Tmote-Sky

Tmotesky.png
The Tmote Sky module is programmed through the onboard USB connector. A modified
version of the MSP430 Bootstrap Loader, msp430-bsl, programs the microcontroller’s flash.
Tmote Sky has a unique hardware circuit that prevents spurious resets. This hardware circuit
makes it necessary for a special sequence to be sent to the module in order to program it.
By invoking msp430-bsl, verify you have the patched BSL by looking for the “telos” keyword.
Version 1.39-telos-7 or later is required for Tmote Sky.
Seems very easy to create the mesh network on TmoteSky

Contiki has several AVR platforms, the latest being atmega128rfa1, which is pretty much a superset of the 
Raven's 1284p+AT86RF230 combination and could use the Raven code with very little change.

This application note provides a detailed hardware description of the individual function blocks of the sensor terminal board (STB). 
The STB is used in conjunction with an Atmel  radio controller board (RCB) in order to provide various interfaces for evaluating and creating wireless sensor type applications.

The contiki git repo has a functioning 128rfa1 port. It basically is a clone of the raven port with SPI access replaced by internal access to the extended io space registers.

The biggest advantage of IP based Wireless Sensor Networks is their ability to be seamlessly connected to the Internet. 
A device which passes data from the lowpan to ordinary network is called a "border router". 
Such a device must support at least two network interfaces: 802.15.4 for the lowpan, and 802.3 or 802.11 for the uplink

Not to take anything away from this board. But Synapse Wireless makes some firmware for the ATMega128RFA1 that run on this board and is intended for mesh networking. 
They also make two products around this chip, the RF200 and the SM200. While it may not sound appealing initially, it is very nice. 
You can upload code over the air. The code you program the nodes is python. There are nice features such as rpc calls that make it a very flexible system. 
If nothing else, check them out as an improved xbee replacement.

I have managed to make the SparkFun demo board work with the Synapse Wireless. 
I ended up purchasing the license for the bootloader hex which was suppose to work on these boards,  but they did not. 
I ended up using the hex file from Synapse RF200 board (RF200 uses Atmega128RFA1)and then I would change the MAC address 
so the Sparkfun board would have its own unique MAC in the network.

Synopsis

Most used platform for Contiki is the combination of MSP430F1611 TI low power CPU + CC2430 TI 2.4GHz 802.15.4 RF chip. It is the best choice for minimum effort Contiki or TinyOS nodes

Using above combination is the easiest way to go with Contiki as it is the most tested and is the 'official' chipset.
MSP430 family is very friendly to work with and has the best Low-Power characteristics than any other CPU family.
CC2430 is used by the open source Contiki and TinyOS more than other RF-chips. But there is not a low cost board available.
The MSP430 + CC2430 available boards are also expensive, starting at $85


ATmega128RFA1 CPU+RF 2.4GHz 802.15.4 chip seems to be the best choice for a WSN platform (August 2011). The technical characteristics are very good.

Large Flash, RAM,EEPROM (128K,16K,2K)
RF section has one of the best [reception-transmittion total gain]
RF section is already used in the open source WSN-OS as it is the same with the Atmel RF chip RF230
Commercial RF modules exist already at competitive pricing
OpenHardware projects already exist
Contiki port exists
Atmel proprietary Zigbee stacks
SYNAPSE ATmega128RFA1 based boards are the best engineered board regarding hardware, RF performance and Software.
It is possible to use Contiki Software to Synapse ATmega128RFA1 boards (or any other ATmega128RFA1 board)
It is already tested to use Synapse .HEX to other ATmega128RFA1 boards (Sparkfun board)
Dresden has very good quality ATmega128RFA1 boards with all RF-approvals
Sparkfun and Zigduino board are openhardware so can help in understanding and probably design a new board
Atmel has good documentation and reference designs on how to design a ATmega128RFA1 board
Synapse, Dresden, Sparkfun, Zigduino, Our-own design, can use all the same Software commercial or open-source
