Energy‐efficient Zigbee‐based wireless sensor network (WSN) occupies a major role in emergency‐based applications. The foremost drawback of such applications is maintaining the battery power because frequent changing is not possible in those conditions. In the earlier days, several researches created new model MAC protocols in terms of increase the lifetime of the WSN. But still, there is a research gap particularly in emergency applications. In order to improve the lifetime of such applications, we introduced a novel hybrid MAC protocol, namely, special purpose energy‐efficient contention‐based hybrid MAC (SPEECH‐MAC) protocol. This protocol includes dual hop concept considerably to save the energy. Both the single hop network and the dual hop networks are developed, and the results are analyzed. Prioritization mechanism for SPEECH‐MAC protocol is introduced to analyze the emergency conditions in detail. In summary, according to the simulation, the calculated parameters are total residual energy, end‐to‐end delay, packet drop, packet delivery ratio, and network throughput.

SPEECH-MAC：用于WSN和Zigbee网络的基于专用节能竞争的混合MAC协议

节能的基于Zigbee的无线传感器网络（WSN）在基于紧急情况的应用中占据重要地位。这种应用的最主要缺点是保持电池电量，因为在那些条件下不可能频繁更换。在早期，一些研究就增加WSN的寿命创建了新的模型MAC协议。但是，仍然存在研究缺口，尤其是在紧急情况下。为了延长此类应用程序的寿命，我们引入了一种新颖的混合MAC协议，即专用基于节能竞争的专用混合MAC（SPEECH-MAC）协议。该协议包括双跳概念，可大大节省能源。开发了单跳网络和双跳网络，并对结果进行了分析。引入了SPEECH-MAC协议的优先级机制来详细分析紧急情况。总之，根据模拟，计算出的参数为总剩余能量，端到端延迟，数据包丢失，数据包传输率和网络吞吐量。
