Abstract
A wireless sensor network is a new technique for collecting and dealing with information, and is typically deployed to collect and monitor environmental parameters. In the future Internet, a wireless sensor network could provide direct and effective information for monitoring. Due to the characteristics of wireless sensor networks, they can be applied in many fields such as military defense, environmental monitoring, city management, agricultural control, and so on. In wireless sensor networks, the core technologies include routing, data transmission, etc. This paper surveys recent patents on wireless sensor networks which are mainly classified into five categories, namely power consumption, monitoring application, routing, data transmission and sensor nodes.
Keywords: Internet, node, power consumption, routing, wireless sensor network.
