Coding-Aware Opportunistic Routing for Sparse Underwater Wireless Sensor Networks

In underwater wireless sensor networks (UWSNs), the nodes are sparsely deployed over a large sea area due to their high design cost and manufacturing cost. Opportunistic routing protocols promising forwarding technique for various UWSNs. However, many opportunistic suffer from void problem in sparse scenarios. Hop count-based inherently alleviate this by periodically maintaining topological information of node. Nevertheless, robustness these degrades channel variation node movement paper, we propose coding-aware method UWSNs (CORS). CORS, use adaptively expand candidate set. On basis, with coding strategy is developed join interflow network CORS. addition, sliding window-based algorithm provide effective gains low overhead. Then, decoding designed reduce Simulation results show that CORS significantly improves upon performances existing
