We are using OPNET for:
Studying a model to achieve power savings in IEEE 802.11a-based Mobile Ad Hoc Networks (MANETs). In this configuration in particular, power is a crucial QoS parameter, as devices directly communicate between each other, hence increasing the energy consumption. Our aim is to present a model that preserves energy by sending information at the minimal power required to reach the destination with a specified Packet Error Rate (PER). Furthermore, with smart antennas processing at the physical layer, we can achieve further power savings, as we can obtain the required PER by sending data with lower power. As a further step of our work, we seek to improve the spatial reuse by proposing a new Medium Access Control (MAC) protocol.
