Wireless communication remains to be the most efficient way of providing access to information to users in developing economies. We are interested in Delay-Tolerant Networks (DTNs) for distributing multimedia content to micro-entrepreneurs in under-served rural areas of South Africa. In our project, public commuter buses carrying WLAN-enabled devices (mobile infostations) that provide DTN connectivity...
Mobility plays a key role in the forwarding of data in delay-tolerant mobile ad hoc networks, as it is mobility that gives rise to local connection opportunities. Different patterns of mobility may give rise to different opportunity for communication, and different protocols may be more effective in particular situations. It is thus becoming increasingly important to understand user mobility patterns...
Mobile technology is already playing an important role in the economic and social empowerment of rural communities in developing regions. However, rural areas often suffer from slow and unreliable network infrastructures. This limits access to content and services that may promote economic development. Focusing on under-served areas in rural developing regions, we aim to explore how ICT systems for...
Simulations of mobile ad-hoc, sensor, and mesh networks strongly rely on mobility models because they have a major influence on the performance of protocols. Results obtained with an unrealistic model may not reflect the true performance of protocols, applications and algorithms in real environments. In this paper, we present a mobility model for shopping mall environments based on real traces. Such...
In this paper, we seek to improve understanding of human mobility patterns in environments having definite and highly organized structure, such as shopping malls. We present a method to identify individuals expressing different mobility patterns. Besides, to understand better the role of groups of message carriers expressing different mobility patterns, we performed simulations of a derivative of...
