چکیده

6LoWPAN defines how to carry IPv6 packets over IEEE 802.15.4 low power wireless or sensor networks. Limited bandwidth, memory and energy resources require a careful application of IPv6 in a LoWPAN. The IEEE 802.15.4 standard defines a maximum frame size of 127 bytes that decreases to 102 bytes considering the header overhead. A further reduction is due to the security, network and transport protocols header overhead that, in case of IPv6 and UDP, leave only 33 bytes for application data. A compression algorithm is necessary in order to reduce the overhead and save space in data payload. This paper describes and compares the proposed IPv6 header compression mechanisms for 6LoWPAN environments.

Performance evaluation and implementation of IP and robust header compression schemes for TCP and UDP traffic in static and dynamic wireless contexts

Modern cellular networks utilising the long–term evolution (LTE) set of standards face an ever–increasing demand for mobile data from connected devices. Header compression is commonly employed to minimise the overhead for IP–based cellular network traffic. In this paper, we evaluate the three header compression implementations used by these networks with respect to their potential throughput in...

Connecting Wireless Sensor Networks to the Internet -- a 6lowpan Implementation for TinyOS 2.0

A 6lowpan implementation for the TinyOS 2.0 embedded operating system has been developed. It supports the 6lowpan adaptation layer with handling of the Fragmentation, Mesh Addressing and Broadcast headers. The 6lowpan-specified HC1 compression of the IPv6 header and the HC UDP compression of the UDP header are supported as well as handling of the uncompressed headers. Although not all requireme...

Compression of Ipsec Ah and Esp Headers for 6lowpan Networks Draft-raza-6lo-ipsec-04

This document describes the header compression mechanisms for IPsec [RFC4301] based on the encoding scheme standardized in [RFC6282]. The IPsec Authentication Header (AH) and Encapsulated Security Payload (ESP) headers are compressed using Next Header Compression (NHC) defined in [RFC6282]. This document does not invalidate any encoding schemes proposed in 6LoWPAN [RFC6282] but rather complemen...

Forwarding Techniques for IP Fragmented Packets in a Real 6LoWPAN Network

Wireless Sensor Networks (WSNs) are attracting more and more interest since they offer a low-cost solution to the problem of providing a means to deploy large sensor networks in a number of application domains. We believe that a crucial aspect to facilitate WSN diffusion is to make them interoperable with external IP networks. This can be achieved by using the 6LoWPAN protocol stack. 6LoWPAN en...

6LoWPAN-GHC: Generic Header Compression for IPv6 over Low-Power Wireless Personal Area Networks (6LoWPANs)

RFC 6282 defines header compression in 6LoWPAN packets (where "6LoWPAN" refers to "IPv6 over Low-Power Wireless Personal Area Network"). The present document specifies a simple addition that enables the compression of generic headers and header-like payloads, without a need to define a new header compression scheme for each such new header or header-like payload. Information about the current s...
