FDA: A Novel Base Station Flow Control Scheme for TCP over Heterogeneous Networks
White Paper FDA is implemented at the base station (BS) of a wireless network. In this paper, a novel proactive base station flow control algorithm, called Forced Duplicate Acknowledgement (FDA), is proposed for extending TCP over wireless networks. [03 Jul 2008]
Channel Pre- and Post-Equalization in Uplink OFCDM Systems With Mobility
White Paper This paper proposes an up-link Orthogonal Frequency and Code Division Multiplexing (OFCDM) mobile cellular system that uses channel pre-equalization at the Mobile Terminal (MT) and adaptive detection at the Base Station (BS). [03 Jul 2008]
The Simple Information Security Audit Process: SISAP
White Paper The SISAP employs a simulation-based rule base generator that balances risks and business value generation capabilities using the Plan-Do-Check-Act cycle imposed in BS 7799.2. The SISAP (Simple Information Security Audit Process) is a dynamic... [13 May 2008]
Effective Throughput: A Unified Benchmark for Pilot-Aided OFDM/SDMA Wireless Communication Systems
White Paper This paper studies the uplink performance of an orthogonal frequency division multiplexing (OFDM) wireless system where multiple antennas are utilized at the base station (BS). Further, capacity can be greatly enhanced through spatial division... [10 Apr 2008]
TCP Performance Enhancement by Implicit Priority Forwarding (IPF) Packet Buffering Scheme for Mobile IP Based Networks
White Paper Smooth handoff by the route optimization extension of Mobile IP standard should support packet buffering mechanism at a Base Station (BS) in order to prevent TCP performance degradation due to packet losses in mobile networks environment. [14 Jan 2008]
A Flow Control Scheme for Improving TCP Throughput and Fairness for Wireless Networks
White Paper When multiple TCP connections are concentrated on a Base Station (BS), it is liable to be a bottleneck and the difference of network bandwidth between wired and wireless links aggravates the situation. [14 Jan 2008]
The Time Division Duplex: Mode in the UMTS
White Paper An RNS is further divided into the Radio Network Controller (RNC) and multiple Node Bs, also known as Base Stations (BSs). The Node Bs/BSs are connected to the RNC by the Iub interface. The 3rd Generation Partnership Project (3GPP) is a... [07 Jan 2008]
A Medium Access Control Protocol for Radio Over Fiber Wireless LAN Operating in the 60-GHz Band
White Paper A system based on this technology has properties quite different from those of conventional WLAN systems in that every room in a building hosts at least one picocell having its own Base Station (BS). Radio over Fiber (RoF) technology has been... [05 Dec 2007]
Performance Evaluation of a MAC Protocol for Radio Over Fiber Wireless LAN Operating in the 60-GHz Band
White Paper That is, every room in a building should have at least one Base Station (BS). Wireless networks using Radio over Fiber (RoF) technology operating in millimeter-wave (mm-wave) bands have been suggested as promising solutions to meet increasing user... [05 Dec 2007]
Jamming Resistant Architecture for WiMAX Mesh Network
White Paper The main idea is to use multiple Base Stations (BS), access points to the fixed core network. When the nodes are affected by jamming they can reroute to another base station if possible. This will facilitate network survivability both in case of BS... [23 Aug 2007]
Optimization of a Wireless Access Network
White Paper N Base Stations (BSs) at fixed locations are to be connected to a subset of M possible sites for Mobile Switching Centers (MSCs) in a cellular access network. Given the BS-MSC connection cost matrix, the MSC-LE connection vector, the MSC equipment... [23 Aug 2007]
A Topology-Aware Routing Protocol for the MANET With Multiple Sinks
White Paper In this paper, a topology-aware routing protocol is developed for the Mobile Ad-hoc NETworks (MANET) with multiple fixed Base Stations (BSes). The protocol aims at delivering packets reliably from the source node to its nearest BS. [01 Aug 2007]
Design and Analysis of Low-Power Access Protocols for Wireless and Mobile ATM Networks
White Paper The network is based on the infrastructure model where a Base Station (BS) serves all the mobiles currently in its cell. This paper describes the design and analysis of a low-power Medium Access Control (MAC) protocol for wireless/mobile ATM networks. [20 Jul 2007]
Opportunistic Feedback in Clustered OFDM Systems
White Paper This paper proposes a random access based feedback protocol for the clustered Orthogonal Frequency Division Multiplexing (OFDM) downlink, which allows users to feed back their channel information to the Base Station (BS) in a distributed fashion. [11 Apr 2007]
On Pilot-Symbol Aided Channel Estimation for MC-CDMA in the Presence of Cellular Interference
White Paper The system performance in presence of a synchronization mismatch between two interfering Base Stations (BS) is analysed in the way that a mobile terminal receives the perfectly synchronized signal from the desired BS as well as the signal from one... [16 Feb 2006]
