A Cooperative Group-Based Sensor Network for Environmental Monitoring

Sensor networks can be used in many types of environments. The environmental monitoring is one of the most used. Communications in sensor networks should be as efficient as possible and collaborative methods can enhance their performance. In this work, we propose a monitoring group-based sensor network which uses the cooperation between groups. When a group detects an event, it warns the alert, jointly with the parameters measured, to its neighboring groups. Cooperation with other groups could change the direction of the alert propagation and the level of the alert. According this cooperation, the sensor network will be efficient and the sensors will have a longer lifetime.
