AbstractReal-time data of storm surge are much needed for developing effective prediction models and nowcasting of impending hazard potential. The crucial aspect of monitoring and transmitting information for extreme weather conditions in near real time is vitally important and would benefit from accurate, robust, and relatively inexpensive wireless sensing network systems. This article presents a detailed overview of the design, operation modes, system performance, and field testing of a prototype wireless sensors network (WSN) system for local multipoint storm surge measurements. Key differentiators for the prototype WSN system when compared to the existing infrastructure for monitoring water levels used by National Oceanic and Atmospheric Administration are (1) real-time data transmission, (2) ultra low cost, and (3) power-efficient system. The WSN system offers reliable field measurement employing single or multiple sensors and with features to upload data to either a local laptop or to the cloud for easy concurrent access to data for users located in any part of the world.

Improved Algorithm

Wireless sensors network has been widely used in a real-time monitor, percept or gather physical information such as light, temperature, humidity, noise or Concentration of harmful gas. With its simple and efficient characteristics, Ant colony algorithm has been widely used in WSN rout. An energy efficient rout algorithm based on ant was shown in this article, in which an energy-related descending parameter was used. The improved algorithm avoids excessive repetition use in the network link, in order to use the network energy effectively, and at the same time transmission rate is also guaranteed.
