Abstract

Wireless sensor network is consists of randomly or fixed distributed sensor nodes to monitor physical or environmental conditions, such as temperature, pressure, wind speed, sound and etc. These nodes will sense the surrounding conditions and send their data through the network to administrator. However, the network efficiency is restricted due to the issue of the energy conservation in sensor nodes as it is powered by batteries with limited capacity. Thus, an enhanced Ad-hoc On Demand Vector (AODV) routing protocol which has the potential to increase the sensor network’s lifetime was introduced. An algorithm of the enhanced AODV routing protocol are designed, simulated and analyzed in this study by using TinyOS software. Simulation and analysis of data were carried out for various distributed sensor nodes and simulation time to determine the efficiency of the sensor network. The average throughput (kbps) of the enhanced AODV routing protocol shows an increment of 351%, packet delivery ratio by 1.2% and the end-to-end delay (ms) is reduced by 75% when compared to the AODV routing protocol for the 10 nodes with simulation time of 100 seconds. From the results shown, this modified routing protocol has the optimum simulation time of 150 seconds for all three different numbers of distributed sensor nodes which shown the highest efficiency of the sensor network.
