From Encounters to Plausible MobilityI
"... Inferring plausible node mobility based only on information from wireless contact traces is a difficult problem. Working with mobility information allows richer protocol simulations, particularly in dense networks, but requires complex set-ups to measure. On the other hand, contact information is ea ..."

SniffMob: Inferring Human Contact Patterns using Wireless Devices
"... The size of existing data sets regarding human mobility and person-to-person contact has been limited by the laborintensive nature of the data collection techniques employed. In this paper, we propose a practical data collection system which is automatic and transparent to the user, requires only in ..."

installing new software, and uses the multiple sensing capabilities provided by current commodity mobile devices. This approach allows the scale and duration of these human contact studies to increase by several orders of magnitude and allows for the collection of location and contact information about
Optimization of radio measurements exploitation in wireless mobile networks
"... Abstract — Radio measurements play a crucial role in mobile wireless networks as they are input of Radio Resource Management (RRM) mechanisms, needed to assess mobile network reliability and to supervise the planned coverage area. Nevertheless, these measurements are used in their crude state withou ..."

without any additional intelligent treatment whereas they are a rich and unexploited source of information for the network. In this paper, we propose a new approach for the manipulation of existing radio measurements in wireless mobile networks. The goal is to optimize the use of these measurements
Ooi, “Analysis and implications of student contact patterns derived from campus schedules
- in MobiCom ’06: Proceedings of the 12th annual international conference on Mobile computing and networking
, 2006
"... Characterizing mobility or contact patterns in a campus environment is of interest for a variety of reasons. Existing studies of these patterns can be classified into two basic approaches – model based and measurement based. The model based approach involves constructing a mathematical model to gene ..."

to generate movement patterns while the measurement based approach measures locations and proximity of wireless devices to infer mobility patterns. In this paper, we take a completely different approach. First we obtain the class schedules and class rosters from a university-wide Intranet learning portal
Downlink Power Allocation for Multi-class CDMA Wireless Networks
, 2002
"... In this paper we consider the downlink power allocation problem for multi-class CDMA wireless networks. We use a utility based power allocation framework to treat multi-class services in a unified way. The goal of this paper is to obtain a power allocation which maximizes the total system utility. I ..."

. In the wireless context, natural utility functions for each mobile are non-concave. Hence, we cannot use existing techniques on convex optimization problems to derive a social optimal solution. We propose a simple distributed algorithm to obtain an approximation to the social optimal power allocation
Robust Indoor Location Estimation of Stationary and Mobile Users
, 2004
"... We present algorithms for estimating the location of stationary and mobile users based on heterogeneous indoor RF technologies. We propose two location algorithms, Selective Fusion Location Estimation (SELFLOC) and Region of Confidence (RoC), which can be used in conjunction with classical location ..."

The SELFLOC algorithm infers the user location by selectively fusing location information from multiple wireless technologies and/or multiple classical location algorithms in a theoretically optimal manner. The Ro

SOCIAL STRUCTURE BASED ROUTING OF INTERMITTENTLY CONNECTED NETWORK USING CONTACT INFORMATION
"... Social structure refers to relatively enduring patterns of behavior and relationship within social systems. In this paper, we propose a novel routing scheme, which takes advantage of the social structure of underlying ‘owners’ and their mobile devices in intermittently connected networks. We focus o ..."
