“…Even greater energy savings is possible when the adaptive-transmission protocol is integrated with an energy-aware cross-layer routing protocol as in [5]. It is well known (e.g., [5][6][7]) that a routing protocol that seeks only to minimize energy consumption gives excessive delay and low probability of successful delivery for packets that must be relayed through the network. (All performance measures, such as delay and success probability, are end-to-end performance measures, and delay is measured in packet intervals.)…”

“…(All performance measures, such as delay and success probability, are end-to-end performance measures, and delay is measured in packet intervals.) The routing protocol of [5] employs a metric that represents a link's energy requirement, which is provided by the adaptive-transmission protocol, and a different metric that conveys link quality information, which is furnished by the physical layer. We refer to a routing protocol that is based on a combination of these two metrics as a hybrid routing protocol.…”

“…A combination of link metrics is also employed in [6] and [ 7] to avert the poor performance of minimum-energy routing. Unfortunately, significant increases in energy consumption are required by the combinations of link metrics that give good compromises between energy conservation and service quality (e.g., [5,7]). We show that if additional cross-layer information is available in networks with multimedia traffic, then our new protocol uses less energy than the hybrid routing protocol of [5] and accommodates the quality-of-service (QoS) priorities of the traffic.…”

Conservation of energy is important in a packet radio network, but reliance on energy-efficient routes for all types of traffic leads to large delays and low success probabilities in many situations. We describe and evaluate protocols that select routes according to the service priorities of the traffic. Energy conservation is emphasized for delay-tolerant traffic but sacrificed for delay-intolerant traffic, which gives good performance for both types of traffic.KEY WORDS: Packet radio networks; multimedia routing protocols; frequency-hop spread spectrum; ad hoc wireless networks.

“…We designed, implemented in simulation, and evaluated an energy-efficient routing protocol for frequency-hop wireless networks, and the results are summarized in [PRW02a] and [PRW04b]. The link resistance measures provide a protocol that accounts for energy consumption and link quality in the selection of routes in a wireless network that exhibits time varying propagation losses and interference.…”

“…Such measures are required if the routing protocol is to take advantage of the potential energy savings that are made possible by the adaptive-transmission protocol. The first integrated energyefficient protocol suite for routing and adaptive transmission in FH wireless networks is described and evaluated in [PRW04b]. Several routing metrics are compared, and tradeoffs among energy efficiency, delay, and packet success probability are investigated.…”

Results are reported for basic research in mobile wireless communication networks for tactical applications including investigations of new methods for error-control coding and decoding, modulation and demodulation, channel access, adaptive transmission and routing,, and broadband antenna design. Research results are presented on adaptive, energy-efficient, distributed protocols for mobile wireless networks that must operate effectively over unreliable communication links in highly dynamic environments and handle multimedia traffic. The dominant feature of the research is the exploitation of interactions among protocols to capitalize on the opportunities and overcome the impediments presented by the tactical communications environment and capitalize on the differences in quality-of-service requirements for mixed-media traffic. The interactions among protocols involve not only the exchange of information but also the active cooperation of different classes of protocols to accomplish the common objective of reliable, energy-efficient distribution of information. The research accomplishments include establishing and taking maximum advantage of a strong coupling of the various protocol layers with physical-layer functions such as receiver processing, modulation and demodulation, error-control coding and decoding. New protocols have been developed and evaluated for directional antennas, and broadband antennas have been designed and tested for use with spread-spectrum communications and other wideband waveforms. The development of side information in physical-layer operations and its effective utilization in soft-decision decoding, adaptive transmission, and adaptive routing are fundamental elements of the communication techniques and adaptive protocols that have been designed and evaluated.
