A survey, classification and comparative analysis of medium access control protocols for ad hoc networksPage(s): 2 - 16
Recent technological advances in wireless communications offer new opportunities and challenges for wireless ad hoc networking. In the absence of the fixed infrastructure that characterizes traditional wireless networks, control and management of wireless ad hoc networks must be distributed across the nodes, thus requiring carefully designed medium access control (MAC) layer protocols. In this article we survey, classify, and analyze 34 MAC layer protocols for wireless ad hoc networks, ranging from industry standards to research proposals. Through this analysis, six key features emerge: (1) channel separation and access; (2) topology; (3) power; (4) transmission initiation; (5) traffic load and scalability; and (6) range. These features allow us to characterize and classify the protocols, to analyze the tradeoffs produced by different design decisions, and to assess the suitability of various design combinations for ad hoc network applications. The classification and the tradeoff analysis yield design guidelines for future wireless ad hoc network MAC layer protocols. View full abstract»
This article outlines the challenges of IP multicast over Mobile IP. Then it provides a comprehensive overview of existing multicast solutions to handle mobile sources and receivers in both the Mobile IPv4 and the Mobile IPv6 environments. The solutions are classified into different classes in light of how the network infrastructure is used and the nature of the multicast members (receivers or sources). For each solution, we present a brief overview; we describe the architecture and the proposed protocol; we discuss the advantages and the limitations; and we compare qualitatively all the solutions of each class based on common criteria such as optimal routing, join latency, handover transparency, etc. View full abstract»
QoS control for video and audio communication in conventional and active networks: Approaches and comparisonPage(s): 42 - 49
Various levels of Quality of Service (QoS) can be provided within a network by using integrated services, differentiated services, and active networking approaches. While these three approaches have been presented in several articles, comparison among them is lacking. Therefore, this article examines these three approaches for both their key functionality and their relative strengths and weaknesses of QoS control techniques for video and audio. Future research directions of each approach for supporting QoS for video and audio traffic are also discussed. View full abstract»
Charging, accounting and billing management schemes in mobile telecommunication networks and the internetPage(s): 50 - 58
The current technological advances in mobile telecommunication networks and the Internet are about to alter existing business models. These different worlds converge and create an open market, where a large number of independent application/service providers will offer their services to users through a limited number of network providers. At the same time, the evolution of existing network technologies and the specification of new concepts requires new advanced and holistic solutions in several technical areas. One such area is related to the design and management of new sophisticated functions and protocols to support innovative, flexible, and efficient charging, accounting, and billing mechanisms. This survey article considers the key concepts of such mechanisms, and the requirements they impose upon the network infrastructure. The article presents the latest efforts undertaken by standardization bodies in the mobile telecommunication industry as well as by Internet Working Groups to meet these requirements.
