This document discusses the system architecture of location-based services (LBS) based on spatial information integration. It introduces the basic components of an LBS system including the client, network, and server. A five-level hierarchical architecture is proposed consisting of a central data network, positioning parameters meaning level, positioning computation level, positioning coordination level, and application level. Ten primary functions of an LBS system are analyzed such as inverse geographical coding, neighborhood query, and real-time information distribution. Finally, an application case of LBS using the MapXtreme platform is described.

IDP: A Privacy Provisioning Framework for TIP Attributes in Trusted Third Par...Rida Qayyum
Location-Based Services (LBS) System is rapidly growing due to radio communication services with wireless mobile devices having a positioning component in it. LBS System offers location-based services by knowing the actual user position. A mobile user uses LBS to access services relevant to their locations. In order to provide Point of Interest (POI), LBS confronts numerous privacy related challenges in three different formats including Non-Trusted Third Party (NTTP), Trusted Third Party (TTP), and Mobile Peer-to-Peer (P2P). The current study emphasized the TTP based LBS system where the Location server does not provide full privacy to mobile users. In TTP based LBS system, a user’s privacy is concerned with personal identity, location information, and time information. In order to accomplish privacy under these concerns, state-of-the-art existing mechanisms have been reviewed. Hence, the aim to provide a promising roadmap to research and development communities for the right selection of privacy approach has achieved by conducting a comparative survey of the TTP based approaches. Leading to these privacy attributes, the current study addressed the privacy challenge by proposing a new privacy protection model named “Improved Dummy Position” (IDP) that protects TIP (Time, Identity, and Position) attributes under TTP LBS System. In order to validate the privacy level, a comparative analysis has been conducted by implementing the proposed IDP model in the simulation tool, Riverbed Modeler academic edition. The different scenarios of changing query transferring rate evaluate the performance of the proposed model. Simulation results demonstrate that our IDP could be considered as a promising model to protect user’s TIP attributes in a TTP based LBS system due to better performance and improved privacy level. Further, the proposed model extensively compared with the existing work.
AN ARCHITECTURAL FRAMEWORK FOR DELIVERING SIP-AS MULTIMEDIA SERVICES BASED ON...ijngnjournal
This paper proposes a new scalable service-oriented architecture based on Open Service Gateway Initiative (OSGI) technology. A key part of this architecture is its SIP application as a service (SIP-AS). It relies on IMS core network supported by multi agents components implemented using Java Agent DEvelopment (JADE) platform. As a proof of concept, a real testbed/prototype has been developed to validate our approach. The validation process consisted of two phases: (i) configuration of the JADE/OSGi SIP-AS architecture to provide a televoting service and (ii) characterization and analysis of jitter, packet loss, load capacity and CPU utilization of the implemented architecture. Results demonstrate that this televoting service scales up and out enabling the elasticity of the architecture on the processing of concurrent calls and dynamic load balancing.
Reducing Latency in African NRENS Using Performance-Based LISP/SDN Traffic En...csandit
Active topology measurements on the African Internet have showed that over 75% of the intraAfrica
traffic destined for Africa's National Research and Education Net- works (NRENs) uses
intercontinental links, resulting in high latencies and data transmission costs. The goal of this
work is to investigate how latency-based path selection using Locator/Identifier Separation
Protocol (LISP) and Software Defined Networking (SDN) in NRENs can be used to reduce
inter-NREN latencies. We present aspects of an experimental prototype implementation for realtime
topology probes to discover lower-latency remote gateways and dynamic configuration of
end-to-end Internet paths. Simulation results indicate that ranking remote ingress gateways, and
dynamic configuration of end-to-end paths between gateways can lower the average latency for
inter-NREN traffic exchange.
Dynamic multiagent method to avoid duplicated information at intersections in...TELKOMNIKA JOURNAL
Vehicular ad hoc networks (VANETs) allow vehicles to contact one another to provide safety and comfort applications. However, mobility is a great challenge in VANETs. High vehicle speed causes topological changes that result in unstable networks. Therefore, most previous studies focused on using clustering techniques in roads to reduce the effect of vehicle mobility and enhance network stability. Vehicles stop moving at intersections, and their mobility does not impact clustering. However, none of previous studies discussed the impact of vehicle stopping at intersections on base stations (BSs). Vehicles that have stopped moving at intersections continue to send the same information to BSs, which causes duplicated information. Hence, this study proposes a new method named dynamic multiagent (DMA) to filter cluster information and prevent duplicated information from being sent to BSs at intersections. The performance of the proposed method was evaluated through simulations during the use of DMA and without-DMA (W-DMA) methods based on real data collected from 10 intersections in Batu Pahat City, Johor, Malaysia. Overall, the proposed DMA method results in a considerable reduction in duplicated information at intersections, with an average percentage of 81% from the W-DMA method.
Cooperative Data Sharing with Security in Vehicular Ad-Hoc Networkscsandit
Vehicles download the data when passing through a drive through the road (RSU) and then share the data after travelling outside the coverage of RSU.A key issue of downloading
cooperative data is how effectively data is shared among them self. Developing an application layer data exchange protocol for the coordination of vehicles to exchange data according to
their geographic locations. Coordinated sharing can avoid medium access control (MAC) layer
collisions and the hidden terminal effect can be avoided in the multi-hop transmission. A salient
feature of the application layer data exchange protocol, in the voluntary services, Vehicles purchase the requested data from service provider via RSUs. In this project, we propose a
cooperative data sharing with secure framework for voluntary services in special vehicles networks (VANETs). We also concentrate on security in the process of downloading data and
sharing. Applicants to ensure exclusive access to data applied and security of the vehicles

