Since most of sensor networks are usaully not designed with security in mind, it is difficult to add a security on their design. Because of the limitation of a resource, most of sensor nodes use broadcasting communication. It means that adversaries can interfere or distrupt the other nodes. As an one of security protocol, In-Network can find the inner attckers before the data packet arrives to the base station. In-Network assumed that all check node was deployed uniformly. But in the actual field, sensor nodes are deployed randomly. When the check node is deployed to one side, the other side can be exposure to adversaries.
In this paper, we proposed inhanced security protocol againt inner attackers and the energy efficiency in wireless sensor networks using weighted Node. We adopted weighted node mothod to In-network protocol and then we can set check nodes on the whole sensor network uniformly.
