In a wireless sensor network, the nodes closer to the sink node transmit more data, and consume more energy. This phenomenon lead to more serious network congestion and higher packet loss probability. These series of problems are known as “hot area” effect. Based on the structure of the clusters’ networks in GAF protocol, some researches are carried out on the problems of unfair delay and packet loss. In this paper, a new DMAC protocol-based MAC algorithm is proposed as a supplement to ST-MAC, which is called EDMAC. In this new algorithm, a control information transmission scheduling was added to improve ST-MAC’s data transmission mechanism and a method of emergency priority is provided to ST-MAC to decrease the waiting time of the emergency data within a cycling period.
