NIR: UWSN Routing Protocol Based on Node Neighbor Information

Recently, the Underwater Wireless Sensor Network has become the significant branch in the field of wireless sensor network, which extend people´s research into the underwater. However, because of the particularity of underwater circumstance, such as Mobility, high error rate and a low transmission rate etc, makes the Traditional land-based sensor network technology unsuitable for underwater application. Inspired by the Six Degrees of Separation, the article put forward the NIR: UWSN Routing Protocol Based on Node Neighbor Information, which chooses the next step via Greedy Strategy, and the ones with more neighbor node are given a higher rate. The simulation results show that NIR energy costs may remain at a relatively low level.
