This survey explains about the inference of wireless broadcast for lossy wireless sensor networks data aggregation. In which each sensor node sensing its physical environment and generates information finally sent those data to a special node called the sink through multi hop communications. By using the information gathered from spatially distributed sensor nodes the network system is to compute a function at the sink. Both collecting information and in-network computation at intermediate forwarding nodes can considerably increase network effectiveness through dropping the number of transmissions. On the other hand, this method also increases the single packet information capacity and makes the system vulnerable to packet loss. The proposed In network aggregation provides performance improvement of our solution over unicast architecture with retransmissions also this improvement should be depends on the transmission range as well as the reliability constraint.
