Performance Comparison of Opportunistic Routing Schemes in Wireless Sensor Networks

Opportunistic routing is considered a promising direction for improving the performance of wireless sensor networks (WSN). In opportunistic routing, the intermediate nodes collaborate on packet forwarding in order to achieve high throughput in the face of lossy links. That makes the next node selection process crucial. In this paper, we are presenting an opportunistic routing protocol for wireless sensor networks. We also examine three extensions of that protocol, based on different next node selection criterion. We illustrate how each extension works and we evaluate and compare their performance in terms of energy consumption, delivery ratio and packet latency.
