A key challenge of routing in delay tolerant networks (DTNs) is finding routes that have high
delivery rates and low end-to-end delays. When oracles are not available for future …

Mobile, delay-tolerant, ad hoc and pocket-switched networks may form an important part of
future ubiquitous computing environments. Understanding how to efficiently and effectively …

Future mobile sensing systems are being designed using 802.15. 4 low-power short-range
radios for a diverse set of devices from embedded mobile motes to sensor-enabled …

Traditionally, mobility in ad hoc networks was considered as a necessary evil that hinders
node communication. However, it has recently been recognised that mobility can be turned …

According to different kinds of connectivity, we can distinguish three types of mobile ad-hoc
networks: dense, sparse and clustered networks. This paper is about modeling mobility in …

We report that human walk patterns closely follow Levy walk patterns commonly observed in
animals such as monkeys, birds and jackals. Our study is based on about one thousand …

In this dissertation we describe the TRACE framework, which is a five-step procedure for the
environment-aware approach towards wireless mobile computer networks. As mobile …

This work explored mechanisms to asynchronously distribute video objects to intranet users.
The primary application driver was to disseminate lecture videos created by the instructor as …

In a real-life wireless network, the logical movements of mobile nodes are not purely
random. Movements of individual mobile nodes have intrinsic patterns determined by …

We address the challenge of providing low-cost, universal access of useful information to
people in different parts of the globe. We achieve this by following two strategies. First, we …
