Abstract:
Underwater Wireless Sensor Networks (UWSNs) have an important role in different applications, such as offshore exploration and ocean monitoring. In this paper, we improve the performance of the Clustering Vector-Based Forwarding algorithm (CVBF) by enhancing its behavior. Here, the whole network is divided into a predefined number of clusters and determining an internal bounded side with its own coordinates for each cluster. The main target of our proposed algorithm is to avoid the calculations taken for the nodes in which they never move away from its cluster. These nodes’ positions are near the cluster axis and far enough from the cluster boundaries. For this reason, we separate between the nodes that can move outside the clusters and the nodes that never move away. Simulation results demonstrate that the proposed algorithm reduces the energy consumption especially in dense networks, increases the packet delivery ratio especially in sparse networks, and decreases the average end-to-end delay in both sparse and dense networks. These advantages are emphasized when the algorithm is compared with five other powerful routing algorithms: VBF, Hop-by-Hop VBF (HH-VBF), Vector-Based Void Avoidance (VBVA), Energy-Saving VBF (ES-VBF), and the CVBF routing protocols.
