The wireless local area network (WLAN) is becoming popular due to its inherent strength. However, there are major challenges to be over come in WLAN. Some of them are quality of service (QoS), seamless mobility and security. Extensive research is being carried out to address QoS in WLAN. In this paper we propose a new medium access control (MAC) protocol for QoS (New-MACQoS) in WLAN. It has been observed that, the average delay performance by this New-MACQoS for different services (voice, video, best-effort data) is better than the extended distributed coordination function (LDCF) used in IEEE 802.11e and adaptive EDCF (AEDCF) in Qiang Ni, (2005) for QoS of WLAN

Wireless local area networks (WLANs) or the IEEE 802.11 networks are one of the most popular mediums for interconnecting portable devices. All the stations communicating over WLANs share a common wireless channel. In order to avoid potential collisions, an RTS-CTS handshake procedure is used to acquire the channel. However, most of the existing channel reservation protocols in WLANs view the wireless channel capacity as time invariant for each station which results in poor channel utilization. This paper introduces a handshake based channel aware MAC protocol that assigns the channel according to its fading status observed by each station while ensuring fairness in the access of the channel by all the stations. The uplink and downlink flows are also equalized. This protocol improves the channel utilization and also reduces the packet error rate

The energy driven cluster-head rotation (EDCR) algorithm proposed in S. Gamwarige and E. Kulasekere (2005) has been shown to out performed existing clustering algorithms such as LEACH (W.B. Heinzelman et al., 2002), HEED (O. Younis and S. Fahmy, 2004), ANTCLUST based (J. Kamimura et al., 2004) and SEP (G. Smaragdakis et al., 2004) in terms of END and PNA (95%) lifetime metrics in a distributed wireless sensor network (WSN). In this paper we present theoretical analysis of the performance parameters such as the optimum transmission range (Ropt) and the clustering trigger threshold value (lambdai) of EDCR in terms correctness and complexity of the algorithm. Further we explain how to find the optimal values for such parameters in order to maximize the network lifetime

Advances in high speed network communications have raised the bar of delivering demanding multimedia and data services through Ethernet passive optical networks (EPONs). At their relatively low cost, EPONs have become an attractive solution to providing essential services like voice, video, and data communications reliably, while at the same time providing expected guarantees of the delivery of those services in terms of defined quality of service measures. A continuous theme throughout EPON research has been the study of efficient dynamic bandwidth allocation (DBA) as a key factor in achieving fairness in distributing bandwidth amongst remote network units. In our research, we investigate another factor and its effect of network performance and service delivery: cycle demand proportionality (CDP). By observing the patterns of demand in the network on an individual network unit basis cycle after cycle, we can deduce load characteristics of some units over others. We can then make decisions about subsequent grant allocations based on this factor and aim to achieve better results in the process. We simulate EPONs under varying loads and incorporate the use of CDP in conjunction with currently used DBA schemes. In this paper we present results of achieving improvements in delay performance under light-load circumstances for the cyclic polling DBA scheme

Directional beams can increase the spatial reuse of ad hoc networks, also the limited beamwidth decreases the mutual interference among transmitting signals, so, the performance and the anti-jamming ability are improved greatly. This paper analyzed the existent interferences in ad hoc networks, indicated corresponding methods, and proposed a scheme of using directional antennas. Supported by group mobility scenarios, detailed simulations and evaluations have been done, and results demonstrate the availability of the scheme

The basic obligation of a wireless system is to provide scope for maximum mobility (terminal) while the system continues to provide the services at agreed levels of quality. The fundamental requirement for the system to support mobility is that it must be aware of the location where the mobile terminal (MT) resides at any point of time. The importance of mobility prediction techniques can be seen at both the network and service levels. This paper proposes a novel mobility prediction technique based on user activity pattern that could overcome some of the drawbacks associated with regular pattern based techniques available in the literature

Digital video broadcasting (DVB) technology can be used for providing Internet protocol (IP) based services along with audio and video broadcasting. A new protocol, called unidirectional lightweight protocol (ULE) has been defined by the IETF for the transport of IP datagrams over DVB. ULE provides several benefits over the existing mechanisms used in DVB for transporting IP data. This paper describes an extension to the ULE protocol to provide security for IP services over DVB. The different security requirements for IP over DVB services are discussed. The mechanisms and security extensions for ULE to satisfy these requirements are described. Simulation results are also presented to show the impact of these security mechanisms on the IP traffic

The characteristics of mobile adhoc network (MANET), has made the design of efficient routing protocols a critical research challenge. Use of location information in routing is often proposed as a means to achieve scalability. The major issue in location based routing is effective implementation of location management functions so as to reduce the costs associated with them. In this paper, we propose circular layer location management (CLLM) scheme which employs circular layer architecture and multigrained location information organization. Here we show that following our scheme, we can achieve a good asymptotic bound for both location updation and query costs

Implicit training (IT) based channel estimation exploits the first order statistics in the received data, induced by superimposing periodic training sequences with good correlation properties, along with information symbols. Hence the need for additional time slots for training the equalizer is avoided. In this paper we investigate on the applicability of this technique to orthogonal frequency division multiplexing (OFDM) systems over a frequency selective fading channel. Based on the estimate, a zero forcing solution is used to equalize the channel. The effect of the deterministic mean of the data on the channel estimate is considered. By exploiting the periodicity of the training sequences in the frequency domain, improved estimates of the channel coefficients are obtained. The performance of the estimator is presented in terms of the mean square estimation error (MSEE) and uncoded bit error rate (BER). All the improvements come at the cost of a loss in bandwidth which makes this scheme similar to the comb type pilot based channel estimation scheme for OFDM

Radiation scattered from a parabolic index planar waveguide with the insertion of metal strip at the centre is analyzed to design the photonic antenna, which transfers the energy from waveguide to free space, using beam propagation method (BPM). This technique allows the interpretation of the metal strip as scattering element of the underlying waveguide mode and radiating sources for the diffracted fields. The parabolic index planar waveguide with the insertion of metal strip with high refractive index value is evaluated and often explicit formulas for the radiating parameters of photonic antennas. The framework allows separation of the effects of the metal strip insertion with high refractive index value and the effects of the specific size of the metal strip element. A straightforward analogy between the effects of the metal strip element's refractive index value, shape and the behaviour of photonic antenna systems allow a clear and sensitive understanding of the effects of metal strip on the directionality of waveguide coupled radiation. The results covered only TE modes and it is possible to achieve high directional photonic antennas in the range of optical wireless frequencies. The results are obtained for various operating wavelengths of parabolic index waveguide structure with power distribution along z-direction and the efficient wavelength is proposed for photonic antenna
