The widely used activities of underwater wireless sensor networks (UWSNs) are data gathering, pollution monitoring, seismic monitoring and undersea exploration. Power supply is the major need of acoustic sensors which are used in UWSNs. The main complication in underwater sensor network is the replacement of batteries, limited bandwidth as well as high propagation delay. Firstly, to extend the life time and to reduce the energy consumption of the network the concept of Energy efficient of distributed unequal clustering (EEDUC) algorithm is used. This algorithm consists of unequal clustering model, election of cluster head, its establishment and transmission of data. Secondly, in order to reduce the packet collision we introduced new discovery of route and maintenance of route phase in the routing protocol. The main idea of this phase is the construction of low overhead routing protocol in order to control the …
