Abstract
Due to effectiveness of network layer on general performance of networks, designing routing protocols is very important for lifetime and traffic efficiency in wireless sensor networks. So in this paper, we are going to represent an efficient and scalable version of depth-based routing (DBR) protocol that is limited by depth divisions-policy. In fact the new version is a network information independent routing protocol for acoustic communications. Proposed method by use of depth clustering is able to reduce consumed energy and end-to-end delay in dense underwater sensor networks (DUSNs) and this issue is proved by simulation.
Highlights
Underwater network is a new communication area for research in recent years
We are going to introduce our new improvement i.e. Energy Efficient and Low Delay-Depth-Based Routing (DBR) (EELD-DBR), with this assumption that network is working in dense mode, we wish to create some depth routing clusters for improving routing performance
We introduced our new improvement over DBR protocol, i.e. Energy Efficient and Low Delay-DBR
Summary
Underwater network is a new communication area for research in recent years. In these networks, acoustic. Using this type of channel creates high delay and low bandwidth links in underwater communications, inaccessibility to sun light and wired electrical resources in underwater space is a key limitation and creates energy constraints for the networks. A key routing scheme to apply in underwater sensor networks is Depth-Based Routing (DBR) protocol [1]. This protocol has excellent suitability for dense network application. It is wellknown that dense networks have challenges in energy consumption and link delay [2]-[4], so we select DBR as basic routing protocol in this investigation.
