Design of Low-Power Router for Wireless Sensor Networks Based on Zigbee

Abstract

To solve the problem that the routing nodes in traditional wireless sensor networks need to be powered on all the time, a routing node which can wake up from sleep is designed and manufactured with CC2530 and cc2591 chips. In hardware, a low-power sleep chip and the peripheral circuit are selected, and a new routing protocol is used in software, The new protocol makes the routing node sleep periodically and wake up synchronously. When the node needs to send packets, it first retrieves the available routes in the routing table maintained by itself and then sends them. If the ACK packet returned by the routing node is not received after two consecutive transmissions, the routing link is invalid and a new route needs to be found. When new routes are available, update the routing table and synchronize the clock. Experimental results show that the routing node works stably and has low power consumption.
