This paper focuses on the use of CoAP as a means of connecting clouds of sensors & smart devices via mobile devices with users. We present an alternative to the hierarchical view on fog-computing by enabling device clouds to interact in a P2P fashion with smart device/sensor clouds. Using the IoT protocol CoAP we expose smart device/sensors and resources in the mobile cloud in a uniform manner...
Most enterprises today have their own Private Branch Exchange (PBX) systems that enable them to communicate on-premise and with the external or public switch telephone network. Companies that rely on heavy phone calls (especially, debt collectors) find the approach cost effective especially when automation techniques are introduced for auto dialing as a measure to reduce the number of employees who...
This work explores the design trends on Mobile Cloud Computing (MCC) and the recent shift to Ubiquitous Cloud Computing (UCC). The study shows that efficient architectures for the MCC and UCC systems can be deployed through the employment of techniques such as: Virtual Machine (VM) Architectures and Migration, Data, Services, Resource and Computation Offloading, Partitioning and Parallel Execution,...
Analytics-as-a-Service (AaaS) has become indispensable because it affords stakeholders to discover knowledge in Big Data. Previously, data stored in data warehouses follow some schema and standardization which leads to efficient data mining. However, the Big Data epoch has witnessed the rise of structured, semi-structured, and unstructured data, a trend that motivated enterprises to employ the NoSQL...
This paper presents a mobile application called MobiCrop that aids crop farmers in the application of pesticides. The requirement of the application is to have a monitoring station where updates are constantly being pushed to the farmers who are geographically dispersed. This requirement creates the need to deploy a mobile distributed architecture rather than a standalone app that has become the standard...
Mobile technology is increasingly being adopted in the agricultural space as a measure to assist farmers in decision. In this regard, the MobiCrop project was initiated by the researchers from the College of Agriculture at the University of Saskatchewan, Canada, and the Multi-Agent Distributed Mobile and Ubiquitous Computing (MADMUC) Lab. The aim of the project is to enable farmers to have mobile...
Cloud Computing [1,2] is a "utility computing model" (John McCarthy, 1961), that allows the purchase of virtualized hardware (Infrastructure as a Service, IaaS), software platforms (Platform as a Service, PaaS) or applications/functionality (Software as a Service, SaaS) in a pay-as-you-go manner, comparable to the metered purchase of electricity, gas or water. Seen in the past primarily...
The Digital Ecosystem (DE) paradigm is a holistic management/design/integration approach that is based on the notion of self-interested, self-managing, proactive and autonomous digital entities that evolve and self-organize. This in turn leads to the emergence of complex, self-organizing behaviours within a DE due to the evolving and highly dynamic interactions of its members. These interactions are...
Delivering TV services via internet protocols over high-speed connections is commonly referred to as IPTV (internet protocol television). Similar to the app-stores of smartphones, IPTV platforms enable the emergence of IPTV service ecologies in which 3rd party developers provide services to consumer that add value to the IPTV experience. A key issue in the IPTV ecosystem is the resilience of its services...
The Digital Ecosystem (DE) paradigm is a holistic management/design/integration approach that is based on the notion of self-interested, self-managing, proactive and autonomous digital entities that evolve and self-organize. While a DE can be realized using different technologies (e.g. P2P, Multi-Agent System) web-services is particularly well suited due to the similarity of underlying concepts. A...
Cloud providers, like Amazon, offer their data centers' computational and storage capacities for lease to paying customers. High electricity consumption, associated with running a data center, not only reflects on its carbon footprint, but also increases the costs of running the data center itself. This paper addresses the problem of maximizing the revenues of Cloud providers by trimming down their...
Mobile handsets (phones) are expected to increase from the current 4.5B (billion) subscriptions to over 6B in 2013 and thus dwarf the numbers of PCs (e.g. desktop, laptop, netbook, etc.) that are expected to rise from the current 1.1B to 2B in 2015. But more importantly, data transmission from and to mobile handsets is becoming and increasingly available and affordable. The dramatic improvements in...
