Survey on Performance of Multipath Routing Protocol in Wireless Sensor Network

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 generous environment but nodes suffer from low battery power. So, energy efficiency and network life are main concerns in WSN. Zig Bee have 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 (Zig Bee tree routing), and STR (Shortcut tree routing) and ESTR (Extended Shortcut tree routing) are compared on the idea of various performance metrics like 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 of ESTR method. Performance of packet delivery ratio of STR is less as compared to AODV. Performance of end to end delay of STR is poor as compared to AODV. Extended STR is proposed to represent new ZigBee network routing protocol with improved performance of 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 ESTR method.
