Information-directed routing in ad hoc sensor networks

by Juan Liu, Feng Zhao, Dragan Petrovic, U. C. Berkeley - IEEE Journal on Selected Areas in Communications , 2005
"... In a sensor network, data routing is tightly coupled to the needs of a sensing task, and hence the application semantics. This paper introduces the novel idea of information-directed routing, in which routing is formulated as a joint optimization of data transport and information aggregation. The ro ..."

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 ..."

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 ..."

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 ..."

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 Secure Routing Protocol for Ad Hoc Networks

by Kimaya Sanzgiri, Bridget Dahill, Brian Neil Levine, Clay Shields, Elizabeth M. Belding-Royer , 2002
"... Most recent ad hoc network research has focused on providing routing services without considering security. In this paper, we detail security threats against ad hoc routing protocols, specifically examining AODV and DSR. In light of these threats, we identify three different environments with distin ..."

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 ..."
