<p>Wireless, unattended sensor networks offer a superior monitoring capability with unparalleled  flexibility. Traditional systems are typically restrictive in the rigidity of their positioning and topological  design requirements. Ongoing research continues to expand the potential for the use of these un-tethered  and autonomous systems ranging from the mundane, monitoring soil conditions for agricultural crops, to  the extreme of military operations, providing valuable intelligence to commanders in a variety of battlespace  conditions.  This thesis investigated the use of this type of system in what may be the most hostile of  environmental conditions from a wireless networking and communications point of view, the water. The  network will be required to organize, establish and maintain itself in a variety of dynamic conditions in or  on the water. Commercial off-the-shelf products developed by Crossbow Technologies were used in  developing the wireless, unattended sensor network consisting of single and multiple nodes. Nodes were  tested on a solid ground surface, on the surface of the water, below the surface of the water (not  submerged), and fully submerged. The most significant findings were attained with regard to range. Other  findings with regard to link quality, network formation, and network stability support results attained in  previous research.
