....networks. Generally, each traffic of these media has a different stochastic property and an inherent requirement for quality of service. In order to adopt such a property and satisfy such a requirement, it is important to design an effective access control protocol for multimedia traffic[1]. A code division multiple access (CDMA) has become more popular for wireless communication networks. Various access control protocols for CDMA packet communication systems have been proposed in the previous works [2] 6] In a CDMA packet communication, fluctuation of the interference among ....

....QoS must also be addressed at the data link layer. The IEEE 802.11 [7] in PCF (Point Coordination Function) mode, the HiperLAN [18] and Bluetooth [19] achieve bounded latency by having a central station poll the slave stations. Most academic research has focused on this centralized approach [9], 8] The centralized approach is suitable for networks where only the last hop is wireless. In the centralized approach, the network is managed centrally from a central station. The Wireless Token Ring Protocol (WTRP) discussed in this paper is a distributed medium access control protocol for ....

....in TDMA, or orthogonal codes or hopping patterns in case of spread spectrum. Hybrid TDMA CDMA schemes benefit from both the capacity of TDMA schemes to handle high bit rate packet switched services, and the flexibility of CDMA techniques that allow smooth coexistence of different types of traffic [5]. In this chapter we will deal with three main aspects involved with energy efficient wireless communication: Medium Access Control (MAC) design, error control, and network interface architecture. Section 5.2 first presents the basics of wireless data link layer design issues are discussed, i.e. ....

....while they reduce the average error rate, they cannot typically differentiate between traffic of different connections. A MAC and link layer approach that is able to apply error control on a per traffic basis is an attractive alternative. These protocols, such as IEEE 802.11 [41] MASCARA [5], and E MaC [33] are or can be made traffic aware (rather than protocol aware) by tailoring the level of error control to the nature of the traffic (e.g. bounding retransmission for packets with a limited lifetime) 5.5.4 Related work Error control is an area in which much research has ....

....clients with a large prefetched reserve to successfully decode packets under adverse channel conditions. VI. RELATED WORK There is a large body of literature on providing QoS in wireless environments. Much of the work in this area has focused on mechanisms for channel access; see Akyildiz et al. [37] for a survey. Choi and Shin [38] have recently proposed a comprehensive channel access and scheduling scheme for supporting real time traffic and non real time traffic on the uplinks and downlinks of a wireless LAN. Recently, packet fair scheduling algorithms that guarantee clients a fair portion ....

....[3] 10] While the CDMA technology is expected to dominate for the third generation (3G) wireless systems, it is not suitable for typical WLAN environments since the data rate of an individual user can hardly be commensurate with the system bandwidth due to the spreading factor. The authors of [4] provide a good survey of MAC protocols covering both TDMA and CDMA based schemes for wireless multimedia networks while a good survey of wideband local access schemes comparing both wireless LAN and wireless ATM technologies can be found in [24] Recently, there have been significant research ....

In subsection 3. 2 we saw a similar logical channel structure in various multiple access schemes (FDMA, TDMA, CDMA, TDMA CDMA, A multiple access scheme of a MAC protocol establishes a method of dividing the transmission resources into accessible sections [8]. Transmission channels, defined in our logical structure of the PLC systems (section 3) represent the sections which are accessible for the MAC protocol. In the OFDM system presented in subsection 2.3 the transmission channels are distributed in a frequency spectrum, which concerns a kind of ....

Each of the multiple access methods can be combined with a duplex scheme. In telecommunication system there are two duplex schemes (e.g. 6] and [8]) FDD Frequency Division Duplex . TDD Time Division Duplex A TDMA FDD solution is applied in GSM mobile networks and TDMA TDD is used in DECT wireless systems. Any of the duplex solution can be also applied to the PLC systems according to used multiple access scheme and features of the ....

....range, and transmitter power for wireless links. The latter point of view, however, was inspired by the high error rate on wireless links, where a high error rate on a large frame might not be efficient. There are many ways in which these principles can be implemented. Several researchers (e.g. [4][9] 57] have compared various mechanisms. 23 6 Energy efficient error control Since high error rates are inevitable to the wireless environment, energy efficient error control is an important issue for mobile computing systems. This includes energy spent in the physical radio transmission ....

....the transmission capacity of the PLC systems seems to be limited. The restricted capacity of the PLC networks calls for an adequate MAC (Medium Access Control) protocol. A multiple access scheme of a MAC protocol establishes a method of dividing the transmission resources into accessible sections [5]. Multiple access scheme to be applied to the PLC systems depends on the used multiplex method. If we consider an OFDM based system, as described in previous subsection, with its ability to build up the transmission channels consisting of several subcarriers, a suitable multiple scheme is OFDMA ....
