Wireless sensor networks plays an important role in many applications where the data sensing and transmitting to the sink needs authentication. Applications Wireless sensor networks applications are Volcano and fire monitoring, perimeter surveillance and urban sensing etc . Because of Physical tampering of nodes, information may be compromised and may cause large amount of errors in the aggregation computed at the base station. When a node is compromised it takes more time for transition and causes loss of information.The technologies such as multipath routing, spanning tree have lot of limitations while routing the information.Thus in-network data average technique reduces the communication overhead , time consumption and power consumption[1] .Thus an in-network data aggregator called "Synopsis Diffusion" method , which is robust and scalable against errors caused by the attacker nodes. Thus Synopsis Diffusion algorithm provides security in wireless sensor networks. An "Attack-Resilient algorithm" generates the true aggregation by eliminating the falsified bits in the aggregation hierarchy .
