Watchman-based Data Packet Forwarding Algorithm for Underwater Wireless Sensor and Actor Networks

The most unmanned area of the earth is covered with water; that is roughly 71.9% of the total area of this planet. A large quantity of marine life like world of sea-animals are present under this area, that is the reason underwater research is bounded due to unexplored benefits of such nice world. Due to addition of sensors and actors, the field Underwater Wireless Sensor and Actor Network (UWSAN) is a powerful discipline to explore and monitor the area of aquatic, rivers and submarine at-large place. UWSNs with hundreds of sensors receive information from different locations and transmitted the collected data to a particular user or hub, depending on the application and its requirements. A variety of routing protocols has been deployed in order to get information between deployed nodes. Providing stable data transmission, and forwarding the correct information from source to sink are basically a major concern when the area is large scale networks in some kind of shallow and deep water. The proposed algorithm is illustrated in this paper that used the concept of watchman nodes inside the sink zone areas. The watchman nodes are deploy to tackle the issue of stopped communication when the neighboring nodes are going to die. To evaluate the performance of these routing protocols several parameters are under study in this paper, like data delivery ratio, throughout and packet delivery/loss ratio. At the end the state of the art technique TCBDGA is compared with proposed algorithm WDPFA.
