Abstract
The commercialization of detection and surveillance systems by sensor networks has recently become more popular in various industries and in ordinary life. Wireless sensor networks (WSNs) may be utilized in areas such as military defense systems, u-care services, and disaster prevention systems. WSNs, which have three primary elements, should be able to communicate through a combination of network and sensor functions. When the size of a sensor network is small, the cost of building it accounts for a large fraction of the total cost. In large-scale sensor networks, however, maintenance costs to replace nodes when they are out of order, and batteries used for wireless communications, greatly increase, in addition to the cost of constructing them. Therefore, measures to detect and respond to sensor faults in a sensor network, as well as a mechanism to predict the energy consumption of sensors, are necessary. Accordingly, this paper proposes a measure to detect and deal with sensors by dividing WSN into fixed WSN and mobile WSN. This paper also suggests a method to predict and express the energy consumption of a sensor network.
Conclusions
A measure to detect and cope with the failure of a sensor in a sensor network and a mechanism to predict the energy consumption of sensors are necessary. For the construction of a WSN environment, several sensors—and appropriate protocols for communication among them—are required. With regard to protocols for communication among sensors, sensors are diverse and their uses vary. For this reason, the establishment of an optimal environment is not easy. In addition, to place and test sensors in a target area for verification of theoretical content incurs a high cost.
In placing sensor nodes, large-scale sensor nodes should be used together with placement algorithms. To discover and correct errors with these sensor nodes, an enormous amount of time and effort are consumed, and checking each sensor node is virtually impossible. Accordingly, this paper proposed a measure to detect and deal with sensors by dividing WSN into fxed WSN and mobile WSN. Tis paper also suggested a method to predict and express the energy consumption of a sensor network.
