Abstract
Provided are an energy-efficient communication method in a group information-based sensor network and a sensor network system using the method. A group exchanges group information and data with another group in order to provide an application service through inter-group cooperation in a sensor network. In this process, a target group is discovered, a communication path is established, and inter-group communication cycle information for energy-efficient communication is transmitted. On the basis of the group information and the communication cycle information, it is possible to minimize the network resource consumption and provide an energy-efficient inter-group communication method.
