Transmission of IPv6 Packets over IEEE 802.15.4 Networks

Abstract

Transmission of IPv6 Packets over IEEE 802.15.4 Networks Status of This Memo This document specifies an Internet standards track protocol for the Internet community, and requests discussion and suggestions for improvements. Please refer to the current edition of the "Internet Official Protocol Standards" (STD 1) for the standardization state and status of this protocol. Distribution of this memo is unlimited.

Mobility of IP based Wireless Sensor Nodes in Sensor-Grid infrastructure

“…So, network mobility is beyond the scope of this paper. 6lowpan uses flat address space which means that all nodes within one certain subnet share the same IPv6 prefix [2]. Mainly two different mobility scenarios may occur for the nodes.…”

Recommendation on Stable IPv6 Interface Identifiers

“…For example, [RFC6282] allows for the compression of IPv6 datagrams over IEEE 802.15.4-based networks [RFC4944] when the IID is based on the underlying link-layer address.…”

Problem Statement and Requirements for IPv6 over Low-Power Wireless Personal Area Network (6LoWPAN) Routing

“…LoWPANs are assumed to be those described in the 6LoWPAN problem statement [RFC4919], and in the IPv6 over IEEE 802.15.4 document [RFC4944], which has specified how to carry IPv6 packets over IEEE 802.15.4 and similar networks. Whereas IEEE 802.15.4 distinguishes two types of devices called full-function devices (FFDs) and reduced-function devices (RFDs), this distinction is based on some features of the Medium Access Control (MAC) layer that are not always in use.…”

“…However, neither the IEEE 802.15.4 standard nor the 6LoWPAN format specification ( [RFC4944]) define how mesh topologies could be obtained and maintained. Thus, 6LoWPAN formation and multi-hop routing can be supported either below the IP layer (the adaptation layer or Logical Link Control (LLC)) or the IP layer.…”

“…LoWPANs might be either transit networks or stub networks. Under the assumption that LoWPANs are never transit networks (as implied by [RFC4944]), routing protocols may be drastically simplified. This document will focus on the requirements for stub networks.…”
