xbee sensor network

Hi,

Im working on a Cross Country Skiing project and need to analyze biomechanics using motion sensors, IMU.

Since the sensors are fasten on the skier while moving I need to set up a wireless sensor network.

Im not a Xbee expert only using xbee series 1 p2p communication between a receiver and a sender.

The setup consists of three different motion sensors IMU (left arm, right arm and one at the back of the skier) and they need to communicate with the computer.

What kind of Xbee do you recommend me to purchase? series 1 or 2? do i need to set up a mesh network (connector, router, end device)?

Thanks in advance for considering this question.

I will be using three 9 Degrees of Freedom - Razor IMU’s
