Extended Multipath Routing in Zigbee which Improves Performance Parameters

Abstract

As we know Wireless Sensor Network is the perfect solution for quick capturing, processing, and transmission of critical data. Sensor nodes are often deployed in a generous environment but nodes suffer from low battery power. So, energy efficiency and network life are the main concerns in WSN. ZigBee has low cost, low power consumption, and is beneficial in wireless sensor networks by selecting adequate communication protocol. Routing protocols like AODV (Ad- hoc on-demand distance vector routing), ZTR (ZigBee tree routing), and STR (Shortcut tree routing) and ESTR (Extended Shortcut tree routing) are compared on the idea of various performance metrics like the end to finish delay, routing overload, throughput, packet delivery ratio (PDR). The mathematical analysis and performance evaluation shows that ESTR achieves better performance as compared to other routing protocols. The overall evaluation shows that ESTR achieves better performance as compared to other routing protocols. But there are some limitations to the ESTR method. The performance of the packet delivery ratio of STR is less as compared to AODV. The performance of end to finish delay of STR is poor as compared to AODV. Extended STR is proposed to represent the new ZigBee network routing protocol with the improved performance of the Packet Delivery ratio (PDR) and delay against STR and AODV. We are introducing here Efficient Extended Shortcut Tree Routing method (ESTR) for further improvement of delays of the ESTR method.
