Research on Technology of Wireless Sensor Network

Wireless communication and embedded technology have made the wireless sensor network (WSN) possible. The sensors, which are deployed in an environment, are required to collect data from their surroundings, process the data, and send it to the sink. Traditional WSNs collect the data such as temperature and pressure. WSN has potential to design many new applications for handling emergency, military, and disaster relief operations that require real-time information for efficient coordination and planning. The self-organization and cooperation of wireless sensor network have opened up a broad application prospect. However, wireless sensor network has the characteristics of resource limitation and design constraint. Resource limitation means that sensor nodes have limited wireless communication range, limited power supply, low bandwidth, limited computing power, and storage capacity. Design constraint means that the design of wireless sensor network depends on its application purpose and the monitored physical environment. This paper first introduces the concept of wireless sensor and expounds the challenges brought by the characteristics of wireless sensor network. Secondly, this paper introduces the representative research work from the aspects of network standard communication protocol network management technology and data compression technology.
