Intermittently connected opportunistic networks experience frequent disconnections and shorter contact durations. Therefore routing of messages towards their destinations needs to be handled from various points of view. Predictability and connectedness are two information which can be determined by participating mobile nodes of an opportunistic content distribution network using their past contacts. Epidemic or probabilistic routing protocols do not fully utilize these information to route messages towards their destinations. In this paper we describe the routing algorithm, implementation details, experiment design and the performance validation of a new, adaptive routing protocol which utilizes the predictability and connectedness information to route messages efficiently. Simulation based comparative studies show that the proposed routing protocol outperforms existing Epidemic and probabilistic routing protocols in delivering messages.

The dynamic business environment today has created immense pressure on the delivery of IT projects. Traditional methods of managing projects are no longer applicable and effective to manage certain IT projects as they are unable to cope with the rapid organizational and business level changes. Agile project management has caught the attention of many project managers as a means of facing these challenges and to overcome the limitations of managing IT projects. This study reports the results of an adaptation analysis done on Agile Project Management in managing IT projects in Sri Lanka. The awareness level of agile project management and what factors affect the awareness are discussed in this study. The agile project management implementation challenges and recommendations discussed in this study will help Sri Lankan organizations to successfully adopt agile project management.

Future wireless communication systems like 3GPP Long Term Evolution are required to support extreme high speed packet data transmission. Due to the limitation of available spectrum resource, high spectrum efficiency technologies are needed to be explored for different OSI layers. Over last decades, many technologies have been investigated to achieve this target. Multiple-input multiple-output (MIMO) system and channel-aware scheduling are two promising schemes proposed for that achievement. In this paper, we investigate the impact of MIMO and scheduling in the increasing of the system throughput of next generation mobile wireless systems when transmitting on different channels for several transmission modes. A cross-layer approach in resource allocation and scheduling schemes is emphasized.

One of the most promising and leading machine translation strategies would be Statistical Translation Approach. Being pertinent even to structurally dissimilar language pairs, it has confirmed its suitability for large text translation. Rising demand is present for automatic translation between Sinhala and Tamil for quite a lot of decades. Statistical approach is the best preference to resolve the unavailability of a machine translation tool for the languages concerned. Because of language similarity, statistical approach could thrive agreeably, exclusive of more concern on linguistic knowledge. A basic translation system has been modelled and implemented in this research, with the preparation of parallel corpora from parliament order papers. This paper demonstrates only the preliminary system runs of the research, devoid of various parameter refinements and actual design and evaluation strategies. Language Model, Translation Model and Decoder Configurations are done consistent with recent literature. To facilitate the improvement of output quality, MERT technique is integrated to tune the decoder. To stay away from sole dependence on BLEU, two other automatic metrics namely TER and NIST are utilised for the evaluation in different aspects. In addition, directions to future research are also recognized and specified for the refinements of this system.

Cloud computing is the provision of providing dynamically scalable and often virtualized resources as a service over the Internet. It is a model for enabling convenient, on-demand network access to a shared pool of configurable computing resources that can be rapidly provisioned and released with minimal management effort and cloud provider interaction. Enterprises across the world are moving their business infrastructure from on-premise to the cloud. The lack of reliability and inter-portability in the current cloud deployment architecture makes this transition much slower than expected. The most of existing cloud providers are using 2-tiered cloud deployment architecture. This paper presents a 3-tiered cloud deployment architecture which ensures the improved reliability and inter-portability in the cloud environment.

Virtual learning environments have been increasingly utilized in the domain of eLearning recently. Virtual worlds such as SecondLife and OpenSimulator have opened up great opportunities in this front. The major issue with virtual worlds with respect to education is lack of models that consistently describe the entire learning process. Most of the prior work was focused on building tools to extend real world learning tasks to virtual worlds rather than building virtual world based learning models which consistently describe the virtual world based learning itself. The ongoing work presented here is focused on filling the void in virtual world based learning models.

The amount of visual information available in digital format has grown exponentially in recent years due to the wide availability of digital equipments, changes in the way people socially interact by setting up community web pages, wide spread use of the Internet in all types of personal and business activities, pay-after-trial services of digital multimedia and developments in high speed transmission of digital images with high reliability. However, the wide accessibility of the Internet and its connected hosts and availability of technology to capture network traffic or penetrate hosts have made digital images vulnerable to unauthorized access while in storage and during transmission over a network. Hence users of the Internet and application that use or process digital images need to address security issues to protect commercial value of images and also ensure user privacy and other issues. The objective of the research presented in this paper focused on proposing an image encryption technique which is capable of encrypting an image effectively and securely with a predefined visibility level. The stipulated objective is achieved by employing 2D chaotic map called the Kaplan-Yorke map.

With the enormous growth of the World Wide Web, search engines play a critical role in retrieving information from the borderless Web. Although many search engines are available for the major languages, but they are not much proficient for the less computerized languages including Myanmar. The main reason is that those search engines are not considering the specific features of those languages. A search engine which is capable of searching the Web documents written in those languages is highly needed, especially when more and more Web sites are coming up with localized content in multiple languages. In this study, the design and the architecture of language specific search engine for Myanmar language is proposed. The main features of the system are, (1) it can search the multiple encodings of the Myanmar Web page, (2) it is designed to comply with the specific features of the Myanmar language. Finally the experiment has been done to prove whether it meets the design requirements.

The radical growth of internet & cybercrime during the last few years has forced us to think about how to improve information security efficiently during communication. Protecting the information during communication via the internet is the major challenge against eavesdropper. Encryption is a widely used technique to ensure secure communication; however, sending encrypted messages often draws an eavesdropper's attention. Steganography is a method of writing secret messages in a way that nobody, except for the sender and the recipient, suspects the existence of a hidden message. In this paper a new steganographic technique is proposed to transmit concealed messages in multi-language or combination of languages, which can be represented in Unicode. Use of inter-character spacing technique is proposed as the steganographic technique and a prototype implementation has been done with Rich Text Format (RTF) documents. An additional optimized compression technique is also proposed with enhanced user defined codes, to support Unicode language. Another advantage is that the secret message (hidden) can be in a different language than which is transmitted through the communication channel.
