A comprehensive minimum energy routing scheme for wireless ad hoc networks

Current minimum energy routing schemes in wireless networks only consider energy consumption for transmitting data packets. However most wireless devices also transmit some control packets (such as RTS and CTS in 802.11) besides data packets. Without considering the energy consumption for control packets, the existing minimum energy routing schemes tend to use more intermediate nodes, which results in more energy consumption and less throughput. We first propose more comprehensive energy consumption models that consider the energy consumption for data packets as well as control packets. Based on these models, we propose our minimum energy routing scheme. The simulation results verify that our scheme performs better than the existing minimum energy routing schemes in terms of energy consumption as well as throughput.
