Motivation
 In ULOOP nodes are expected to move
 Carried by humans
 Gateways too…
 Roaming behavior is social (devices are carried by humans)
 Human roaming behavior has a sociological and anthropological relation
 By learning basic features of movement, the network operation can be improved
 Most relevant mobility models are known as “social mobility models”
 Social behavior impacts the way nodes in ULOOP move
 Trust management impacts roaming and mobility aspects

Which Aspects Relate to a Social Behavior?
 Social behavior of users roaming
 Roaming relates to carriers, and in ULOOP: carriers are humans
 The way that ULOOP nodes are grouped – centralitty

Examples of parameters that can be tracked
 Most visited locations (e.g. community, ULOOP gateway) by specific ULOOP
nodes
 Number of times a ULOOP gateway decides to hand over nodes to other gateway
 Pause time – stationary times
 Daily, weekly, monthly routine of ULOOP nodes concering their roaming behavior
 “Best” gateways or communities (according to the other mobility blocks)
 AND: Social behavior of users roaming
 Roaming relates to carriers, and in ULOOP: carriers are humans – B2
What can we Track?

Based on existing models, contribute with a scheme that can assist in estimating mobility of individuals
and of communities up to some extent, by modeling social aspects related to the roaming behavior of
users
To provide software functionality that assists both ULOOP nodes and gateways to learn about their
communities roaming behaviorFirst Phase
 Node keeps track of its own roaming behavior
 E.g. over periods of 1 week, visited
gateways and distances
 Node also gets information from its neighbors –
better definition of the roaming environment
 Provides an estimate of the next potential
destinations based on the learnt information
 Broadcasts, in the respective communities, such
information (passively, through beacon messages)
 If just a node: information just about itself
 If a gateway, table for all nodes in the community
Second Phase
 Builds on top of the previous one
 Cross-check information with the other blocks (RM,
TM)
 Send information to hotspots/neighbors about
user’s movement (parameters).

Define parameters to consider
 Both from a node and gateway perspective
 Define a basic scheme for the ULOOP mobility prediction module
 Based on current social mobility models
 Mobility Tracking Outcome
 Come up with metrics/algorithms capable of assisting in capturing mobility patterns of users,
relevant to assist the optimization of the network operation, in particular of ressource
maangement
 Mobility Prediction outcome
 Functionality that can optimize the network (anticipation)
 Contribution
 Provide a plugin to track mobility of users – ULOOP node and gateway
 Valiadte the plugin against a realistic setting (local testbeds)
