Abstract
Underwater wireless sensor network (UWSN) is established in water bodies such as oceans, seas and rivers to observe the activity of military, to perform rescue operations and to do mining activity of resources. The sensor nodes communicate through acoustic channels. These nodes have limited battery life (energy), narrow bandwidth and a channel is incurred with delays and noise posing security thrust. The art of work presented different routing protocols in this era to utilize energy and bandwidth efficiently with less delay and to provide the security against black hole attack. However, these methods do not show an appropriate enhancement in the security and to utilize the bandwidth efficiently due to mobile environment. As a result of which, the delay also increases. In this paper a secured and bandwidth utilization path is enhanced using Bellman Inora Hex Hamming technique (BIHH), which not only improves the performance of the routing but also saves the energy. The presented approach is validated with network simulator.
Highlights
Underwater communication becomes necessary to the entire world to obtain necessary information about the underwater resources, to check the occurrence and frequencies of tsunamis and to monitor the warfare environment
In this algorithm prioritization concept is used to check the vertical angle at every anchoring sensor node till it reaches to destination which increases the complexity and reduces throughput
From the above theories and models, it has been observed that path has been optimized either by energy or choosing the shortest path between end nodes. Both the two may not be the optimum as the delay parameter is increased with these approaches, which in turn maximizes the consumption of energy and reduces the overall throughput and packet delivery ratio, so may not be optimum for real time applications
Summary
Underwater communication becomes necessary to the entire world to obtain necessary information about the underwater resources (e.g. minerals), to check the occurrence and frequencies of tsunamis and to monitor the warfare environment. These issues change the mindset of the research community to work in this era. An efficient path estimation technique is being presented using Bellman Inora Hex Hamming (BIHH) technique This protocol provides security to UWSNs against well-known attack called black hole attack which is very common type of attack to mobile sensor network.
