Implementation of Multichannel Technology in ZigBee Wireless Sensor Networks in Nodes Wake-up Mode
摘要
In wireless sensor networks, multiple channels are used to send parallel data to decrease interference. Low power and high reliability are among the features of multichannel technology in terms of wireless sensor network. Zigbee is a technology based on IEEE 802.15.4 standard which is designed a class of high level communication protocols, and it is used by small, low consumption digital radios for making personal wireless networks for such usages as home automation, data gathering from medical devices, and other needs with narrow band width for small projects requiring wireless communication. Reducing energy consumption, improving operational power, increasing correct packet sending rate, and delay are some issues related to the usage of multichannel technology. Therefore, in the proposed method using multichannel technology in ZigBee wireless sensor networks with state of nodes wake-up, it is attempted to resolve the aforementioned issues. The simulation results show that the proposed method decreases the delay, improves the operational power, and reduces the energy consumption.
