What is RPL in 6LoWPAN?

RPL (Routing Protocol for Low-power and lossy networks) is a specific routing protocol designed to optimize6LoWPAN (IPv6 over Low power Wireless Personal Area Network) operation. As 6LoWPAN suffers from resourceconstraints on battery, processor, memory and bandwidth, it affects the performance of the RPL protocol.

What is the idea behind the 6LoWPAN header compression?

The goal of this document is thus to define a TCP header compression scheme for 6LoWPAN, called LOWPAN_TCPHC, which allows to significantly reduce the TCP overhead. The TCP header compression and decompression is performed in the edge router between the 6LoWPAN and the external IP network.

What is the main difference between IPv6 and 6LoWPAN?

It is almost identical to a normal IPv6 implementation with the following two differences: 6LoWPAN only supports IPv6, for which a small adaptation layer (LoWPAN) has been defined to optimize IPv6 over link layers. Although 6LoWPAN is not bound to the IEEE 802.15. 4 standard, it is designed to utilize it.

What is an acronym of 6LoWPAN?

6LoWPAN is an acronym of IPv6 over Low-Power Wireless Personal Area Networks. 6LoWPAN is the name of a concluded working group in the Internet area of the IETF.

What supports RPL?

RPL can support a wide variety of link layers, including those with limitations, with potential losses or that are used in devices with limited resources. This protocol can quickly create network routes, share routing knowledge and adapt the topology in an efficient way.

What is RPL explain Dodag and Dio with respect to RPL?

In RPL, a node may use DODAG Information Solicitation (DIS) message to probe its neighborhood for nearby DODAGs. The DODAG Information Object (DIO) carries information that allows a node to discover a RPL Instance, learn its configuration parameters, select a DODAG parent set, and maintain the DODAG.

Where is 6LoWPAN used?

The 6LoWPAN system is used for a variety of applications including wireless sensor networks. This form of wireless sensor network sends data as packets and using IPv6 – providing the basis for the name – IPv6 over Low power Wireless Personal Area Networks.

What is the RPL protocol?

The RPL protocol is a distance vector proactive routing protocol that creates a tree-like routing topology called the destination-oriented directed acyclic graph (DODAG), rooted towards one or more nodes called the root node or sink node.
