Performance evaluation of a new cross layer protocol for sink powered underwater acoustic sensor networks

Türken, Hasan
The term Sink Powered Underwater Acoustic Sensor Networks (SPUASN) refers to a special configuration within the recent Remotely Powered Underwater Acoustic Sensor Networks (RPUASN) paradigm, where the data sink supplies energy to battery-free sensors that constitute the network. This thesis evaluates the performance of a new cross layer protocol, Cross Layer Power Adaptive CSMA/CA (X-PACCA), proposed for SPUASN. Simulation based performance evaluation is conducted both by investigating the effects of design parameters and by comparing with other protocols proposed for underwater sensor networks. Since X-PACCA is a cross layer protocol that integrates MAC, network and transport layer functionalities, comparisons are carried out separately by considering MAC and routing performance of the protocol in terms of end to end delay, packet delivery ratio and network throughput. This study also shows that, with appropriate selection of the protocol parameters, X-PACCA achieves low end-to-end delay, high packet delivery and high throughput performance.


Performance evaluation of an underwater acoustic sensor network communication protocol
Acar, Derya; Bilgen, Semih; Department of Electrical and Electronics Engineering (2014)
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 environme...
Distributed Connectivity Restoration in Underwater Acoustic Sensor Networks via Depth Adjustment
Uzun, Erkay; ŞENEL, FATİH; Akkaya, Kemal; Yazıcı, Adnan (2015-06-12)
In most applications of Underwater Acoustic Sensor Networks, network connectivity is required for data exchange, data aggregation and relaying the data to a surface station. However, such connectivity can be lost due to failure of some sensor nodes which creates disruptions to the network operations. In this paper, we present two algorithms, namely BMR and DURA, which can detect network partitioning due to such node failures and re-establish network connectivity through controlled depth adjustment of nodes ...
Sensitivity analysis for piezoelectric energy harvester and bluff body design toward underwater pipeline monitoring
Qureshi , Fassahat Ullah Qureshi; Muhtaroglu, Ali; Tuncay, Kağan (2017-01-01)
Monitoring of underwater pipelines through wireless sensor nodes (WSNs) is an important area of research especially for locations such as underground or underwater pipelines, where it is costly to replace batteries. In this study, a finite element sensitivity and comparative analysis for piezoelectric (PZT) energy harvester operating in a fluid flow is done to power underwater in-pipe WSNs. Two types of bluff bodies D and I-shaped are used for comparison. Finite element simulations results show that PZT ene...
Remotely powered underwater acoustic sensor networks
Bereketli, Alper; Bilgen, Semih; Department of Electrical and Electronics Engineering (2013)
The lifetime of underwater acoustic sensor networks (UASN) is constrained primarily by the power available to the battery-operated sensor nodes. Therefore, power efficiency has become a major design goal for UASN solutions thus far. To eliminate this challenge on the design of UASN, power harvesting is a promising solution, in which Remotely Powered UASN (RPUASN) nodes harvest and store the power available from a powerful external underwater acoustic source. In this study, the novel RPUASN paradigm is intro...
Self-deployment of mobile underwater acoustic sensor networks for maximized coverage and guaranteed connectivity
ŞENEL, FATİH; Akkaya, Kemal; Erol-Kantarci, Melike; Yilmaz, Turgay (2015-11-01)
Self-deployment of sensors with maximized coverage in Underwater Acoustic Sensor Networks (UWASNs) is challenging due to difficulty of access to 3-D underwater environments. The problem is further compounded if the connectivity of the final network is desired. One possible approach to this problem is to drop the sensors on the water surface and then move them to certain depths in the water to maximize the 3-0 coverage while maintaining the initial connectivity. In this paper, we propose a fully distributed ...
