Personal Cloud P2P

Small and medium sized businesses have lacked of good and automate backup system. Data storages are unreliable and tend to fail without any warning. Whereas, personal computers are already equipped with terabytes of hard drives. This is enormous space for personal or business use. Under normal working conditions, more than half of total storage space is not being used. It is scattered in all connected devices. This paper proposes pooling unused storage resources to create a personal private cloud. The process will be transparent to the users by having a reliable drive with an auto backup built in. The proposed system solution uses a replica-based model in which three sets of the same information would distribute and keep in three different nodes. All the participated nodes are peer-to-peer (P2P) and are decentralized. Therefore, private cloud system can support small or medium businesses as backup system or business sharing drives without adding any cost.

Distribution of 3G Services Among Rural Towns: Case Study of Bhutan

In developed countries, 3G services are common and usually provided by several private operators with almost 100 % coverage. However, the situation is quite different in most developing countries with majority of people are considered under poverty. In most of these countries, telecommunication services are provided by state enterprise which cannot only make profit but have to support people as well. Therefore, compromise must be made in order to serve people within acceptable profit. In this paper, the distribution of 3G services among rural towns are modeled and optimized by the famous linear programming. The proposed model considers both population coverage and expected income, which can be easily utilized by state telecommunication enterprise of any developing country. The example is made based on the case of three border towns of Bhutan. With flexible adjustment of parameters, the proposed technique provides tradeoff valued to investment.
