This thesis work is concerned with communication in large random wireless ad hoc networks. We mathematically model the wireless network as a collection of randomly located nodes, and explore how its performance scales as the network size increases. In particular, we study three important properties: broadcasting ability, rate of information exchange, and secret communication capability. In addition, we study connectivity properties of large random graphs in a more general context, where the graph does not necessarily represent a wireless communication network. Broadcasting, i.e., delivering a message from a single node to the entire network in a wireless ad hoc network …

An Innovative Approach Towards Applying Chaum Mixing To Sms, Matthew Patrick Rothmeyer
Graduate Theses and Dissertations
Currently there are few user-friendly applications for anonymous communication across multiple platforms, leaving data that is often both personal and private vulnerable to malicious activity. Mobile devices such as smartphones are prime candidates for such an application as they are pervasive and have standardized communication protocols. Through the application of mixing techniques, these devices can provide anonymity for groups of individuals numbering 30 to 40 members. In this work, a Chaum mix inspired, smartphone based network that uses the Short Message Service (SMS) is described first in theory and then in implementation. This system leverages both techniques used by current …
