Abstract: Wireless sensor networks (WSNs) generally focus on information gathering capacity of various applications and depends on the application types that may require certain quality of service (QoS) guaranteeing reliable transmission of data. However, providing QoS support is a challenging issue due to unreliable wireless links, highly resource constrained nature of sensor nodes and harsh operation environments. In this paper we investigate the utility of reactive routing protocol (AODV) in wireless sensor network to achieve improvements in throughput, packet delivery ratio and energy consumption per successful data delivery (ECSSD). Performance gains in the order of 30-50 % could be achieved by altering path update rules for table driven routing schemes (DSDV)
