor Unreachability Detection (NUD) or Bidirectional Forwarding Detection (BFD). In this artic...

This paper tackles the mobile routing issues in low-power and lossy networks (LLNs). The IPv6 standard protocol for LLNs, termed (RPL), has mostly been investigated static LLNs it no explicit mechanism to support mobility. In addition, there is that works well LLNs. Considering importance of mobility many LLN applications, this work designs implements MobiRPL, an adaptive, robust, received sign...

The Internet of Things (IoT) has emerged as a paradigm over the last few years as a result of the tight integration of the computing and the physical world. The requirement of remote sensing makes low-power wireless sensor networks one of the key enabling technologies of IoT. These networks encompass several challenges, especially in communication and networking, due to their inherent constrain...
