Reducing energy consumption in the Internet has become an increasingly important goal recently. Previous work on reducing energy consumption has primarily looked at either changing link rates or putting interfaces to sleep. Due to the unpredictable nature of traffic, the energy savings achieved have been modest, do not scale, and incur losses and delay. This article proposes a different approach to...
The objective of the paper is to analyze team dynamics, behavior and its impact to the performance and movement of a team under different paradigms. This paper attempts to study and analyze the team behavior in software companies by using a soft computing technique - fuzzy logic. The argument discussed in this paper is that the success of a team is based on the collective behavior of its team members...
In the BitTorrent peer-to-peer file sharing protocol, it is observed that when a group of peers known to each other (due to geographical proximity or otherwise) are aiming for the same file, it is downloaded by a single peer and then shared within the group or it is downloaded individually. This is an inefficient approach as the fidelity rests on one peer or all peers (promoting redundancy), thus...
Performance and availability are of critical importance when Internet services are integrated into emergency response management. Poor performance or service failure can result in severe economic, social or environmental cost. This paper presents Whirlwind, a software architecture that includes primitives for overload management and fault tolerance. A Whirlwind service is composed of a collection...
The emergence of e-commerce has created new financial needs that in many cases cannot be effectively fulfilled by the traditional payment systems. Recognizing this, virtually all interested parties are exploring various types of electronic payment system and issues surrounding electronic payment system and digital currency. Broadly electronic payment systems can be classified into four categories:...
Internet based enterprise level collaboration tools enable organizations to make decisions faster and more accurately with less effort. However, these tools provide limited real-time group collaboration within and across organizations. Multicast protocols were developed to provide efficient group communication. This paper proposes a novel IP multicast network layer filter architecture that provides...
An open domain question answering system is one of the emerging information retrieval systems available on the World Wide Web that is becoming popular day by day to get succinct and relevant answers in response of users' questions. The validation of the correctness of the answer is an important issue in the field of question answering. In this paper, we are proposing a World Wide Web based solution...
Routers are normally manually configured with IPv6 prefixes in the traditional network. However, due to some of the MANET inherent characteristics such as multi-hop, ad hoc and mobility, manual configuration of prefixes is not desirable and practical. Rather than relying on a dedicated server, a distributed way of allocation is more suitable in the MANET environment. In this paper, we propose a distributed...
In order to communicate among themselves and with the devices on the Internet, a Mobile Ad-hoc NETwork (MANET) node needs to configure its interface(s) with IP address(es). MANET is a multi-hop network often consisting of mobile devices such as mobile phones, PDAs, laptops with wireless interface(s). Due to some of the MANET inherent characteristics such as mobility, multi-hop and ad hoc, manual configuration...
The security risks of using standard personal computers and operating systems for confidential transactions such as Internet banking are well-known. This is one reason for the interest in the mobile phone/ handset as a Personal Trusted Device (PTD). However, mobile phones have other shortcomings, for example the constraints of working with a small screen. This paper explores the use of a dedicated...
We consider the question "What if we could redesign the Internet, how would we do it?" The preliminary proposal discussed in this paper is based on two observations - today, and in the future, wireless access by users will be the predominant mode of communication and communication typically follows a group-pattern where groups of people and/or entities engage in a specific communication...
Different mechanisms have been proposed to integrate MANETs into the Internet. Most of them assume the presence of a dedicated entity acting as the Internet Gateway. This characteristic prevents MANET from operating in scenarios prepared for one-hop Wireless LAN where a Gateway is not pre-existing or configured. One possible solution to suppress this restriction is described in the mobile multi-gateway...
WiMax technology offers the possibility for many Indians to wirelessly connect to high-speed Internet without the need for DSL links and cable modems. While many businesses recognize the potential, the Indian government has been slow to allocate spectrum for WiMax. As an alternative, vendors are looking at the subgigahertz band subject to ratification by the WiMax Forum, a consortium of WiMax equipment...