Traffic Control System by Incorporating Message Forwarding ApproachCSCJournals
During the last few years, continuous progresses in wireless communications have opened new research fields in computer networking, aimed at extending data networks connectivity to environments where wired solutions are impracticable. Among these, vehicular traffic is attracting a growing attention from both academia and industry, due to the amount and importance of related distributive applications to mobile entertainment. VANETs are self-organized networks built up from moving vehicles, and are part of the broader class of MANETs. Because of these peculiar characteristics, VANETs require new networking techniques, whose feasibility and performance are usually tested by means of simulation. In order to meet performance goals, it is widely agreed that VANETs must rely heavily on node-to-node communication. In VANET, each vehicle acts as a node and communicates with other vehicles within the range or communicates with base stations. The main idea is to deploy a wireless communication network that has a capability of sending and receiving messages between transmitter and mobile devices in the particular network. Results can be shown using an effective VEINS Simulator. This Simulator can produce detailed vehicular movement traces and can simulate different traffic conditions through fully customizable scenarios. The Framework is expected to be employed using such simulator that makes use of traffic modulator, network simulator and coupling module that integrates the traffic and network.

In the recent years, advances in Vehicular networks have attracted special attraction of researchers. Lately two types of applications have gain popularity: Road safety and Driving comfort. Reliable data transformation in the city environment is hard to accomplish due to presence of noise and obstacles. In
addition transient or permanent faults of vehicles or roadside routers (road components) are unavoidable, so we need a fault tolerant algorithm to overcome such failures. Although utilizing faulttolerant techniques cause to more efficiency and reliability in service discovery for vehicle networks, there are many few service discovery algorithms that have considered fault- tolerant techniques. In this paper we have improved one of these algorithms which is named Fault-Tolerant Location-Based
Vehicular Service Discovery Protocol (FLocVSD) in order to being more reliable.

