A Dynamic Load Balancing in Wireless CDMA Cellular Networks
White Paper The load balancing problem is formulated as an integer linear program which minimizes the unserved traffics and handoff calls in the network. With the increase of cellular users the traffic hot spots and unbalanced call distributions are common in... [10 Jul 2008]
Integration of MobileIP/CellularIP
White Paper The same scheme applies when a roaming mobile host enter another cellular ip network from current network, i.e.a Macro-Handoff. To investigate the "Macro-handoff" between two CellularIP networks, we integrated into Gateway the periodical task... [03 Jul 2008]
Seamless Handoff in Community Based and Location Aware Heterogeneous Wireless Networks
White Paper The fast growing number of WLAN hotspots (restricted or unrestricted access) especially in densely populated cities may be able to provide the bandwidth current cellular network technologies such as GPRS cannot, and UMTS in the near future will... [03 Jul 2008]
An Enhanced Handoff Mechanism for Cellular IP
White Paper This paper presents a lossless and duplication free handoff scheme called LPM (Last Packet Marking) for improving Cellular IP semisoft handoff. Handoff is one of the most important factors that may degrade the performance of TCP connections in... [14 Jan 2008]
Impact of Soft Handoff on TCP Throughput Over CDMA Wireless Cellular Networks
White Paper In CDMA cellular networks, the soft handoff technique allows a mobile host to communicate with multiple base stations simultaneously, improving the transmission quality of the wireless channel and avoiding disconnection upon to base station... [14 Jan 2008]
A Simulation Environment for Analysis of QoS and Signaling Load in Mobile Cellular Networks
White Paper CELSA1 (Cellular Signaling Analyzer) is used for study of signaling load in mobile cellular networks, through the cost analysis of implemented procedures like power up, power down, call origination, handoff and location updating. [23 Aug 2007]
Priority-Determined Multiclass Handoff Scheme With Guaranteed Mobile QoS in Wireless Multimedia Networks
White Paper In multimedia cellular networks, one should not only minimize the dropping rate of handoff calls, but also control the blocking rate of new calls at an acceptable level. This paper proposes a novel multiclass call-admission-control mechanism that... [01 Aug 2007]
Dynamic Step-Size Power Control in UMTS
White Paper Furthermore, dynamic inter-operation between the power control, admission control, and handoff control is evolved to improve the convergence of the proposed power control mechanism. This paper proposes a novel dynamic step-size power control method... [01 Mar 2007]
OmniCon: A Mobile IP-Based Vertical Handoff System for Wireless LAN and GPRS Links
White Paper Recognizing that 2.5G or 3G cellular networks can effectively complement wireless LANs, the authors set out to develop a vertical handoff system that allows mobile users to seamlessly fall back to such cellular networks as GPRS or 3G whenever... [30 Jun 2006]
Performance of Neural Network Handoff Algorithm Under Varying Mobile Velocities
White Paper This paper analyses the effects of training on the performance of neural network handoff algorithm in a micro-cellular environment. The paper first describes the neural network handoff decision algorithm as it is applied to the handoff scenario and... [24 May 2006]
BlueMobile - A Mobile IP Based Handoff System for Bluetooth, 802.11 and GPRS Links
White Paper Complementing Bluetooth with 802.11 and cellular network technology like GPRS would solve the shortcomings of these three technologies. Ad-Hoc networks using Bluetooth technology has gained immense popularity among the networking community. [19 May 2006]
Policy Based Mobile IP Handoff Decision (Polimand) Using Generic Link Layer Information
White Paper This paper describes a first implementation of a policy based Mobile IP handoff decision (POLIMAND) which uses link layer parameters for MIP handoff decisions. There is currently a large variety of heterogeneous wireless access networks and... [17 May 2006]
Using MPLS-Based Dynamic Tunnel for Location Control and QoS Management in Wireless Network
White Paper To use the media service, one needs stable bandwidth and bundle delay time because in 3G cellular network, the IP handoff problem may come from the faster speed than that in wireless network. Therefore, this paper proposes QoS architecture to... [12 May 2006]
An Adaptive QoS Management Scheme for Interworking Cellular and WLAN Networks
White Paper To provide end-to-end Quality of Service (QoS) support is one of the key issues towards such a goal, due to the various constraints, such as the unbalanced capacity of two systems, handoff from users' mobility and unreliable wireless media. [09 Feb 2006]
Optimal Joint Session Admission Control in Integrated WLAN and CDMA Cellular Networks With Vertical Handoff
White Paper The paper proposes a joint session admission control scheme for multimedia traffic that maximizes overall network revenue with Quality of Service (QoS) constraints over both the WLAN and the CDMA cellular network. [07 Feb 2006]
