Scalability Analysis of Depth-Based Routing and Energy-Efficient Depth-Based Routing Protocols in Terms of Delay, Throughput, and Path Loss in Underwater Acoustic Sensor Networks
In underwater acoustic sensor networks (UWASNs), nodes are either static or dynamic depending upon the network configuration and type of application. Direct or multi-hop transmissions are used to forward data toward the sink. Alternatively, sinks can also be mobile or static, depending on whether the application is real time or passive. The variety of nodes and sink deployments greatly affect the performance of routing protocols. In this chapter, we analyze the effects of node density and scalability on the performance of routing protocols in UWASNs. Two popular UWASNs protocols were selected for this purpose: the depth-based routing protocol (DBR) and energy-efficient depth-based routing protocol (EEDBR). DBR is a non-cluster-based technique that performs routing using only the depth of nodes, whereas EEDBR is a location-free scheme that uses both the depth and the residual energy of nodes to route data. The scalability of node deployment was used to check the efficiency of these schemes in the context of three parameters: packet delivery ratio, end-to-end delay, and path loss.
