A survey of context-aware mobile computing research

by Guanling Chen, David Kotz , 2000
"... Context-aware computing is a mobile computing paradigm in which applications can discover and take advantage of contextual information (such as user location, time of day, nearby people and devices, and user activity). Since it was proposed about a decade ago, many researchers have studied this topi ..."

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 ..."

Highly Dynamic Destination-Sequenced Distance-Vector Routing (DSDV) for Mobile Computers

by Charles E. Perkins, Pravin Bhagwat , 1994
"... An ad-hoc network is the cooperative engagement of a collection of Mobile Hosts without the required intervention of any centralized Access Point. In this paper we present an innovative design for the operation of such ad-hoc networks. The basic idea of the design is to operate each Mobile Host as a ..."

time dependent nature of the interconnection topology describing the links between the Mobile Hosts. Finally, we describe the ways in which the basic network-layer routing can be modified to provide MAC-layer support for ad-hoc networks.

Protocols for self-organization of a wireless sensor network

by Katayoun Sohrabi, Jay Gao, Vishal Ailawadhi, Gregory J Pottie - IEEE Personal Communications , 2000
"... We present a suite of algorithms for self-organization of wireless sensor networks, in which there is a scalably large number of mainly static nodes with highly constrained energy resources. The protocols further support slow mobility by a subset of the nodes, energy-efficient routing, and formation ..."

Managing Update Conflicts in Bayou, a Weakly Connected Replicated Storage System

by Douglas Terry, Marvin Theimer, Karin Petersen, Alan Demers, Mike Spreitzer, Carl Hauser - In Proceedings of the Fifteenth ACM Symposium on Operating Systems Principles , 1995
"... Bayou is a replicated, weakly consistent storage system designed for a mobile computing environment that includes portable machines with less than ideal network connectivity. To maximize availability, users can read and write any accessible replica. Bayou's design has focused on supporting apph ..."

ADEPT flex - Supporting Dynamic Changes of Workflows Without Loosing Control

by Manfred Reichert, Peter Dadam - Journal of Intelligent Information Systems , 1998
"... . Today's workflow management systems (WFMSs) are only applicable in a secure and safe manner if the business process (BP) to be supported is well-structured and there is no need for ad hoc deviations at runtime. As only few BPs are static in this sense, this significantly limits the applicabil ..."

A Touring Machine: Prototyping 3D Mobile Augmented Reality Systems for Exploring the Urban Environment

by Steven Feiner, Blair Macintyre, Tobias Höllerer , 1997
"... We describe a prototype system that combines together the overlaid 3D graphics of augmented reality with the untethered freedom of mobile computing. The goal is to explore how these two technologies might together make possible wearable computer systems that can support users in their everyday inter ..."

Dynamic Power Allocation and Routing for Time Varying Wireless Networks

by Michael J. Neely, Eytan Modiano, Charles E. Rohrs - IEEE Journal on Selected Areas in Communications , 2003
"... We consider dynamic routing and power allocation for a wireless network with time varying channels. The network consists of power constrained nodes which transmit over wireless links with adaptive transmission rates. Packets randomly enter the system at each node and wait in output queues to be tran ..."

Such performance holds for general arrival and channel state processes, even if these processes are unknown to the network controller. We then apply this control algorithm to an ad-hoc

Providing robust and ubiquitous security support for mobile ad-hoc networks

by Jiejun Kong, Petros Zerfos, Haiyun Luo, Songwu Lu, Lixia Zhang - IN ICNP, 2001 , 2001
"... Providing security support for mobile ad-hoc networks is challenging for several reasons: (a) wireless networks are susceptible to attacks ranging from passive eavesdropping to active interfering, occasional break-ins by adversaries may be inevitable in a large time window; (b) mobile users demand “ ..."
