As applications using WSNs spread, demands for various packet transmissions are increasing.But sensors in WSNs operate by batteries, an efficient energy control mechanism is required due to the limited available energy.It is important to reduce idle listening and packet collisions to prevent unnecessary sensor energy consumption.In this paper, we present a traffic-aware and super-frame adjustment MAC protocol for WSNs which we call TASA-MAC.The TASA-MAC protocol has a slot reservation and extending frame function according to the amount of transmitted traffic.These features make TASA-MAC suitable for time critical applications.The results show that TASA-MAC protocol can reduce the packet transmission delay and prolong the network lifetime in comparison to existing related MAC protocols.
