Wireless sensor and actuator networks (WSAN) are increasingly popular due to their abilities to detect and react to interesting events in the physical world. In this paper, a new indoor WSAN system in the context of pursuit evasion games (PEGs) is designed and implemented. Our goal is to take advantage of the WSAN capabilities to perform target tracking and capture. We design the system control model,...
Dissolved oxygen (DO) is an important indicator of the water quality in the modern sewage treatment It reflects the degree of self-purification capacity of the water. In this paper, we proposed a kind of wireless sensor network-based dissolved oxygen online collection terminal. The terminal, with the core of ARM (Advanced RISC Machines) microprocessor, combines of multi-sensor data fusion technology...
Traditional data collection terminals mainly utilize the method of wire, but on the occasion of scattered collection points and the scene complex environment, it is very difficult to wire. Based on wireless sensor network technology, a kind of data collection terminal with ARM9 as a core processor is proposed in this paper, which replaces the traditional actual wiring with wireless sensor network...
In wireless sensor networks where the sink is mobile, a node can conveniently hold an information packet until the sink comes closer. This allows to both decrease the number of wireless hops required to deliver the information to the sink and reduce energy consumption. Thus, mobility of sinks can be an effective way to minimize energy consumption. However, with the increasing energy efficiency in...
