Wireless detector networks have become very democratic in Holocene years. For detector network, S-MAC and T-MAC are used to improve the energy benefits by applying sleep control. Our ultimate aim is to achieve high power benefits under extended range of traffic and also promises shorter delay for this type of emergency and latency-sensitive messages and removed collision. In this project, we present the light weight Intelligent Hybrid MAC, a newer low power with QoS promising medium access control protocol for wireless detector networks. Our proposed Enhanced ACTIVITY CONTROL (Enhanced-IHMAC) is combines TDMA and CSMA with buffering technique. There are many applications of wireless detector network where it is really wanted to ensure the priority services for the emergency information. And also we have not used synchronization messages unlike our base model. Our proposed ACTIVITY CONTROL (Enhanced-IHMAC) protocol guarantees shorter latency for this type of emergency and latency-sensitive messages with low overhead and emergency scheduling.
