Mobile Handover

WiMAX dengan standar IEEE 802.16e merupakan suatu standar untuk sistem mobile WiMAX. Dalam sistem mobile ini mengenal adanya sistem handover. Simulasi pada penelitian ini terdapat 2 skenario, yang sama-sama menggunakan ASN-GW. Simulasi terdiri dari intra ASN-GW dan inter ASN-GW. Hasil dari simulasi yang telah dilakukan pada intra ASN-GW menunjukkan grafik throughput yang memperlihatkan terjadinya handover dari masing-masing nodal yang terlibat.Kata kunci: mobile, handover, VoIP, intra ASN-GW, inter ASN-GW, throughput.

The Impact

This chapter addresses the wireless communication aspect of traffic control in an urban vehicular environment. The IEEE 802.16e-2005 standard is used for Infrastructure to Vehicle communication. An architecture is developed with the target of minimizing overall data loss. Access Service Network Gateway (ASN-GW) is used to manage vehicle communication while roaming. OPNET simulations show that using ASN-GW gives good performance in mobility management. Simulations also show that introducing an interference source drastically degrades system performance. Using Dual Trigger HO (DTH) in a congested scenario improves system performance and reduces the impact of interference on the system.

Mobility Management Protocol

Selection of a MIMO (Multiple Input Multiple Output) antenna to achieve high throughput, minimize errors, and optimize data speed is an important design issue. Radio resource management to provide Quality of Service (QoS) in WiMAX involves dynamic scheduling of resources according to the user’s priority, based classes Platinum, Gold, Silver, and Bronze. Mobility and handoff management in WiMAX is another important issue involving location update, signaling traffic and service delay, and call blocking and dropping. This chapter focuses on some issues concerning MIMO configuration to improve transmit diversity, developing an appropriate scheduling algorithm to improve QoS, and presenting a novel mobility management protocol THMIP (Three Level Hierarchical Mobile IP) in IEEE 802.16e environment to reduce signaling cost with respect to QoS parameters like throughput, end-to-end delay, interference, path loss, bit error rate, and Signal-to-Noise Ratio (SNR). For the simulation, the authors use OPNET Modeler and MATLAB.

Abstract Design of single-feed circularly polarized (CP) microstrip antenna is proposed in this article. The design employs the concept of E-shape patch with inclined fractal defected ground structure (IFDGS), which can improve the impedance bandwidth, gain, and axial ratio (AR) bandwidth. The excellent enhanced impedance bandwidth, axial ratio bandwidth, and gain are achieved by an inclined E-shaped fractal etched on the ground plane. The parameter studies of the E-shaped IFDGS are given to illustrate the way to obtain CP radiation. The third iterative IFDGS is fabricated on easily available FR4 substrate with a size of 0.494 λ0 × 0.494 λ0 × 0.019 λ0 (λ0 is the wavelength in free space at 3.624 GHz). The measured results verify the simulated results and show good agreement. The proposed antenna shows an impedance bandwidth of 12.7% at a centre frequency of 3.47 GHz and 3-dB AR bandwidth for this band is 2.39% at a centre frequency of 3.626 GHz. The measured peak gain for the proposed antenna is found as 8.1 dBi. The proposed antenna can be suitable for mobile WIMAX operation (IEEE 802.16e-2005 standard), wireless communication in CA-band and FCC.

Bandwidth Partitioning

This paper addresses the issue of wireless bandwidth partitioning of a Mobile WiMAX cell. The authors consider a Complete Partitioning strategy, where the wireless bandwidth capacity of a cell is divided into trunks. Each partition is strictly reserved to a particular type of connection. Four IEEE 802.16e 2005 service classes are distinguished: UGS, rtPS, nrtPS, and ErtPS. The authors consider mobility and differentiate new call request from handoffs. In addition, the authors take into consideration the Adaptive Modulation and Coding (AMC) scheme, through the partition of the cell into different areas associated to a particular modulation and coding scheme. The purpose of the paper is to determine, using an analytical model and a heuristic approach, the nearly optimal sizes of the partition sizes dedicated to each type of connection, which is characterized by its service class, type of request and modulation, and coding scheme.
