Coalesenses offers an IPv4 and
IPv6 dual network stack to easily integrate wireless sensor nodes into
the internet. Based upon the iSense OS and Networking Firmware,
it comprises all functionality required for connecting wireless sensor
networks with existing network installations using the internet protocol
family.
Within the sensor network, the
6LoWPAN protocol suite (including implementations of neighbor discovery,
header compression and fragmentation) is used to transmit IPv6
datagrams over the IEEE 802.15.4 link layer radio interface. The stack
supports both the Route-Over and Mesh-Under mode in the sensor network,
functionality for routers within the network as well as for 6LoWPAN
border routers is included.
Besides UDP and TCP, a HTTP server
including Digest Authentication is part of the stack. In addition, it
provides a full-featured Constrained Application Protocol (CoAP) server
(including the Observe Draft). Hence, the stack is ready to offer
Restful Webservices within your wireless network.
The IP stack is part of the iSense OS and Networking Firmware avaliable for free download together with documentation and demo applications. Like this, wireless sensor networks made up of sensor nodes built from the iSense modular hardware system can easily be connected to Ethernet installations using the Wireless Ethernet Gateway.
