Sensor-medium access control (S-MAC) protocol is a well-known MAC protocols designed for wireless sensor networks (WSNs). In this paper, we examine security vulnerability in S-MAC and analyze the power consumed at each stage of S-MAC according to vulnerability of denial of service (DoS) attack. From our analytical results, it can be induced that there is a need for a power-efficient authentication scheme which provides reliability, efficiency, and security for normal S-MAC communication. To our knowledge, this is the first comprehensive case study of possible DoS vulnerability and its power consumption in S-MAC. Our results can be used to design a power-efficient secure communication mechanism for WSN.
