Cell therapy has the potential to impact the quality of life of suffering patients. Systemic infusion is a convenient method of cell delivery; however, the efficiency of engraftment presents a major challenge. It has been shown that modification of the cell surface with adhesion ligands is a viable approach to improve cell homing, yet current methods including genetic modification suffer potent...

The emergence of OpenFlow and Software Defined Networks brings new perspectives into how we design the next generation networks, where the number of base stations/access points as well as the devices per subscriber will be dramatically higher. In such dense environments, devices can communicate with each other directly and can attach to multiple base stations (or access points) for simultaneous...

Compared to their predecessors, the current generation handheld mobile devices possess higher processing power, increased memory and new multi-homing capabilities. These features combined with the widespread acceptance and use of these devices result in a situation where mobile devices are no longer merely data consumers, but also able to act as data producers. Nomadic mobile services make this...

Software-defined networking (SDN) promises to improve the programmability and flexibility of networks, but it may bring also new challenges that need to be explored. The purpose of this technical report is to assess how the deployment of the SDN controllers affects the overall availability of SDN. For this, we have varied the number, homing and location of SDN controllers. A two-level modelling...

In this paper I estimate theory-based structural models of two-sided markets with competing platforms. Given platforms’attributes and (two) prices, agents of each side decide which platforms to join. Platforms set prices to maximize the sum of profits that they earn from the two sides. There are two demand equations to be estimated, and both should be used in estimating platform markup due to c...

The user’s handoff is still an arguable issue that many mobile communication systems face, especially with the exploded growth of users and internet-based applications. There a critical need for adequate quality service (QoS) to meet stringent requirements. This paper aims study overall performance feasibility several QoS mechanisms single-homed multi-homed networks/nodes fluctuating resource a...

At the Transport Layer in Internet model, Transmission Control Protocol provide host-to-host connectivity. There are many other protocols under TCP like SCTP (Stream Control Transport Protocol) and DCCP (Datagram Congestion Control Protocol) which provides more features. DCCP is unreliable transport layer protocol designed to provide congestion control and suitable for time delivery of data. SC...
