Abstract:

Smartphones have facilitated tasks in private and work life for its users. In business, employees often should manage sensitive data that unauthorised people cannot access, so some user authentication is needed to perform. Besides the normal user authentication, some employers give the right to access to the sensitive data only if the employees stay in specific locations. That makes sense for those businesses that have various construction sites and offices that are not necessarily located in the same geographical region. In those companies, the employees must be able to perform their tasks fr

Abstract:

IEEE 802.11 is an economical and efficient standard that has been applied to vehicular networks. However, the long handoff latency of the standard handoff scheme for IEEE 802.11 has become an important issue for seamless roaming in vehicular environments, as more handoffs may be triggered due to the higher mobility of vehicles. This thesis presents a new and fast location-based handoff scheme particularly designed for vehicular environments. With the position and movement direction of a vehicle and the locations of the surrounding APs, our protocol is able to accurately predict several possibl

Abstract:

The importance of the data authentication has resulted in the science of the data protection. Interest in this knowledge has been growing due to the increase in privacy of the user's identity, especially after the widespread use of online transactions. Many security techniques are available to maintain the privacy of the user's identity. These include password, smart card or token and face recognition or finger print. But unfortunately, the possibility to duplicate the identity of a user is still possible. Recently, specialists used the user's physical location as a new factor in order to incr

Abstract:

One of the trickiest challenges introduced by cellular communications networks is mobility prediction for Location Based-Services (LBSs). Hence, an accurate and efficient mobility prediction technique is particularly needed for these networks. The mobility prediction technique incurs overheads on the transmission process. These overheads affect properties of the cellular communications network such as delay, denial of services, manual filtering and bandwidth. The main goal of this research is to enhance a mobility prediction scheme in cellular communications networks through three phases. Firs

Abstract:

The transmitting of video content over Vehicular Ad Hoc Networks (VANETs) faces a great number of challenges caused by strict QoS (Quality of Service) requirements and highly dynamic network topology. In order to tackle these challenges, multipath forwarding schemes can be regarded as potential solutions. However, route coupling effect and the path length growth severely impair the performance of multipath schemes. In this thesis, the current research status about video streaming over VANETs as well as multipath transmissions are reviewed. With the demand to discover a more suitable solution,

Abstract:

Location Management is defined as the process of tracking the position of a mobile terminal when it moves to its associated area within the network. This allows the network to detect the mobile user’s path for the purpose of call delivery. The location management schema in a public-LAN mobile network (IS-41 and GSM) is based on centralized two-tier database architecture. The root level is called the Home Location Register (HLR) and the second level is called the Visitor Location Register (VLR). The HLR permanently stores all the mobile users’ location information and the types of services subs

Node scheduling is one of the most effective techniques to maximize the lifetime of a wireless sensor network. It is the process of selecting a subset of nodes to monitor the sensor field on behalf of redundant nodes. At every round of the scheduling a small group of nodes are active while the rest of the sensor nodes are in sleep mode. In this thesis, we propose a novel node scheduling solution for wireless sensor networks. The main characteristic of our approach is its independence from location information as well as distance information. Moreover, it does not rely on unrealistic circular r

There are two approximation ratios are proved from PASS approximation, approximation ratio with the signature on optimal solution, and approximation ratio with the signature on feasible solution. We verify the both approximation ratio by implementing PASS approximation on maximum facility location problem.Besides, we use PASS approximation to analyze greedy-rate algorithm, and do experiments to compare approximation ratio and theoretical ratio. We have interest in the theoretical ratio prov

Abstract:

碩士<br>中華大學<br>電機工程學系(所)<br>97<br>In this thesis, a set of received signal strength (RSS) from access points (APs) is utilized to partition the desired area into at least six regions. The partition scheme is basically relative to the geometric setup of the access points. In other words, the testing points relative to different APs, not only distance but also geometric relation, will result in different set of RSS. However, RSSs always come with undesired noise which can be reduced its effect by applying the Kalman filter. During certain period of time, the average of signal strength of the set

In the tracking moving object of mechanism, Query Operation and Location Update Operation is the main operation, both Operations brought the main source of communication costs. In Moving Object Location Management, if we can reduce Query Operation and Location Update Operation bring communication costs, that for future research will be useful. However, the energy limited of sensors and object mobility increases a lot of difficulties for moving object

Abstract:

The population of India is 1.25 billion with 500 million of mobile subscriber. This huge change in mobile services resulted in crime hike, teenage kidnap, suicidal cases, and mobile thefts. It is only due to ease of carrying and flexibility in movement from one place to another. In a mobile network, mobile users travel at different velocity and different places. For mobile/network operator, it is useful to track each mobile user for its reference. It sometimes helps in investigational purpose, some lost and found reference. It is also useful to track exact location of the users using different

Abstract:

碩士<br>國立中央大學<br>通訊工程學系<br>102<br>Regarding indoor location estimation, many smart positioning techniques have been proposed and they could be classified into several categories. The fingerprinting is one of categories and its features are to build the indoor radio map during offline phase and to utilize the radio map to estimate the location during online phase. Creating indoor radio map is the most critical step, where the accuracy of location estimation depends on the distribution and number of reference points (RPs). Usually, the time required to collect received signal strengths (RSSs) is

Abstract:

碩士<br>國立臺灣大學<br>資訊網路與多媒體研究所<br>96<br>Sensor networks usually consist of thousands of resource-limited nodes and are deployed in a designated area without any fixed infrastructure. While the establishment of the pairwise keys between any pair of adjacent nodes to build a secure link remains the main concern in the design of key management protocols, malicious attacks aim at routing information, exhaust node’s resource, and compromised secrets can misdirect the data flow or denial the network service with relatively small effort. Many mission-critic sensor network applications demand an effectiv

碩士<br>國立交通大學<br>網路工程研究所<br>97<br>In this thesis, we proposed a Location Management and Smooth Handover Scheme with Proxy Table-based Routing Mechanisms for the 802.11s wireless mesh networks (WMNs). Unlike other WMNs, 802.11s WMNs adopts proxy-based layer-2 routing mechanism, and can track the locations of mobile stations based on Proxy Tables situated at Mesh Access Points. Although several location management or smooth handover techniques for WMNs have been proposed in the literature, none of them have tailored their proposal for 802.11s WMNs. They either adopt layer-3 routing or layer-2 rou
