Network lifetime is always an important topic in wireless sensor networks. The case of Wireless Multimedia Sensor Networks present additional features such as the fact of transmitting multimedia rich data or the fact of having directional sensing areas. This paper presents a scheduling scheme for clustered nodes according to overlapped Field of View (FoV) regions. This approach schedules nodes applying coordination and collaborations among members of clusters to sense the environment while each cluster covers a specific region defined by the degree of overlapping FoV. The objective of this mechanism is to increase power conservation by avoiding similar sensing and redundant processing. Evaluation shows that the proposed scheduling reduces the average energy consumption and thus improves network lifetime.
