Energy efficient spherical divisions for VBF-based routing in dense UWSNs

Three main problems for wireless sensor networks are communication traffic, energy consumption and routing security. In this paper we are going to analyze performance improvement of an underwater sensor network in dense mode applications via creation of forbidden regions in spherical divisions. Obviously, non-essential nodes deletion from packet forwarding process or routing process is an idea for network parameters enhancement in network theory. In this literature, our goal is only energy consumption and deletion process over physical routing space finally causes improvement in energy consumption and also network reliability/network lifetime. However, PDR are not worse than previous conditions and it is necessary to say that our scheme is useful.
