Recently, surveillance systems for public safety have become more intelligent through context awareness. Basically, traditional surveillance systems require power and networking infrastructure to operate the system and to transmit recorded data. These requirements increase the cost of system installation and maintenance. This paper proposes a wireless video sensor network platform for public safety...
Energy harvesting is required for the uninterrupted operation of Wireless Visual Sensor Networks (WVSNs). Solar energy is considered one of the effective energy harvesting sources for WVSN applications. In this paper, we propose an efficient energy management scheme for solar-powered WVSNs. The proposed scheme aims to maximize the overall quality of captured video while maximizing the network operation...
This paper proposes a method to prolong the lifetime of event-driven wireless video sensor networks. The proposed method provides the operating point of each node by firstly selecting the route to the sink node in an energy-aware fashion. Then it finds the lifetime-maximal encoding bit-rate utilizing the event statistics and the analytic power consumption models of major functional blocks in the target...
We proposed a scheme to improve the lifetime of multi-camera system and the quality of its captured image by appropriate sharing of such resources among camera nodes as battery and memory based on low-power wireless communication links among camera nodes. The proposed scheme determines which camera node captures the event and which camera node stores the captured event by jointly considering residual...
A mobile wireless camera (MWC) captures scene as it moves around, and then, stores the scene after compression. In this paper, we propose a novel method to extend battery lifetime by intermittently transmitting the compressed data to the base station (BS) through wireless transmission when the distance between MWC and BS is shorter than a given threshold distance; otherwise, compressed data are stored...
