In this paper we improved the Dynamic Source Routing (DSR) protocol to Load Balanced DSR (LBDSR) protocol. We modified control messages in DSR in order to maintain remained energy of intermediate nodes. Routes discovered by these modified control messages, have a remained energy array field which shows total of remained battery power of all nodes in a route. Selecting a route is depending on le...

In this paper we present the performance analysis of an Energy Aware Multi-path Dynamic Source Routing protocol (EA-MPDSR). This protocol is based on the existing on-demand Dynamic Source Routing protocol (DSR). It is energy aware and uses a multi -path technique. EA-MPDSR reduces the energy consumed per received data bytes as well as prolongs the network lifetime which leads to improvement in ...

This paper presents a distributed speech recognition (DSR) system for information retrieval on mobile devices. The overall prototype system applies the state-of-the-art DSR technique and knowledge-based Information Retrieval (IR) processing for spoken question answering. A configurable DSR system is implemented on the basis of the ETSI-DSR advanced front-end and the SPHINX IV recognizer. Acoust...

Design science research (DSR) is a relatively new approach in information systems research. A fundamental tenet of DSR is that understanding comes from creating information technology artifacts. However, with an increasingly connected and globalized world, designing IT artifacts for a multicultural world is a challenge. The purpose of this paper, therefore, is to propose extending the DSR metho...

At present, the Information Systems (IS) community is debating the relevance of its research results. Design Science Research (DSR) is considered a promising approach to advance the scientific body of knowledge while, at the same time, resulting in research results of high practical utility. As a consequence, a number of guidelines and recommendations have been proposed to support the researche...

This work evaluates the performance of three well known routing protocols in mobile ad-hoc networks, namely Ad-hoc On demand Distance Vector Protocol (AODV), Dynamic Source Routing (DSR) and Temporally Ordered Routing Algorithm (TORA). Two scenarios were created using OPNET and extensive simulations were made on each scenario to evaluate the performance of the three protocols. Results were pres...

Design science is a fundamental research stream that contends its position in the information systems discipline. While ongoing debates address the relative importance of design science contributions in the information systems community, insights into the scientific impact of design science research (DSR) are missing and this lack of understanding arguably poses challenges to an informed discou...

In this introductory piece to the special issue on design science research (DSR) in information systems, the authors probe the past research in DSR, introduce the papers in the special issue, discuss their contributions to the field, and conclude the paper by highlighting some potential directions for future research. To provide a good overview of the research domain, the authors review the key...

. The Design Science Research Roadmap (DSR-Roadmap) [1] aims to give detailed methodological guidance to novice researchers in Information Systems (IS) DSR. Focus group evaluation, one phase of the overall study, of the evolving DSR-Roadmap revealed that a key difficulty faced by both novice and expert researchers in DSR, is abstracting design theory from design. This paper explores the extensi...

Parkinson's disease (PD) manifestations include motor symptoms and behavioural deficits that resemble schizophrenia negative symptoms. The N-methyl-D-aspartate subtype of glutamate receptor (NMDAR) represents a novel pharmacological target in PD. D-serine (DSR) allosterically modulates in-vivo NMDAR-mediated neurotransmission and has been shown to improve negative and antipsychotic drug-induced...