Vehicular Ad-hoc network (VANET) is one of the emerging technologies for research community to get various research challenges to construct secured framework for autonomous vehicular communication. The prime concern of this technology is to provide efficient data communication among registered vehicle nodes. The several research ideas are implemented practically to improve overall communication in VANETs by considering security and privacy as major aspects of VANETs. Several mechanisms have been implemented using cryptography algorithms and methodologies. However, these mechanisms provide a solution only for some restricted environments and to limited security threats. Hence, the proposed novel mechanism has been introduced, implemented and tested using key management technique. It provides secured network environment for VANET and its components. Later, this mechanism provides security for data packets of emergency messages using cryptography mechanism. Hence, the proposed novel mechanism is named Group Key Management & Cryptography Schemes (GKMC). The experimental analysis shows significant improvements in the network performance to provide security and privacy for emergency messages. This GKMC mechanism will help the VANET user’s to perform secured emergency message communication in network environment.

Intelligent GIS-Based Road Accident Analysis and Real-Time Monitoring Automat...CSCJournals
It has been a big concern for many people and government to reduce the amount of road accident specially in Malaysia since it could be a big threat to this country. Malaysian government has spent millions of money in order to reduce the number of accident occurrence through several modes of campaign. Unfortunately, from years to years the number keeps increasing. The lack of a comprehensive accident recording and analysis system in Malaysia can be effective in these kinds of problems. By making use of IRAS (Intelligent Road Accident System), the police would be control and manage whole accident events as a real-time monitoring system. This system exploits WiMAX and GPRS communications to connect to the server for transfer the specific data to the data center. This system can be used for a comprehensive intelligent GIS-based solution for accident analysis and management. The system is developed based on object and aspect oriented software design such as .NET technology.
LIGHTWEIGHT MOBILE WEB SERVICE PROVISIONING FOR THE INTERNET OF THINGS MEDIATIONijujournal
Emerging sensor-embedded smartphones motivated the mobile Internet of Things research. With the integrated embedded hardware and software sensor components, and mobile network technologies, smartphones are capable of providing various environmental context information via embedded mobile device-hosted Web services (MWS). MWS enhances the capability of various mobile sensing applications such as mobile crowd sensing, real time mobile health monitoring, mobile social network in proximity and so on. Although recent smartphones are quite capable in terms of mobile data transmission speed and computation power, the frequent usage of high
performance multi-core mobile CPU and the high speed 3G/4G mobile Internet data transmission will quickly drain the battery power of the mobile device. Although numerous previous researchers have tried to overcome the resource intensive issues in mobile embedded service provisioning domain, most of the efforts were constrained because of the underlying resource intensive technologies. This paper presents a lightweight mobile Web service provisioning framework for mobile sensing which utilises the protocols that were designed for constrained Internet of Things environment. The prototype experimental results show that the proposed framework can provide higher throughput and less resource consumption than the traditional mobile Web service frameworks.

Mobility Management Scheme for Mobile Communication Systems. A Reviewiosrjce
An intelligent mobility management scheme for mobile communication systems was studied. From
the result obtained, it was discovered that mobile to mobile call setup times showed a better performance as
compared to fixed network to mobile call setup and mobile to fixed call setup times. Moreover, increasing the
number of location areas within the switch does not affect inter-MSC handover and location updates since the
size of the switch coverage area remains the same. And when the location areas within the switch is increased,
intra-MSC location updates and handover also increases. Finally, user mobility directly affects the signaling
traffic for handover, location management, radio resource allocation and routing.

Location privacy in Location Based Services (LBS) is the capability to protect the connection between user’s identity, uncertainty sources, servers and database, thereby restraining an impending attacker from conveniently linking users of LBS to convinced locations. Smart Phones have become most important gadget for maintaining the daily activities, highly interconnected urban population is also increasingly dependent on these gadgets to regulate and schedule their daily lives. These applications often depend on current location of user or a class of user. Use of Smart Mapping technology is also increasing in large area; this system provides an easy attainable online platform that can be used for accessing many services. This survey paper projects the privacy-preserving algorithm to find the most favorable meeting location for a class of users. GSM calculates the location of all users.

