1 Introduction

Wireless Sensor Networks (WSN) have become a low power, low cost means for
communicating data between sensor devices dispersed over an area. Many of
these applications call for small embedded wireless networking solutions to
substantially reduce the cost of all required components. Atmel

’s Route Under

MAC (RUM) with support for IPv6 and 6LoWPAN is a highly flexible stack solution
for these low cost applications. Providing Internet Protocol (IP) over low power, low
data rate wireless transceivers enables immediate interoperability with existing
wired networks. With an IPv6 foundation, each wireless node on the network can
be given a worldwide unique IPv6 address and directly communicate with any other
IPv6 device in the world without the need for any translation or a complex gateway.

Free to Atmel customers, the Atmel RUM/6LoWPAN networking stack proves to be
a ready and cost-effective solution for Wireless Sensor Networks.

2 AVR2070 8240B-AVR-06/09 2 Stack Architecture Route Under Mac (RUM) is a small 802.15.4 protocol developed by Atmel. This protocol routes packets at the MAC layer, as opposed to the application or IPv6 layer, which would be a route over scheme. The under comes from the fact that routing is done at ...

AVR2070 3 8240B-AVR-06/09 2.1 Overview of RUM A RUM network is constructed around a coordinator. The coordinator is the only node that keeps any state information about the network, so that the other nodes do not have to store any network information. This allows for low cost hardware for both route...
