Performance Comparison Of Routing Protocols For Zigbee Wpan
A wireless sensor network (WSN) is adhoc network. Each node in WSN will participate in routing process, based on the dynamic activity of the network connectivity. The peer- to-peer nature of wireless ad hoc networks makes them suitable for a variety of applications where coordinator can\'t be relied on, and may improve the scalability of wireless ad hoc networks. The WSN consists of few nodes to several hundred nodes, where each node is connected to one or more sensors. The topology of the WSNs can vary from a simple star network to an advanced multi-hop wireless mesh network. The propagation technique between the hops of the network can be routing or flooding. In on-demand (or reactive) routing protocols for ad hoc networks, a node attempts to discover a route to some destination only when it has a packet to send to that destination.
While many routing protocols are competent for using them in Wireless Sensor Networks, it is commonly found that AODV (Ad hoc On-demand distance Vector) routing protocol is often used in IEEE standard 802.15.4 ZigBee protocol stack. As there are many protocols reported in literature, it is required to revisit all the suitable protocols to find, if any, more suitable protocol especially for on demand routing (reactive) protocols. In this paper reactive protocols AODV, DSR and DYMO are surveyed and the summary of the characteristics of all these protocols are presented. Qualnet 5.0.2 network simulator is employed to analyze the important characteristics like throughput, average end-to- end delay, average jitter and total packets received by varying the number of hops under low, medium and heavy loads.
