Improving the Performance of Wireless Sensor Networks by Reducing Delay and Maximaizing Life Span

In reducing the delay and exploit the life span of event-driven wireless sensor system for which actions occurs rarely. In such scheme, most of the power is enthusiastic when the radios are on, waiting for a packet to reach destination. Sleep - wake development is a successful instrument to extend the life span of this energy-constrained wireless sensor system. However, sleep - wake preparation might consequence in considerable interruption because broadcast lump requirements to wait for its next-hop converse lump to awaken up.
