Aloha based Cost Effective Medium Access Protocol in Underwater Wireless Sensor Networks

Underwater sensor networks; it is a rapidly developing area of research with a wide range of applications such as data collection in ocean, pollution monitoring and ocean sampling. One of the most researched areas is the coverage of underwater sensor networks, which are the basis of many applications. The coverage is usually related to how effectively a network is monitored by the sensor. There are major problems in the ocean or marine region, especially in water pollution. Underwater pollution generally causes acidification, plastic residues and toxins. Today, the determination of this pollution is carried out through a human surveillance monitoring process. Therefore, there is a need for an automatic and intelligent monitoring system to identify the formation of pollution. The proposed simulation model defines the intelligent sensor-based monitoring system that identifies and alarms the formation of underwater pollution. Aloha was chosen as the medium access protocol for the cost-effective system in which we designed the simulation model. The efficiency of the system has been shown to be more stable, cost-effective and manageable than the monitoring process involving the existing human surveillance by testing with the simulation model. When the sensor network load increases from 0 to 6, the highest performance ratio is obtained as 0.36 when the network load is 1. The delay value changes between 0.14 ms and 0.16 ms, while the lowest delay is acquired as 0.15 ms in the middle of simulation duration
