Energy efficiency with mobility support plays an important role in Wireless Sensor Networks. Duty cycling mechanism is used to reduce energy consumption of idle listening and coordinates sleep and wake-up period of nodes to prolong the network life time. The delay sensitive applications require the duty cycle adjustment with network traffic conditions to accomplish energy efficiency and low latency. The proposed Energy Efficient and Mobility Aware Hybrid MAC (EMH-MAC) protocol with adaptive duty cycle reduce the delay for prioritized services. In this approach, the duty cycle is dynamically adjusted with mobility and queue length of priority packets. The proposed protocol offers better data transmission rates in high traffic load conditions and also saves energy in low traffic.
