摘要：Wireless Sensor Networks (WSNs) have emerged as a new research technology in the distributed computing environment and plays a very important role in the pervasive computing to support various applications. It has a great potential to be utilized in battlefields and in different commercial applications like traffic surveillance, habitat monitoring, construction structures, smart homes, offices and many more. Research on several aspects of WSNs like energy efficiency, power management, rouunrting, topology control, data management and security are progressing extensively. In this technical paper a survey on recent trends in wireless sensor network research, different topologies, routing protocols, simulators and applications is carried out. A smart WSN consists of sensor nodes made of small electronic device and are deployed across a geographical area. These nodes carry out the sensing, processing and transmission of data from different physical environments. They depend on batteries which get drained very soon due to the computation and data transmission to other nodes. The architectures of WSN are mainly depending on application requirements. WSN is a multidisciplinary area of research where different applications developers, users, hardware and software designers need to work closely to implement an efficient application. The different characteristics of the sensor network like flexibility, fault tolerance, high sensing fidelity, low cost and rapid deployment create many new and exciting application areas.
