LIFETIME IMPROVEMENT OF WIRELESS SENSOR NETWORK USING NETWORK CODING AND ADAPTIVE DUTY CYCLE

missions. Hence the lifetime of the  wireless sensor network is increased. This work archive to the enhancement of the energy efficiency of the bottleneck zone which in turn leads to overall improvement of the network lifetime by considering an network coded adaptive duty cycle WSN. Linear Network coding does not simply relay on the packets of information that they receive, the sensor nodes of a network take several packets and combine all of them together for the transmission and apply it to the  bottleneck zone. By applying the above techniques we finally achieve the increased overall lifetime of node. This proposed system investigates life time improvement approx 8% - 14%, and minimizing energy consumption
