Mobility increases the capacity of ad-hoc wireless networks

by Matthias Grossglauser, David Tse - IEEE/ACM TRANSACTIONS ON NETWORKING , 2002
"... The capacity of ad-hoc wireless networks is constrained by the mutual interference of concurrent transmissions between nodes. We study a model of an ad-hoc network where n nodes communicate in random source-destination pairs. These nodes are assumed to be mobile. We examine the per-session throughpu ..."

Adaptive clustering for mobile wireless networks

by Chunhung Richard Lin, Mario Gerla - IEEE Journal on Selected Areas in Communications , 1997
"... This paper describes a self-organizing, multihop, mobile radio network, which relies on a code division access scheme for multimedia support. In the proposed network architecture, nodes are organized into nonoverlapping clusters. The clusters are independently controlled and are dynamically reconfig ..."

Brownian Gossip: Exploiting Node Mobility

by unknown authors
"... Abstract — Several network services, including routing, resource-discovery, etc., require the knowledge of a node’s location, before invoking their respective algorithms. Locating a node is a challenging problem in large-scale ad hoc networks, especially when the nodes are mobile. Initial approaches ..."

Understanding Code Mobility

by Alfonso Fuggetta, Gian Pietro Picco, Giovanni Vigna - IEEE COMPUTER SCIENCE PRESS , 1998
"... The technologies, architectures, and methodologies traditionally used to develop distributed applications exhibit a variety of limitations and drawbacks when applied to large scale distributed settings (e.g., the Internet). In particular, they fail in providing the desired degree of configurability, ..."

, scalability, and customizability. To address these issues, researchers are investigating a variety of innovative approaches. The most promising and intriguing ones are those based on the ability of moving code across the nodes of a network, exploiting the notion of mobile code. As an emerging research field

Minimum energy mobile wireless networks

by Volkan Rodoplu, Teresa H. Meng - IEEE JOURNAL ON SELECTED AREAS IN COMMUNICATIONS , 1999
"... We describe a distributed position-based network protocol optimized for minimum energy consumption in mobile wireless networks that support peer-to-peer communications. Given any number of randomly deployed nodes over an area, we illustrate that a simple local optimization scheme executed at each n ..."

A message ferrying approach for data delivery in sparse mobile ad hoc networks

by Wenrui Zhao, Mostafa Ammar, Ellen Zegura - In Proc. of ACM Mobihoc , 2004
"... Mobile Ad Hoc Networks (MANETs) provide rapidly deployable and self-configuring network capacity required in many critical applications, e.g., battlefields, disaster relief and wide area sensing. In this paper we study the problem of efficient data delivery in sparse MANETs where network partitions ..."

can last for a significant period. Previous approaches rely on the use of either long range communication which leads to rapid draining of nodes ’ limited batteries, or existing node mobility which results in low data delivery rates and large delays. In this paper, we describe a Message Ferrying (MF

Mitigating routing misbehavior in mobile ad hoc networks

by Sergio Marti, T. J. Giuli, Kevin Lai, Mary Baker - Proc. ACM/IEEE MOBICOM , 2000
"... This paper describes two techniques that improve through-put in an ad hoc network in the presence of nodes that agree to forward packets but fail to do so. To mitigate this prob-lem, we propose categorizing nodes based upon their dynam-ically measured behavior. We use a watchdog that identifies misb ..."

Dur-ing extreme mobility, watchdog and pathrater can increase network throughput by 27%, while

Next Century Challenges: Mobile Networking for “Smart Dust”

by J. M. Kahn, R. H. Katz , K. S. J. Pister , 1999
"... Large-scale networks of wireless sensors are becoming an active topic of research. Advances in hardware technology and engineering design have led to dramatic reductions in size, power consumption and cost for digital circuitry, wire-less communications and Micro ElectroMechanical Systems (MEMS).

The missing ingredient is the networking and applications layers needed to harness this revolutionary capability into a complete system. We review

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.
