Özet:Underwater acoustic sensor networks constitute a popular research issue, regarding which researchers have especially focused on energy efficiency problem. Methods to minimize energy consumption have been investigated in terms of network layers, especially data link and routing layer. However, RPUASN (Remotely Powered Underwater Acoustic Sensor Networks), which is a recent proposal, solves this problem by including acoustic energy sources and sensor nodes which can harvest the emitted energy in the environment. Sink Powered Underwater Acoustic Sensor Networks (SPUASN) is a particular kind of RPUASN, in which the sink node also operates as acoustic energy source. X-PACCA which is a recently proposed protocol for SPUASN is a cross layer solution including data link, routing and transport layers. In this study, to be able to evaluate the performance characteristics of X-PACCA protocol, an event-based simulator is developed in MATLAB. To validate the simulator, CSMA and DACAP protocols are implemented in this simulator, and their latency and throughput characteristics are investigated and compared with published references. Then, X-PACCA protocol is implemented in this simulator and its performance is evaluated in terms of average end-to-end delay and packet delivery ratio. The present work extends earlier similar studies and shows that parameter value choice for X-PACCA protocol is important to achieve low latency and high packet delivery ratio.
