Our project aim is to increase the lifetime of Wireless sensor network using Virtual Backbone Scheduling and ERPMT method. In VBS Method Instead of creating a single backbone we are creating a Multiple overlapped backbones to work alternatively. This would increase the lifetime of WSN comparably. In ERPMT Method we divide the node energy into two ratios; one for the sensor node originated data and the other one is data relays from other sensors. Our proposed technique is evaluated by using the simulator NS2. The simulation results show that the life time of the network increases at the same time it provides highest system throughput. The performance is evaluated by considering the QoS parameters like data rate, packet loss ratio, Bandwidth, SNR value.
