Power-Aware Routing in Mobile Ad Hoc Networks

by Mike Woo, Suresh Singh, C. S. Raghavendra , 1998
"... In this paper we present a case for using new power-aware metrics for determining routes in wireless ad hoc networks. We present five different metrics based on battery power consumption at nodes. We show that using these metrics in a shortest-cost routing algorithm reduces the cost/packet of rout ..."

On the Scalability of IEEE 802.11 Ad Hoc Networks

by Lifei Huang Huang, Ten-hwang Lai
"... The IEEE 802.11 standards support the peer-to-peer mode Independent Basic Service Set (IBSS), which is an ad hoc network with all its stations within each other's transmission range. In an IBSS, it is important that all stations are synchronized to a common clock. Synchronization is necessary f ..."

Investigating the Energy Consumption of a Wireless Network Interface in an Ad Hoc Networking Environment

by Laura Marie Feeney, Martin Nilsson - In IEEE Infocom , 2001
"... Energy-aware design and evaluation of network protocols requires knowledge of the energy consumption behavior of actual wireless interfaces. But little practical information is available about the energy consumption behavior of well-known wireless network interfaces and device specifications do not ..."

Power-Saving Protocols for IEEE 802.11-Based Multi-Hop Ad Hoc Networks

by Yu-Chee Tseng, Chih-Shun Hsu, Ten-yueng Hsieh , 2002
"... Power-saving is a critical issue for almost all kinds of portable devices. In this paper, we consider the design of power-saving protocols for mobile ad hoc networks (MANETs) that allow mobile hosts to switch to a low-power sleep mode. The MANETs being considered in this paper are characterized by u ..."

Geography-informed Energy Conservation for Ad Hoc Routing

by Ya Xu, John Heidemann, Deborah Estrin - ACM MOBICOM , 2001
"... We introduce a geographical adaptive fidelity (GAF) algorithm that reduces energy consumption in ad hoc wireless networks. GAF conserves energy by identifying nodes that are equivalent from a routing perspective and then turning off unnecessary nodes, keeping a constant level of routing fidelity. GA ..."

The broadcast storm problem in a mobile ad hoc network

by Sze-yao Ni, Yu-chee Tseng, Yuh-shyan Chen, Jang-ping Sheu - ACM Wireless Networks , 2002
"... Broadcasting is a common operation in a network to resolve many issues. In a mobile ad hoc network (MANET) in par-ticular, due to host mobility, such operations are expected to be executed more frequently (such as finding a route to a particular host, paging a particular host, and sending an alarm s ..."
