Dynamic Source Routing Protocol—A Comparative Analysis with AODV and DYMO in ZigBeebased Wireless Personal Area Network

The suitability of various applications with respect to wireless ad hoc networks and the corresponding scalability to such network extended to incorporate various other nodes is justified by ad-hoc networks with peer-to-peer nature. Different types of sensors are associated with each WSN node that is battery powered, operated and controlled by a microcontroller. Route to an intended destination is discovered only if the source node has a data packet to send in on-demand routing. Ad hoc On-Demand Distance Vector (AODV) routing protocol is extensively used as network layer protocol in Wireless Sensor Networks based on ZigBee (IEEE standard 802.15.4). The proposed application is aimed at a network with few number of WSN nodes suitable to a typical user home or private network forming Wireless Personal Area Network. The disadvantage of AODV is that it consumes more system resources and memory. Hence it is required to re investigate and find more appropriate protocol for the proposed application. In order to find out the suitable protocol set for the proposed application, this paper describes and published about the methodology and results of experimentation in the network layer of IEEE standard 802.15.4 ZigBee protocol stack with different types of On-Demand Distance vector routing protocols viz., AODV, DYMO and DSR, while keeping the MAC layer protocol Sensor MAC (SMAC) unchanged. In this process, values of different types of performance metrics viz., Throughput, Average end-to-end delay, average jitter and total packets received are measured and compared using Qualnet network simulator version 5.0.2 by varying number of hops and network traffic loads other applicable parameters during experimentation.
