Bottleneck Zone Analysis in WSN Using Low Duty Cycle in Wireless Micro Sensor Network

In Wireless Sensor Network (WSN) to enhance the network lifetime it’s a fundamental challenge. To enhance the network lifetime, the area around the sink node forms a bottleneck zone due to the heavy traffic flow which limits the network lifetime in WSN. To improve the energy efficiency of the bottleneck zone which leads to overall improvement of network lifetime by considering low duty cycled WSN For efficient communication paradigm has been adopted in the bottleneck zone by low duty cycle. The sensor nodes are generally classified into two groups: simple relay sensors and network coder sensors. The relay nodes simply forward the received data, whereas, the network coder nodes transmit using the network coding algorithm. More volume of data will be transmitted to the sink hence due to this energy efficiency of the bottleneck zone increases. This improves the overall lifetime of the network.
