An open issue still to be addressed in low-power lossy networks (LLNs) is how the application requirements, the available transport services, the network layer routes, and the data link-layer resources are mapped efficiently. This can be explained by the fact that, in most LLNs, link-layer resources cannot be easily managed; this results in a best effort IP layer, and traffic engineering perfor...
RPL is the IETF standardized IPv6 Routing Protocol for Low-power and lossy networks (LLNs). The major effort therefore made on handling low data rate traffic. Meanwhile, Internet of Multimedia Things emerged as one hot topic Things. In LLNs, providing a descent quality service (QoS) along with user experience (QoE) multimedia applications challenging. High bandwidth significant computation capa...
RPL (Routing Protocol for Low Power and Lossy Networks) has been designed for low power networks with high packet loss. Generally, devices with low processing power and limited memory are used in this type of network. IoT (Internet of Things) is a typical example of low power lossy networks. In this technology, objects are interconnected through a network consisted of low-power circuits. Exampl...
wireless sensor networks (wsns) are one of the most interesting consequences of innovations in different areas of technology including wireless and mobile communications, networking, and sensor design. these networks are considered as a class of wireless networks which are constructed by a set of sensors. a large number of applications have been proposed for wsns. besides having numerous applic...
Internet of Things (IOT) vision is to connect almost everything to the Internet. IOT includes various networks such as Low-power and Lossy Network (LLN). LLN is a network of small smart devices communicating through low power and low-bitrate medium. Enhanced computation power of LLN small devices is a step toward the IOT reality. Internet Engineering Task Force (IETF) thinks about connecting LL...
IPv6 based Low-Power and Lossy Networks (LLNs) are emerging. Internet Engineering Task Force (IETF) has developed an IPv6 Routing Protocol for LLNs (RPL), which is widely considered as a feasible routing protocol for LLNs. However, routing loops and lack of a loop-free local route repair mechanism are two major open issues to be addressed in RPL. Based on the framework of RPL, this paper propos...
applications such as high definition viedeo reproduction, portable computers, wireless, and multimedia demand, and ever-increasing need for ligh-frequency high-resolution and low-power analog-to-digital converters. flash, two-step flash, and pipeline convertors are fast but consume large amount of power and require large area. to overcome these problems, successive approximation converter blo...
The smart grid relies on Advanced Metering Infrastructure (AMI) to function. Because of the significant packet loss and slow transmission rate wireless connection between meters in AMI, these infrastructures are considered Low-power Lossy Networks (LLNs). routing protocol an AMI network is crucial for ensuring availability timeliness data transfer. IPv6 Routing Protocol lossy networks (RPL) exc...
The routing protocol for low power and lossy network (RPL) started to be designed by the ROLL working group of IETF since the year of 2008. Until the RFC6550 was released, this standard with its routing algorithms and four application scenarios, such as home and building automation, industrial control, and urban environment, have been grounded. As a main jigsaw of the paradigm of the Internet o...
Interoperability is essential for the commercial adoption of wireless sensor networks. However, existing sensor network architectures have been developed in isolation and thus interoperability has not been a concern. Recently, IP has been proposed as a solution to the interoperability problem of low-power and lossy networks (LLNs), considering its open and standards-based architecture at the ne...
