| Abstract | ||||
| The sensor nodes power units in Wireless Sensor Networks (WSNs) contain small size batteries and low battery capacity. So, the primary concern in such networks lies in minimizing the energy dissipation. Due to this energy constraint, this paper presents an energy-aware MAC protocol for improving the lifetime of WSNs. The new approach overcomes a major drawback of existing Medium Access Control (MAC) protocols such as Sensor-MAC (S-MAC) and Multi-Layer MAC (ML-MAC), which do not take the initial node power into consideration, which may result in unfair power consumption among the nodes, especially for low-power nodes. The new approach aims to maximize the life time for low-power nodes, which leads to increasing the overall network life time. The experimental results show that the proposed MAC protocol saves energy more than both S-MAC and ML-MAC. The new approach saves energy of about 56.8% more than S-MAC protocol. It also achieves 33.7% energy saving compared to ML-MAC protocol. | ||||
