Sensor nodes in Wireless Sensor Network (WSN) are responsible for sensing the environment and propagating the collected data in the network. The communication between sensor nodes may fail due to different factors, such as temporal variations of the wireless channel, interference, hardware failures, and energy depletion. Hence, robust design of WSNs in order to be resilient to such failures is ...

In most oil pumping units have been using manual control in the oilfield. In this paper, wireless network based automatic control is proposed for OPU system. This proposed network can sequentially realize automatic data sensing, automatic malfunction detection, remote data transmission, intelligent data organization and management, automatic malfunction warning, and state report via RF module s...

We consider a design problem in which a one-dimensional array of sensors, connected via a wireless network, is used to track a moving vehicle. Individual sensors occasionally lose the vehicle, but can relocate it with aid from neighboring sensors. Communication between sensors is costly, so we accordingly optimize the communication protocol within a class of broadcast-type protocols to maximize...

Wireless sensor networks consist of energy-constrained sensor nodes operating unattended in highly dynamic environments. In this paper, we advocate a systematic decentralized approach towards the design of such networks based on utility functions. A local utility function is defined for each sensor node in the network. While each sensor node “selfishly” optimizes its own utility, the network as...

Wireless sensor networks have opened opportunities for new applications and attracted users from domains beyond computer system design. Sensor network design is challenging. It is generally an ad hoc process carried out by embedded system experts. In this dissertation, we argue that human efforts necessary to the design of sensor networks can be reduced with the help of high-level specification...

Protocol design for a Wireless Sensor Network (WSN) must jointly take many aspects into account, owing to the embedded nature of the devices, and the needs for energy efficiency, scalability, self-organisation and robustness to heterogeneous and unplanned environments: all these are crosslayer issues. As usual for wireless systems, protocol design normally includes a heuristic design phase, fol...

Wireless sensor networks(WSN) are an exiting emerging technology that scientists believe to become a part of every day life in the next few years. However, at this time many issues in wireless sensor networks remain unresolved. This paper studies the architecture of a neural wireless sensor network designed to identify technical condition of the base station of wireless sensor networks ,and thi...
