An Opportunistic Routing Protocol for Underground Wireless Sensor Networks

Recently, most researches in the area of wireless sensor networks are limited to the ground environment, so the demand for underground wireless sensor networks is increasing. However, the underground environment is different from the ground environment in that there are some critical problems in reliability due to the large path loss of the underground. Therefore, in this paper we propose an opportunistic routing protocol for improving the reliability in the underground environment. Through the test-bed experiments, the proposed routing protocol is compared with other routing protocols.
