Abstract EN
Considering the high energy consumption of image acquisition, computation, and transmission in wireless multimedia sensor networks (WMSNs), two-tier network structure is usually used to lighten the energy consumption burden on camera sensors.
Thus, a camera sensor can only be actuated when an event is detected by scalar sensors within its field of view (FoV).
In this paper, we study the event-driven camera actuation problem and propose a distributed collaborative camera actuation scheme based on sensing-region management (DCCA-SM).
The basic idea of this scheme is to divide the whole sensing field into many sensing regions which are covered by different sets of camera sensors.
During the running of the network, by forming a cluster of the scalar sensors in each sensing region, the events occurring in each sensing region can be managed by the scalar cluster head.
Therefore, by hearing from the scalar cluster heads, each camera sensor can know the exact coverage overlaps without changing information with the neighboring camera sensors.
Meanwhile, sensing-region management avoids repeatedly event reporting from scalar sensors.
In order to show the performance of the DCCA-SM, a simulation has been conducted.
The comparative performance evaluations demonstrate effectiveness and energy efficiency of the proposed scheme.
