Abstract
Power-aware protocol design is important due to the limited battery capacity of the mobile devices making up the ad hoc wireless network. The performance of the medium access control (MAC) scheme not only has a significant effect on the performance of the routing method employed, but also on the energy consumption of the wireless network interface card (NIC). Thus, a thorough energy-based comparative and performance study is essential to any bandwidth-based study. We explore the shortcomings of the MAC schemes proposed for ad hoc wireless networks in the context of power awareness herein. In addition, we investigate the potential energy consumption pitfalls of non-power-based and power-based routing schemes. Moreover, we introduce a thorough energy-based performance study of power-aware routing protocols for wireless mobile ad hoc networks. Our energy consumption model is based on an implementation of the IEEE 802.11 physical layer convergence protocol (PLCP) and MAC sublayers. We also present the statistical performance metrics measured by our simulations.
