fundamental difference is the communication medium. Studies in this area indicated that acoustic communication is the typical physical layer
technology for underwater networks compared with electromagnetic waves and optical waves. Energy constraint, long delay and limitation in
bandwidth are greater challenges in underwater monitoring and other applications. In this paper, we will assess the performance of five UWSN
MAC layer protocols of the aquatic environment in terms of energy consumption and received throughput and then nominate three of them
based on previous assessment and compare them in terms of total drop packets and average end to end delay. Assessment is carried out by using
Aqua-Sim simulators for underwater sensor networks and NS2 based simulator installed in Linux environment

routing protocol in underwater wireless sensor networks by comparing between three routing
protocol are Vector-Based Forwarding Protocol (VBF), hop-by-hop vector-based forwarding (HHVBF)
and Vector-Based Void Avoidance (VBVA). The typical physical layer technology for underwater
networks is acoustic communication compared with electromagnetic waves and optical waves.
Energy constraint, long delay and limitation in bandwidth are greater challenges in underwater
acoustic sensor networks for monitoring and other applications.in this paper present the
performance evaluation of these protocols in term of energy consumption ,average end-to-end
delay and Packet delivery ratio. Comparison is carried out by using Aqua-Sim simulators for
underwater sensor networks and NS2 based simulator installed in Linux environment.

activities that need to implement through monitor the quality of specific
environment. In this thesis those activities and processes are presented by
assuming two important areas, the design of underwater wireless sensor
network and a proposal water quality index in Iraq using fuzzy inference
system.
In the first area (design of underwater wireless sensor network),thesis
focus on the performance assessment of five underwater wireless sensor
network (UWSN) Media Access Control (MAC) layer protocols namely;
(Broadcast MAC, Aloha, R-MAC, FAMA, and UWAN_MAC). These
protocols are used for the water environment in terms of energy
consumption and received throughput. Three of them are nominated
based on some previous assessment. They were compared in terms of
total drop packets and average end to end delay. Subsequently, an
investigation of the facts about what is the robust and energy efficient
routing protocol in underwater wireless sensor networks is presented.
This is done by comparing three important routing protocols, namely;
Vector-Based Forwarding Protocol (VBF), hop-by-hop vector-based
forwarding (HHVBF) and Vector-Based Void Avoidance (VBVA). The
performance evaluation of these protocols is achieved using metrics
energy consumption, average end-to-end delay and Packet delivery ratio.
Results of these evaluations and comparisons prove that UW-MAC
protocol is the most suited one with geographic routing protocols
especially VBF. Assessment is carried out by using Aqua-Sim simulators
for underwater sensor networks and NS2 based simulator installed in
Linux environment.
A robust and flexible index was made to be used as baseline for
all pollutants that need to be monitored. This has been done with fuzzy
inference system to present a work aimed to propose water quality index
in Iraq. Fuzzy logic is used for developing the traditional environmental
indices to eliminate the routine in assessment of water quality. As well as
to overcome the largest problems uncertainty and subjectivity in
traditional way; we called "FWQI". To evaluate the performance of the
index suggested with the real conditions, the case study was conducted on
Tigris River, Iraq. The data of water quality from different sampling
positions were taken. It was found that the achieved results from Fuzzy
Water Quality Index (FWQI) are less than the results obtained from the
regular method in final score of pollution by approximately 41.64% for a
specified period.
