Wireless sensor network supports reliable monitoring of the given network based upon the data transmitted from the sensors. However, the feasibility can be maintained only when the delivered data are fairly reliable without any damage. Since data error is not an uncommon event in wireless sensor networks, the validity of the decision making strongly depends upon the stableness of the data analysis...

In wireless sensor networks, sensor nodes collect and forward environmental data back to the base station via multi-hop communications and nodes closer to the base station take relatively heavier communication loads. Therefore, an attacker may identify the location of the base station and cause security breaches by analyzing the network traffic. In this paper, we create traffic decoys that also sustain...
