**5. Conclusion**

In this chapter a mechanism for management the wireless multimedia sensor nodes, was described. The mechanism, first, clusters nodes according to their scale of similarity in covering the environment; second, selects and schedules members of established clusters to monitor the sensing region which is divided among clusters. The members of each cluster are scheduled with an exclusive frequency based on the number of members in the cluster and the scale of overlapping among fields of view of the cluster members and thus the monitoring efficiency is increased. Moreover, because of the established intra cluster coordination and collaboration, sensing subsystem of multimedia nodes are optimized to avoid redundant and overlapped sensing. Thus, the capability of energy saving is considerably enhanced with respect to ordinary duty-cycling manners of environment monitoring by WMSNs. On the other hand, optimizing the data sensed by sensing subsystem results in conservation of energy in the transmission and processing subsystems since they meet less amounts of multimedia data to be transmitted and/or processed by the network nodes. Results show how this mechanism prolongs the network lifetime along with a better monitoring performance.
