Energy Enhancement Using Network Coding and Duty Cycle in Wireless Sensor Networks

A fundamental challenge in designing a wireless sensor network is to enhance the energy consumption which leads to improvement in network lifetime. the area around sink forms a bottleneck zone due to heavy traffic, which reduces the lifetime of sensor networks. the upper bounds of network lifetime can be estimated using network codin and duty cycle there are two types of sensor nodes are there in bottleneck zone: simple relay sensors and network coder sensors and outside the bottle neck zone leaf sensor nodes and intermediate sensor nodes are located. with proposed network coding and duty cycle methods. Energy efficiency of bottleneck zone increases this in-turn improves the lifetime of the network performance metrics are packet delivery ratio, throughput and energy consumption.
