Wireless Sensor Network is an up-and-coming technology that shows great promise for various innovative applications both for public and military. Wireless Sensor Networks (WSNs) are Ad-hoc wireless networks of typically consists of hundreds or even thousands of small low-cost sensor nodes that communicate in a wireless way. A sensor node is a small independent unit, often running on batteries, with hardware to sense environmental characteristics, a processor and a radio transceiver. All nodes send their sensed data to a central gateway node. Existing network protocols are not suitable for the WSN setting, since they often require a lot of information exchange. Therefore, suitable WSN protocols are required and their correctness and robustness is essential.
