TL;DR: This paper analyzes the handoff performance of SIP in a IP-based 4G network with Universal Mobile Telecommunication System (UMTS) and Wireless LAN (WLAN) access networks and shows that the minimum delay is unacceptable for streaming multimedia traffic and requires the deployment of soft-handoff techniques.

TL;DR: It is shown that the most significant difference of computing BDP and BDP-UB in MANET is the coupling of bandwidth and delay over a wireless link, where only one packet is allowed to be transmitted over the channel at a time.

TL;DR: An overview of extensible Retrieval, Annotation and Caching Engine (eRACE), a modular and distributed intermediary infrastructure that collects information from heterogeneous Internet sources according to registered profiles or end-user requests, is presented.

TL;DR: This work evaluates Web service performance of handheld resource-constrained clients using different wireless technologies and presents measurement results of a simple dynamic scheme that provides benefits by compressing responses only when the required server resources are available.

TL;DR: A new metric for quality assessment of long video transmissions (considerably longer than 10 s) is presented and applied to the simulation results and it is found that the combined system approach increases the number of supportable terminals per cell by up to 300%.

TL;DR: The proposed scheme offers a bandwidth routing protocol for QoS support in a multihop mobile network, namely link-state multi-path QoS routing, protocol in a wireless mobile ad-hoc network (MANET).

TL;DR: A new protocol called Load Aware Routing in Ad hoc (LARA) networks protocol for efficient data transmission in mobile ad hoc networks and defines a new metric for routing called traffic density to represent the degree of contention at the medium access control layer.

TL;DR: This paper analyzes simple slow CW decrease functions and uses simulations and mathematical modeling to show their considerable improvements at all contention levels and transient phases, especially in high congested environments.

TL;DR: An extension of Transmission Control Protocol (TCP) Westwood allowing the management of the Efficiency/Friendliness-to-NewReno tradeoffs is shown to be able to achieve higher total link utilization, yet at the same time maintain friendliness.

TL;DR: This paper proposes several novel solutions to the bandwidth-delay-constrained least-cost multicast routing problem based on genetic algorithms (GA), consisting of six different schemes for genotype representation, and also several new heuristic algorithms for mutation, crossover, and creation of random individuals.

TL;DR: Proposals for the enhancement of the 3G-security architecture, and the provision of advanced security services to end-user data traffic within and outside the UMTS core network are discussed.

TL;DR: The security threats and propose security services to counteract these threats in cluster-based NTDR ad hoc networks are described and secure schemes for a mobile node to initiate, join and leave a cluster are described.

TL;DR: It is argued that an energy map can be the basis for the entire design trajectory including all functionalities to be included in a wireless sensor network, and both probabilistic and statistical prediction-based approaches are proposed.

TL;DR: The state-of-the-art in router-based mechanisms to address the TCP-friendliness problem is surveyed and a description of the most important algorithms, design issues, advantages and disadvantages are presented, and a performance evaluation is presented.

TL;DR: A model of users' satisfaction is presented, which considers the effects of both users' request and price paid, and it is possible to investigate the relationship between the radio resource allocation and the provider revenue.

TL;DR: It is demonstrated that the distribution of packet arrival and the distributionof byte arrival in Ethernet network traffic are the alpha-stable distributions.

TL;DR: This paper applies energy saving mechanisms for security protocols in wireless networks to existing security protocols and demonstrates the reduction in energy consumption that is possible with the suggested approaches.

TL;DR: A new methodology for evaluating fault recovery performance of some existing mechanisms, which considers the establishment of quality of service network paths with protection and an analysis of the relationship between these protection components and different traffic classes is introduced.

TL;DR: It is found that higher mobility speed results in better connectivity, and irrespective of the speed, when multiple connected components are present, they typically consist of a very large component and (potentially several) extremely small ones, alluding to similarities to the 'giant component' in random graphs.
