Human mobility models and opportunistic communications system design.

چکیده
In this paper, we seek to improve understanding of the structure of human mobility, with a view to using this for designing algorithms for the dissemination of data among mobile users. We analyse community structures and node centrality from the human mobility traces and use these two metrics to design efficient forwarding algorithms in terms of delivery ratio and delivery cost for mobile networks. This is the first empirical study of community and centrality using real human mobility datasets.

Connectivity Management for Opportunistic Communications in PSN
Opportunistic communications through Pocket Switched Networks (PSN) is a communication paradigm which aims to exploit contact opportunities between mobile devices and human mobility to transfer data in a peer-to-peer fashion. Building real PSN systems is challenging: mobile devices have resource limitations, network interfaces and protocols do not readily support ad hoc communications, and fina...
متن کاملOpportunistic Neighbour Prediction Using an Artificial Neural Network
Device mobility is an issue that affects both MANETs and opportunistic networks. While the former employs conventional routing techniques with some element of mobility management, opportunistic networking protocols often use mobility as a means of delivering messages in intermittently connected networks. If nodes are able to determine the future locations of other nodes with reasonable accuracy...
متن کاملGame Theory in Wireless Ad- hoc Opportunistic Radios
In this chapter we explain how we use game theory application in wireless communication ad-hoc network. The application of mathematical analysis to the study of wireless communication ad hoc networks has met with limited success due to the complexity of mobility, traffic models and the dynamic topology. A scenario based UMTS TDD opportunistic cellular system with an ad hoc behaviour that operat...
متن کاملPower law and exponential decay of inter contact times between mobile devices1
We examine the fundamental properties that determine the basic performance metrics for opportunistic communications. We first consider the distribution of inter-contact times between mobile devices. Using a diverse set of measured mobility traces, we find as an invariant property that there is a characteristic time, order of half a day, beyond which the distribution decays exponentially. Up to ...
متن کاملRethinking Network Mobility in Pervasive Markets: Model and Trust
With recent advances of wireless ad hoc networking, especially opportunistic forwarding and cognitive radio, there is an increasing concern that existing mobility models are insufficient to represent network mobility in real world settings. In this paper, we discuss our proposal for a more realistic mobility model which captures key features of human movements in pervasive markets. Our findings...
