Safieh Khodadoustan, Majid Hamidzadeh . Tree of Wheels: A new Hierarichal and Scalabale Topology for Underwater Sensor Networks. Wireless Information Networks & Business Information System. WINBIS, 2 (None 2011), 16-25.
Underwater Wireless Sensor Network (UWSN) is a new network paradigm that is being proposed to explore, monitor and protect the oceans. Some of the Underwater Sensor Nodes applications include oceanographic data collection, pollution monitoring, offshore exploration, disaster prevention, assisted navigation and tactical surveillance applications. The topology and model of communication play crucial roles in UWSNs. Very different topologies for UWSNs have been proposed which some of them are two- dimensional and three dimensional. In this paper we have presented a new topology called tree of wheels (ToWs) that is very suitable for three dimensional (3D) domains like aquatic environments. This topology is hierarchical and scalable which is capable of adapting itself to large numbers of nodes and overcoming distributed localization. With accurate connectivity degree and hierarchal level we can exactly estimate number of nodes which we are going to deploy for this environment. Furthermore, this topology can solve some other problems such as coverage and self-localization. ToWs has some specific properties that we will investigate them and explore its advantage and disadvantage.
