In wireless sensor network, packet loss due to buffer overflow of sensor nodes and the delay caused due to retransmission of that lost packet is a major problem. So, a big challenge is to improve the delay performance along with reliability of WSN. This proposed system is to broadcast sensed data to focus on delay performance. Also congestion at collector node due to duplicate sensed data in network is reduced by data aggregation, for this the authors compute a function at the collector node from the information gathered by spatially distributed sensor nodes.
