Abstract:
Wireless networks have become popular in the last two decades and their use is since growing significantly. There is a concern that the existing resource of centralized networks may not sufficiently serve the enormous demand of customers. This thesis proposes one solution that has a potential to improve the network. We introduce decentralized networks particularly wireless ad-hoc networks, where users communicate and exchange information only with their neighbors. Thus, our main focus is to enhance the performance of data dissemination in wireless ad-hoc networks. In this thesis, we first exam

Abstract:
Recent widespread use of computer and wireless communication technologies has increased the demand of data services via wireless channels. However, providing high data rate in wireless system is expensive due to many technical and physical limitations. Unlike voice service, data service can tolerate delays and allow burst transfer of information, thus, an alternative approach had to be formulated. This approach is known as ???Infostation.??? Infostation is an inexpensive, high speed wireless disseminator that features discontinuous coverage and high radio transmission rate by using many short-

Abstract:
Caching at the network edge has emerged as a viable solution for alleviating the severe capacity crunch in content-centric next generation 5G wireless networks by leveraging localized content storage and delivery. Caching generally works in two phases namely (i) storage phase where parts of popular content is pre-fetched and stored in caches at the network edge during time of low network load and (ii) delivery phase where content is distributed to users at times of high network load by leveraging the locally stored content. Cache-aided networks therefore have the potential to leverage storage

Le stockage de contenu populaire dans des caches disponibles aux utilisateurs, est une technique émergente qui permet de réduire le trafic dans les réseaux sans fil. En particulier, le coded caching proposée par Maddah-Ali et Niesen a été considéré comme une approche prometteuse pour atteindre un temps de livraison constant au fur et à mesure que la dimension augmente. Toutefois, plusieurs limitations empêchent ses applications.

碩士<br>國立交通大學<br>電子研究所<br>106<br>In this thesis, we study a delay-aware cooperative online content caching mechanism in wireless networks with limited caching space in each base station (BS) and unknown popularity of the contents. An online algorithm is proposed for cooperative caching in multi-BS coordinated systems that does not require any knowledge of the contents popularities. When a new request from a user arrives at a BS, the BS responds the request by direct delivery if the requested content is currently cached in its storage space; otherwise, the BS sends a message to the Mobility Mana

The emerging peer-to-peer (P2P) overlay networks provide a promising scalable solution to the video streaming in the wired Internet. However, in wireless network environments, implementation of P2P is still challenged by the limited and asymmetric network bandwidth, high packet loss rate and mobile device’s resources.

Abstract:
For many data access applications, the availability of the most updated information is a fundamental and rigid requirement. In spite of many technological improvements, in wireless networks, wireless channels (or bandwidth) are the most scarce resources and hence are expensive. Data access from remote sites heavily depends on these expensive resources. Due to affordable smart mobile devices and tremendous popularity of various Internet-based services, demand for data from these mobile devices are growing very fast. In many cases, it is becoming impossible for the wireless data service provider

Abstract:
Mobile edge computing (MEC) can dramatically promote the compu- tation capability and prolong the lifetime of mobile users by offloading computation- intensive tasks to edge cloud. In this thesis, a spatial-random two-tier heterogeneous network (HetNet) is modelled to feature random node distribution, where the small- cell base stations (SBSs) and the macro base stations (MBSs) are cascaded with resource-limited servers and resource-unlimited servers, respectively. Only a certain type of application services and finite number of offloaded tasks can be cached and processed in the resource-limit

One of the goals of an operator is to improve the Quality of Experience (QoE) of a client in networks where Over-the-top (OTT) content is being delivered. The appearance of services like YouTube, Netflix or Twitch, where in the first case it contains more than 300 hours of video per minute in the platform, brings issues to the managed data networks that already exist, as well as challenges to fix them. Video traffic corresponds to 75% of the whole transmitted data on the Internet. This way, not only the Internet did become the ’de facto’ video transmission path, but also the general data traff

Abstract:
Network Coding is a critical technique when designing next-generation network systems, since the use of network coding can significantly improve the throughput and performance (delay/reliability) of the system. In the traditional design paradigm without network coding, different information flows are transported in a similar way like commodity flows such that the flows are kept separated while being forwarded in the network. However, network coding allows nodes in the network to not only forward the packet but also process the incoming information messages with the goal of either improving the
