Simplified AODV with Urgent Data Indication (sEAODVu): An Energy Efficient Routing Protocol for Zigbee Network
ZigBee is the emerging industrial standard for ad-hoc wireless networks based on IEEE 802.15.4, having characteristics such as low data rate, low price, and low power consumption. It is widely used in wireless sensor networks for remote monitoring, home-appliance networks, and industrial automation. It supports tree and mesh routing. A major concern in Wireless Sensor Networks (WSNs) is energy conservation, since battery-powered sensor nodes are expected to operate for a long time (for months or even years). AODV, an on-demand routing protocol is used for ZigBee mesh networks. The high number of control packets, makes AODV unsuitable for certain applications that requires energy efficient communications.
