Installation and Management :The installation and management of underground sensors are much more difficult than aboveground networks because digging a hole and finding sensor underground are not easy tasks.Thus, before the deployment of underground sensor networks, the network and topology should be designed to minimize installation and management costs. Replacing the battery of underground sensor is also quite difficult due to their locations .For the sake of minimizing energy consumption of underground sensors operation, efficient sleep mode and long data reporting interval can be adopted.
