Towards new methods for mobility data gathering: content, sources, incentives

Over the past decade, huge amounts of work has been done in mobile and opportunistic networking research. Unfortunately, much of this has had little impact as the results have not been applicable to reality, due to incorrect assumptions and models used in the design and evaluation of the systems. In this paper, we outline some of the problems of the assumptions of early research in the field, and provide a survey of some initial work that has started to take place to alleviate this through more realistic modelling and measurements of real systems. We do note that there is still much work to be done in this area, and then go on to identify some important properties of the network that must be studied further. We identify the types of data that are important to measure, and also give some guidelines on finding existing and potentially new sources for such data and incentivizing the holders of the data to share it

Information mobility: a new paradigm for wireless content dissemination

Content distribution networks are nowadays becoming a mature technology. Nevertheless, content delivery research in ad hoc networks has dealt with overlay applications, information querying and data broadcasting techniques. The aim of this paper is to explore and discuss content delivery in wireless ad hoc networks and to state challenges and reference models for this kind of networks. The concept of Information Mobility is introduced to point out that the contents are being stored in mobile nodes and that the contents move and replicate before being accessed. The network considered is a wireless ad hoc network with sparse connectivity and limited infrastructure support.Peer ReviewedPostprint (published version

THE EFFECT OF THE NUMBER OF MOBILE NODES ON VARYING SPEEDS OF MANETS

Abstract Mobile Ad hoc Networks (MANETs) are dynamic networks populated by mobile devices, or mobile nodes (MNs).TheMobile Nodes (MNs) arefreetomoveanywhere and at any time. The population of the nodes may have some influence on the mobility rate of the MNs.This paper presentssimulation results using MatLab software. The study investigates the influence of mobile nodes' parameters such as number of nodes on the nodes speedsand nodes distribution in a given area. The results have indicated thatthe number of mobile nodes have impact on the speeds of the nodes in a location