Epistemic Interaction - tuning interfaces to provide information for AI supportAlan Dix
Paper presented at SYNERGY workshop at AVI 2024, Genoa, Italy. 3rd June 2024
https://alandix.com/academic/papers/synergy2024-epistemic/
As machine learning integrates deeper into human-computer interactions, the concept of epistemic interaction emerges, aiming to refine these interactions to enhance system adaptability. This approach encourages minor, intentional adjustments in user behaviour to enrich the data available for system learning. This paper introduces epistemic interaction within the context of human-system communication, illustrating how deliberate interaction design can improve system understanding and adaptation.

is introduced in this paper. It is composed of client, network and
server. According to the work flow of LBS system, LBS service
hierarchical architecture is elaborated on based spatial
information Integration. Five levels architecture is described in
detail and around 10 primary functions are analyzed also.
Finally the application mode of LBS is proposed.
Index Terms—Location Based Service(LBS), positioning, spatial
information.
I. LBS AND ITS WORK FLOW
LBS is personalized service based on the position and
location. It utilizes GIS technology, GPS technology, network
communication technology to obtain spatial positioning
information and transmit to server side for processing. The
work flow of LBS is shown as in figure 1[1,2]. Where mobile

users need information service or the management center
needs to track them, the embedded positioning device, i.e,
GPS provides current positioning information and transmits to
the center. The service requirements are analyzed by the GPS
central GIS server to get result, which is transmitted to the
mobile users.
LBS generally includes two process. One is to collect the
position, the other is to provide service according to user
requirement. To the consumers, it is probably to show the
nearest point of interest such as restaurant or the destination
city of the dealer.
II. COMPONENTS OF LBS
LBS system is mainly composed of mobile terminal,
wireless communication and application server. Figure 2
shows the basic components of LBS system[3]. There is two
working mode, active and passive in LBS system. Active LBS
system is mainly for mobile user to provide information
service. Passive LBS system is for enterprise customer to
manage fleet and decision making.
Mobile terminal is the positioning information serves and
the output terminal of system application. It can be hap phone,
laptop PC or Personal Digital Assistant, and so on.. Wireless
communication is the only way to provide transmission
channel for the mobile user and the system management center.
The application server process the service request by GIS
platform and send the information to mobile user.
Currently, public communication network, i.e,
GSM/GPRS/3G can be used to transmit high speed data
service, including media[4].
The positioning technology used in LBS includes
wireless communication cellular position and Assistant
GPS(A-GPS) cellular location technology is based on
the cellular communication system.
According to FCC legislation, American wireless
operators have to provide location service with 125m
precision and 67% probability. The positioning method
is composed of Angle of Arrival(AOA). Enhanced
observed Time Difference (E--OTD), CELL—ID:
Time Difference of Arrival(TDOA) and so on. A-GPS
is based on the communication of GPS receiver and
cellular device to provide more available positioning
information[5-7].
In application server side, the geographical data
and attributes data are managed by GIS platform. It provides
spatial query and analysis function at the point of interest and
it can also provide decision support for enterprise customer.
GIS can be thought as the center of LBS system, where the
organization mode and working efficiency directly influence
the quality of LBS.
III. LBS HIERARCHICAL ARCHITECTURE AND FUNCTIONS
A. Hierarchical
The LBS hierarchical architecture is shown a s in figure 3.
Five levels are included in the proposed architecture . The first
level is the central data network for basic data transmission.
The second level is positioning parameters meaning level. Its
function is providing precise positioning by
E—OTD/TDOA/AOA technologies with the canceling of
various interference. The third level is positioning
computation level, which is the crucial and hot part in recent

communication. For example, MAP/SMPP protocol provides the
exchanges between central data network and positioning
platform. MLP/XML can be used as communication
mechanism for application level and positioning platform.
Each level is also the integration of different
sub-levels. And each level can be implemented by one or
several entities[8-9].
