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 ..."

A Review of Current Routing Protocols for Ad-Hoc Mobile Wireless Networks

by Elizabeth M. Royer, Chai-Keong Toh
"... An ad-hoc mobile network is a collection of mobile nodes that are dynamically and arbitrarily located in such a manner that the interconnections between nodes are capable of changing on a continual basis. In order to facilitate communication within the network, a routing protocol is used to discove ..."

Energy Conserving Routing in Wireless Ad-hoc Networks

by Jae-hwan Chang, Leandros Tassiulas , 2000
"... An ad-hoc network of wireless static nodes is considered as it arises in a rapidly deployed, sensor based, monitoring system. Information is generated in certain nodes and needs to reach a set of designated gateway nodes. Each node may adjust its power within a certain range that determines the set ..."

Ad-hoc On-Demand Distance Vector Routing

by Charles E. Perkins, Elizabeth M. Royer - IN PROCEEDINGS OF THE 2ND IEEE WORKSHOP ON MOBILE COMPUTING SYSTEMS AND APPLICATIONS , 1997
"... An ad-hoc network is the cooperative engagement of a collection of mobile nodes without the required intervention of any centralized access point or existing infrastructure. In this paper we present Ad-hoc On Demand Distance Vector Routing (AODV), a novel algorithm for the operation of such ad-hoc n ..."

Energy Aware Routing for Low Energy Ad Hoc Sensor Networks

by Rahul C. Shah, Jan M. Rabaey , 2002
"... The recent interest in sensor networks has led to a number of routing schemes that use the limited resources available at sensor nodes more efficiently. These schemes typically try to find the minimum energy path to optimize energy usage at a node. In this paper we take the view that always using lo ..."

SEAD: Secure Efficient Distance Vector Routing for Mobile Wireless Ad Hoc Networks

by Yih-Chun Hu, David B. Johnson, Adrian Perrig , 2003
"... An ad hoc network is a collection of wireless computers (nodes), communicating among themselves over possibly multihop paths, without the help of any infrastructure such as base stations or access points. Although many previous ad hoc network routing protocols have been based in part on distance vec ..."

vector approaches, they have generally assumed a trusted environment. In this paper, we design and evaluate the Secure Efficient Ad hoc Distance vector routing protocol (SEAD), a secure ad hoc network routing protocol based on the design of the Destination-Sequenced Distance-Vector routing protocol

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 ..."

Location-Aided Routing (LAR) in mobile ad hoc networks

by Young-bae Ko, Nitin H. Vaidya - IN: INTERNATIONAL CONFERENCE ON MOBILE COMPUTING AND NETWORKING (MOBICOM’98 , 1998
"... A mobile ad hoc network consists of wireless hosts that may move often. Movement of hosts results in a change in routes, requiring some mechanism for determining new routes. Several routing protocols have already been proposed for ad hoc networks. This paper suggests an approach to utilize location ..."

Ariadne: A secure on-demand routing protocol for ad hoc networks

by Yih-chun Hu , 2002
