Abstract
Significant advances in technologies led to the development of Wireless Sensor Network (WSN). WSN composes of large number of sensor nodes, which are tiny, low powered, densely deployed in an ad hoc fashion either inside a physical phenomenon to be sensed or very closely to it. The region around the sink forms a bottleneck zone due to heavy traffic flow, which reduces the lifetime of WSN. One of the constraints in the WSNs is limited battery power of the sensor nodes which in turn can reduce the lifetime of WSN. This paper attempts to improve the network lifetime by considering duty cycle, network coding and clustering techniques. The results show that the lifetime of the WSN can be enhanced by combining duty cycle, Network coding and clustering. Performance metrics like Energy Consumption, Packet Delivery ratio and Latency were also analyzed using NS2.
