QoS Support in TDMA-Based Mobile Ad Hoc Networks

Abstract

Mobile ad hoc networks (MANETs) are gaining a lot of attention in research lately due to their importance in enabling mobile wireless nodes to communicate without any existing wired or predetermined infrastructures. Furthermore, in order to support the growing need for multimedia and realtime applications, quality of service (QoS) support by the networking protocol is required. Several important QoS parameters that are needed by such applications can be identified. They include bandwidth, end-to-end delay, delay jitter, and bit error rate. A good amount of research has been developed in this area covering different issues and challenges such as developing routing protocols that support bandwidth reservation and delay management. In this paper, the current state of research for QoS support in TDMA-based MANETs at the different layers of the networking model is presented and categorized. In addition, the current issues and future challenges that are involved in this exciting area of research are also included.

Quality Measurements on the Radio Interface of the Mobile Communication in the Proximity of the Power System

“…The influence of these propagation environments to the GSM cellular mobile network are widely used by many authors in the real-time requirements of mobile telecommunication systems (Hata, 1980;Capsoni et al, 2009;Athanasiadou et al, 2000;Anderson, 2003;Abhayawardhana et al, 2005;Tan et al, 2003;Low, 1992;Jawhar and Wu, 2005;Chen et al, 2005;Srivastava and Mishra, 1997;Ronchini and Gaiani, 1998;Tunnicliffe et al, 1997;Sathyendranl and Smith, 1998;Silventoinen et al, 1997;Islam et al, 2006;Ismail et al, 2010;www.anite.com/nemo). Different propagation models are used extensively in GSM network planning and can be broadly categorised into three types models respectively, empirical, deterministic and stochastic (Hata, 1980;Capsoni et al, 2009;Athanasiadou et al, 2000;Anderson, 2003).…”

“…The research for QoS support in TDMA-based mobile networks at the different layers of the networking model is presented and analysed (Jawhar and Wu, 2005). Chen et al (2005), proposed a scalable framework Q-GSM for service management in grid environments, to meet the requirements of both grid users and service providers.…”

Inter-vehicular Communication Systems, Protocols and Middleware

“…The survey briefly discusses the different routing mobile ad hoc network (MANET) protocols [4][5] including flat, hierarchical, location-based, geographical, and geographical multicast routing. In addition, an overview of the mobility management aspects of IVC systems is presented including location management, and handover mechanisms using mobile IP, cellular, and vehicular strategies.…”

Monitoring Linear Infrastructures Using Wireless Sensor Networks *

“…These issues are efficient routing protocols for ad hoc and wireless sensor networks [8], QoS support [7][9], security [2], and middleware [4]. Most of these issues are investigated under the assumption that the network used for sensors does not have a predetermined infrastructure [3] [5][10] [11].…”
