“…It is also worth asking if we can find the max-min fair allocation without running the algorithm. It is quite straightforward and can posed as a convex program [18], with the interface and usage preferences used to indicate constraints on the system.…”

“…Our implementation, in Linux 3.0.0-17, follows the architecture illustrated in Figure 3. This custom bridge allows us to steer individual packets to whichever interface the scheduling algorithm chooses, while being transparent for the applications [20]. This is done by presenting the applications with a virtual interface with an arbitrarily chosen address and then rewriting the packet headers appropriately before transmission.…”

“…MultiNet [2] virtualizes a single wireless device into multiple virtual interfaces, allowing more networks to be accessible over the same hardware. MPTCP [15] provides an end-toend reliable protocol for multiple interfaces; Serval [9] proposes a service access layer that allows services to use multiple interfaces; and [20] exposes an efficient software switch to manage multiple interfaces. These approaches focus on consolidating access to multiple interfaces allowing applica- tions to use them through a simple abstraction.…”

Now that our smartphones have multiple interfaces (WiFi, 3G, 4G, etc.), we have preferences for which interfaces an application may use. We may prefer to stream video over WiFi because it is fast, but VoIP over 3G because it gives continued connectivity. We also have relative preferences, such as giving Netflix twice as much capacity as Dropbox. This means our mobile devices need to schedule packets in keeping with our preferences while making use of all the capacity available. This is the natural domain of fair queuing, and this paper is about the design of a packet scheduler to meet these requirements. We show that traditional fair queueing schedulers cannot take into account a user's preferences for some interfaces over others. We present a novel packet scheduler called miDRR that meets our needs by generalizing DRR for multiple interfaces. We demonstrate a prototype running in Linux and show that it works correctly and can easily run at the speeds we need.

This connection is used by almost every single application on the device including web browsers, email clients, messaging applications, etc. Unfortunately, the cellular networks on our smartphones are not perfect and do not always have cellular signal.Our devices often lose Internet connection when users are on the go and traveling.This thesis presents a novel in-depth implementation and evaluation of what we can achieve when a user loses network connectivity. BleHttp, a library for Android, was developed that uses Bluetooth Low Energy to connect to other devices using a different carrier within close proximity of each other and make HTTP requests. In our results, we saw 100% success rates on HTTP requests with connected devices on a good connection. Average round trip times were tested to be as low as 1.5 seconds.iv ACKNOWLEDGMENTS I am extremely grateful for the incredible support system that has been with me throughout this entire process. Thank you so much for all the support:• My parents, Norman and Cindy.• My sister, Helen.

The exponential growth of the number of multihomed mobile devices is changing the way how we can connect to the Internet. Our mobile devices are demanding for more network resources, in terms of traffic volume and QoS requirements. Unfortunately, it is very hard to a multihomed device to be simultaneously connected to the network through multiple links. The current work enhances the network access of multihomed devices agnostically to the deployed access technologies. This enhancement is achieved by using simultaneously all of the mobile devices interfaces, and by routing each individual data flow through the most convenient access technology. The proposed solution is only deployed at the network side and it extends Proxy Mobile IPv6 with flow mobility in a completely transparent way to mobile nodes. In fact, it gives particular attention to the handover mechanisms, by improving the detection and attachment of nodes in the network, with the inclusion of the IEEE 802.21 standard in the solution. This provides the necessary implementation and integration details to extend a network topology with femtocell devices. Each femtocell is equipped with various network interfaces supporting a diverse set of access technologies. There is also a decision entity that manages individually each data flow according to its QoS / QoE requisites. The proposed solution has been developed and extensively tested with a real prototype. Evaluation results evidence that the overhead for using the solution is negligible as compared to the offered advantages such as: the support of flow mobility, the fulfil of VoIP functional requisites, the session continuity in spite of flows mobility, its low overhead, its high scalability, and the complete transparency of the proposed solution to the user terminals.
