Wireless Local Area Network (WLAN) can provide high data-rate wireless multimedia applications to end users in a limited geographical area and has been widely deployed in recent years. For indoor WLAN systems, how to efficiently improve service coverage is a challenging problem. In this paper, we propose a coverage improvement scheme that can identify suitable Mobile Stations(MS) in good servic...

decentralization is the process of dispersing decision-making closer to the point of peripheral area, service or action. basically decentralized governance, if properly planned and implemented, offers important opportunities for enhanced human development. the studies about this issue in different countries show that most of the decentralizations have been implemented in european countries and ...

Background The Community Mine Continuation Agreement Middle (CMCA) and South Fly Health Program (the Health Program) is a partnership for improving health service delivery in remote Papua New Guinea (PNG). The Health Program is delivered by a private contractor working in partnership with existing health service providers to improve service delivery using existing government systems, where poss...

Dealing with service composition is an important and challenging issue of distributed systems. Existing works investigate mechanisms for analyzing and synthesizing a composition based on qualitative properties which characterize operations and/or messages choreography constraints. Apart from these qualitative properties, quantitative properties such as time related features are a crucial settin...

We have designed and implemented a Web service for location discovery (LODS) and a location-based printing service that uses LODS on a network with wireless LAN connectivity based on IEEE 802.11 that is typical to campuses and enterprises. The need for location management and location-based services is linked to the mobility of the users. While location discovery is already implemented in cellu...

We analyse the behaviour of data and streaming transmissions in wireless networks. We propose to use a modified access point with Quality of Service features. It is expected that the modification will improve transmission terms for multimedia streams.

the purpose of this paper is to analyze the utility operating radius and service on city parks in ardabil neighborhood, local, regional and urban level, to investigate the relationship between the distribution of these parks with water levels in the city of ardabil, including shorabil lake and balyqlv river and reviews for distribution park. the data and information used by documentary. to anal...

There is a growing need for quality of service (QoS) provisioning over 802.11 wireless local area networks. The 802.11e amendment addresses this need by allowing for traffic to be given different priority assignments. This can allow for QoS to be provided by service differentiation. In this paper we provide a simple throughput/delay analysis for p-persistent CSMA which can be used as an analysi...
