Development of Virtual Backbone Scheduling Technique to Improve Lifetime of WSN

Now a day, Wireless Sensor Networks (WSN) is class of latest networking technology and it is becoming more popular. There are various research areas in the field of WSN like security, deployment, data aggregation, designing less power consuming devices, etc. Sensor nodes are the battery powered and it is not that much easy to recharge batteries of nodes. As we know that sensing, computing and transmission these are the main tasks of sensor nodes out of which for transmitting, the sensors require more energy. So to improve performance of the network in terms of network lifetime, it is necessary to minimize early depletion of sensor nodes. In this paper, we present new virtual backbone scheduling algorithm called energy and event based VBS to maximize the lifetime of a network by efficient energy utilization.
