Cross Layer Controlling Algorithm to Overcome Congestion in Underwater Wireless Sensor Network - 2021

Research Area:  Wireless Sensor Networks

Abstract:

Underwater Wireless sensor network posses several factors, which causes congestion, issues in the network, like mutual interference, many to one communication, and dynamic changes in the topology of the network. These factors make the network more vulnerable to the occurrence of congestion in the network. Congestion in underwater wireless sensor network leads to the possibility of occurrence of packet loss, over utilisation of node energy and drop in throughput of the network. In order to overcome these issues a cross layer congestion control scheme is introduced over the contention based MAC protocol. The channel information passed by the MAC layer was added with the details about ratio of buffer occupancy and congestion level in the local nodes. The cross layer protocol dynamically adjust the priority of accessing the channel in MAC layer and controls the data transmission rate to control the occurrence of congestion in the network. The performance of the cross layer network is compared with the hierarchical based and cluster based methods by simulating in NS2 simulator and hardware model is developed to analyse the real time constrains in hardware environment.
