| Power efficiency issues are investigated across layers for use in tactical communications among battery-operated wireless sensor networks (WSNs) and wireless MANET nodes. Fundamental limits, practical guidelines, specific algorithms at the physical, data link, and application layers as well as performance analysis of tactical networks are developed when power optimization (as opposed to, e.g., throughput or delay, pursued by existing approaches) is the ultimate goal. Challenges addressed include the harsh interference ... |

| In free-space optical communication, the intensity of a laser beam is modulated by a message, the beam propagates through free-space or atmosphere, and eventually strikes the receiver. At the receiver, an optical sensor converts the optical energy into an electrical signal, which is processed to reconstruct the original message. The promising features of this communication scheme such as high-bandwidth, power efficiency, and security, render it a viable means for high ... |

| Recent interest in ocean exploration has brought about a desire for developing wireless communication techniques in this challenging environment. Due to its high attenuation in water, a radio frequency (RF) carrier is not the optimum choice. Acoustic techniques have made tremendous progress in establishing wireless underwater links, but they are ultimately limited in bandwidth. A third option is optical radiation, which is discussed in this paper. One drawback of underwater ... |
