|
| |
|
| Delay Tolerant Networks (DTN) are a particular family of networks characterized by high, unpredictable node mobility and consequently by the possible lack of a path between source and destination. To counterbalance the numerous drawbacks is the fact that these networks require little or no infrastructure and can act in a completely decentralized way. Many protocols have been proposed in the last 10 years. The student is required to present a general overview of DTN and in particular to investigate how DTN principles are used in hot researched fields, including Internet of Things (IoT), Vehicular Networks (VANETs), Emergency systems, Wireless Sensor Networks (WSN) and pervasive computing.

| |
|
| |
| Today, web services are increasingly being deployed in infrastructure-as-a-service (IaaS) clouds such as Amazon EC2, Windows Azure, and Rackspace. Hence, it is critical to understand the usage patterns and identifies ways in which cloud tenants could better leverage IaaS clouds.

| |
|
| |
| Crowdsourcing systems like Amazon's Mechanical Turk have emerged as an effective large-scale human-powered platform for performing tasks in domains such as image classification, data entry, recommendation, and proofreading. Since workers are low-paid (a few cents per task) and tasks performed are monotonous, the answers obtained are noisy and hence unreliable. To obtain reliable estimates, it is essential to utilize appropriate inference algorithms (e.g. Majority voting) coupled with structured redundancy through task assignment.

| |
|
| |
| Net neutrality refers to current state of the internet, where all data should be treated equally, without discrimination of specific flows or entities.
| |
| However, this state has recently been questioned by several providers and government authorities.
| |
| In this topic, the reasons and motivations for and against net neutrality should be investigated,
| |
| with a focus on the technical implementations and outcomes of an Internet, where neutrality is no longer given.

| |
|
| |
| The idea of Internet of Things -- or IoT -- is to interconnect uniquely identifiable embedded computing devices within the existing Internet infrastructure [http://en.wikipedia.org/wiki/Internet_of_Things].
| |
| Over 25 billion of such devices are expected to be connected within the IoT by 2020.
| |
| The IETF has recently released a protocol suite to enable communication between the devices.
| |
| In this topic, the most recent advances towards the IoT should be investigated to obtain a clear overview of where both research and industry are currently standing and whether or not the 2020 estimation is still valid.

| |
| Relevance is the most important factor to assure users’ satisfaction in search and the success of a search engine heavily depends on its performance on relevance. It has been observed that most of the dissatisfaction cases in relevance are due to term mismatch between queries and documents (e.g., query “ny times” does not match well with a document only containing “New York Times”), because term matching, i.e., the bag-of-words approach, still functions as the main mechanism of modern search engines.
