It divides Low Earth Orbit (LEO) satellites into groups according to the the footprint area of the Medium Earth Orbit (MEO) satellites in each snapshot period. Based on the delay reports sent by LEO satellites, MEO satellite managers compute the minimum-delay paths for their LEO members. The snapshot and group decision method is detailed, the performance of SGRP is evaluated through simulations and analysis.","PeriodicalId":91426,"journal":{"name":"World of wireless mobile and multimedia networks.

The improvements due to our scheme are motivated by the observation that different applications typically have different preferences for latency and recency of data, which are not considered by traditional caching techniques. In our scheme, clients express their preferences using voluntary profiles: application-specific targets for latency and recency of data. We describe a complete framework for incorporating profile-based decision making into the cache utilization, downloading, and scheduling decisions at a mobile base station. We analyze the performance of profiles using simulations. Our results show that even simple profiles are useful in discriminating the service received by different applications, and using profiles in both caching and scheduling decisions improves performance. Further, clients who give uncooperative profiles increase the latencies of their own applications, thus providing all clients an incentive to provide fair and accurate profiles.","PeriodicalId":91426,"journal":{"name":"World of wireless mobile and multimedia networks.

Only uncompressed voice connections with Pulse Code Modulation (PCM) are supported, and 64Kbps bandwidth is assigned to each voice connection. However, with the use of speech coding techniques that produce compressed voice and/or detect silent periods, it is expected that high quality voice data can be transmitted at or below 4Kbps, and that the Bluetooth specification will support voice transmission at two or more distinct rates. A key issue that should be resolved in order to support variable rate coded voice transmission in Bluetooth is how to meet the temporal service requirements of various variable rate coded voices.In this paper, we propose, in compliance with the Bluetooth specification, a distance constrained scheduling (DCS)-based, intra-piconet scheduling algorithm to support admission control and scheduling of variable rate coded voice traffic, with the objective of providing the temporal quality of service requirement of each master-slave pair. Further, in the case that requests to establish voice connections exceed the system capacity, we present two admission control algorithms that select, based on utility functions defined, optimal subsets from an otherwise unschedulable request set. We also conduct simulations to evaluate the performance of the proposed algorithms in terms of schedulability, capability of delay jitter control, and effectiveness of admission control.","PeriodicalId":91426,"journal":{"name":"World of wireless mobile and multimedia networks.

Due to the highly varying characteristics of mobile wireless networks, one cannot merely rely on either network simulation or a testbed. Network emulation provides a controllable and reproducible environment, yet it generally lacks the support for the emulation of network topology and mobility, which are extremely critical in mobile wireless network research. We introduce EMWIN, a new IP-based mobile wireless emulation system that can overcome those drawbacks. In EMWIN, a target mobile wireless network is precisely mapped to an emulation configuration in a laboratory private network consisting of several emulator nodes, each of which is able to emulate multiple mobile hosts. Moreover, the emulator node can be flexibly configured such that predefined network conditions and traffic dynamics can be generated in an automatic manner. With EMWIN, the mobility of the target mobile wireless network with a number of mobile nodes can be faithfully emulated in a wired network environment.","PeriodicalId":91426,"journal":{"name":"World of wireless mobile and multimedia networks.

On the other hand, in mobile environments, the devices on which these applications must run have to minimize power consumption to prolong battery life. Our work focuses on the QoS issues in the event-driven distribution of multimedia streams between mobile users, where a source provides interactive video in the form of streams of data events to multiple remote sinks. This paper addresses the power-aware execution of event handlers at such event sinks. In particular, an adaptive approach to the dynamic selection of a suitable CPU clock frequency of a mobile device is shown superior to non-adaptive power management. This approach (a) minimizes power consumption while also (b) guaranteeing that a given event handler finishes its execution within application-specific timing constraints. This is realized by dynamically measuring the progress of event handler functions and then using this information to re-adjust the clock frequency for the current event and to select appropriate clock frequencies for future events.","PeriodicalId":91426,"journal":{"name":"World of wireless mobile and multimedia networks.

Yet, when the wired infrastructure (say, the Internet) is within reach, opportunistic connections to Internet sites may be established across the multihop network to transfer files and update databases. These file transfers use TCP for reliability and congestion control. However, recent experiments with ad hoc, multihop 802.11 networks have exposed serious instabilities when TCP connections span both wired and wireless domains. In particular, some TCP connections capture the wireless channel and drive the throughput on other connections virtually to zero. This is most surprising in view of the fact that connections between 802.11 (single hop) wireless LAN stations and the Internet are well behaved. In fact they are routinely used in most Campuses, Businesses and Research Labs. This paper is an experimental study of the unstable behavior of TCP across 802.11 ad hoc networks and the wired Internet. We investigate the fairness issues of multiple TCP flows as well as the coexistence of TCP flows and video streams in the wired/wireless scenario. Detailed analysis of the measurement results is also presented. The paper will prove very valuable to future commercial and military ad hoc networks.","PeriodicalId":91426,"journal":{"name":"World of wireless mobile and multimedia networks.
