Accurately synchronized clocks are crucial for many applications in sensor networks. The Intelligent Hybrid Mac Protocol (IH-MAC) is designed to provide accurately synchronized clocks between neighbors. IH-MAC works in a completely decentralized fashion. Every node periodically broadcasts its time information. IH-MAC is the combination of both Q-MAC and Z-MAC. IH-MAC achieves high channel utilization during high traffic load. IH-MAC provides the internal synchronization which means consistent view of time across all nodes that makes robust against link and node failures. Due to high load it switches from broadcast scheduling to link scheduling. It uses the time synchronization method to allocate the time slots. IH-MAC uses Request to send and clear to send handshakes for low energy consumption. The objective of this paper is to increase the quality of service Hybrid MAC (IH -MAC) is used. The transmission power, throughput, delay and packet delivery fraction are measured. The IH-MAC protocol is simulated on the network simulator 2 setup. © 2006-2015 Asian Research Publishing Network (ARPN).
