Abstract
En 中文
This paper describes a design of network structure which combines Wireless Local Area Network (LAN) and Wireless Sensor Network (WSN). The network topology is employed in an enterprise scenario. At hardware side, we have designed a slim Access Point (AP) with embedded OpenWRT Linux System and a ZigBee Dongle and integrated them in a Plug and Play (PnP) manner. The ZigBee dongle has a programmer-friendly software interface, namely, AT Command. At the scene of this enterprise scenario, there are a great deal of battery-supplied ZigBee nodes. The unnecessary energy consumption of these ZigBee nodes can be an issue that needs to be solved. This paper proposes an innovative energy consumption saving algorithm for ZigBee end-devices. This algorithm can be used to adjust the transmission power adaptively in order to obtain optimistic transmission current. The deciding factors are the received signal strength indicator (RSSI) and Package Received Rate (PRR). Both factors are obtained from ZigBee Coordinator. Thereupon, the utility time of ZigBee nodes can be extended.
