The Node Distribution of the Random Waypoint Mobility Model for Wireless Ad Hoc Networks
, 2003
"... The random waypoint model is a commonly used mobility model in the simulation of ad hoc networks. It is known that the spatial distribution of network nodes moving according to this model is, in general, nonuniform. However, a closed-form expression of this distribution and an in-depth investigation ..."

From theory to practice: an overview of MIMO space-time coded wireless systems
- IEEE JOURNAL ON SELECTED AREAS IN COMMUNICATIONS
, 2003
"... This paper presents an overview of recent progress in the area of multiple-input–multiple-output (MIMO) space–time coded wireless systems. After some background on the research leading to the discovery of the enormous potential of MIMO wireless links, we highlight the different classes of technique ..."

On the Minimum Node Degree and Connectivity of a Wireless Multihop Network
- ACM MobiHoc
, 2002
"... This paper investigates two fundamental characteristics of a wireless multihop network: its minimum node degree and its k–connectivity. Both topology attributes depend on the spa-tial distribution of the nodes and their transmission range. Using typical modeling assumptions — a random uniform distri ..."

IMPORTANT: A framework to systematically analyze the Impact of Mobility on Performance of RouTing protocols for Adhoc NeTworks
- IEEE INFOCOM
, 2003
"... Abstract — A Mobile Ad hoc Network (MANET) is a collection of wireless mobile nodes forming a temporary network without using any existing infrastructure. Since not many MANETs are currently deployed, research in this area is mostly simulation based. Random Waypoint is the commonly used mobility mod ..."

Social Vulnerability to Environmental Hazards
- Social Science Quarterly
"... For over 50 years, hazards researchers have focused on a series of fundamental ques-tions: 1) what is the human occupancy of hazard zones? 2) How do people and societies respond to environmental hazards and what factors influence their choice of adjust-ments? 3) How do you mitigate the risk and impa ..."
