Abstract

The integration of LTE –WiMax wireless mobility aids in seamless mobility and cost effective mobile data services with the use of IP core and OFDMA air interface technology. The onslaught of 3G/4G and Wifi/WiMax interworking capabilities introduces a multitude of possibilities like security and Quality of Service (QoS). Each network has several similarities and has its own technology for authentication and link layer security. The interworking is performed on a data link layer using EAP authentication protocol by integrating key authentication procedure. In this paper, security key management for various protocols and its numerical analysis are presented across interworking domain. Interworking security is isolated in view of the fact that the authentication protocol has its limitation. It is desirable to avoid several round trips, delays in handover, computational overhead, hence a fast re-authentication procedure has been proposed in LTE-WiMax network.

Abstract

Today’s process industries have increasingly come to rely on information gained from networks of sensors installed at key points through the factory or field site. Measurement of air pressure, electrical current, weight load, fuel levels, temperature, corrosion, pipe flow, seismic activity – such readings are critical to the effective and efficient safe operation of oil pipelines and refineries, pharmaceutical and chemical companies, food and beverage manufacturers, and power plants. The evolution of sensor technologies has enabled managers and administrators to gain more insight into complex processes. For example, the introduction of microprocessors and digital communications led to Distributed Control Systems (DCSs) and the migration of intelligence into field devices, allowing enterprises to improve operations significantly. The main idea of our work is to provide a low cost, reliable and secured wireless automation using sensor networks through an efficient routing protocol, which would be compatible for industrial and home applications and to offer significantly improved monitoring, reduced energy consumption and power dissipation.

Abstract

OFDM (Orthogonal Frequency Division Multiplexing) is one of the major multicarrier systems used in present day wireless communications. The capability to meet out the demand for very high data rate with in the restricted bandwidth makes it more popular. The evolving technology improves the OFDM by replacing the conventional FFT based system with DWT-OFDM. This emerging trend is currently in the laboratory level. This paper discusses about the selection of suitable modulation scheme for DWT OFDM, after simulating the different possible M-ary methods with various constellation levels. Rayleigh fading channel environment for simulation was created using MATLAB program and the results infer that the QAM is the most suited procedure for DWT based OFDM.

Abstract

Mobile Communication devices such as cellular phone, laptops, and PDAs are typically equipped with multiple radio access interfaces in the current trend. The opportunity to attach to more than one access network at a time makes users capable of roaming over access technologies and administrative domains seamlessly. Soft HO can easily be implemented and load balancing is possible to leverage when the amount of traffic exceeds the capacity of one single radio access interface. The aim of this Research work is to present the relative presentation of MIP and Seamless IP diversity based Generalised Mobility Architecture using the simulation setup using mSCTP for the video streaming. To set the research work in background, it explains the latest work which has been complete to advance the capability of MIP.

Abstract

MIMO (Multiple input –Multiple Output) technology is a promising and upcoming technology for the future wireless generation system, as it has got high throughput and diversity gain. MIMO makes antennas work smarter by enabling them to combine data streams arriving from different paths and at different times to effectively increase receiver signal-capturing power. MIMO is used in modern wireless standards, including in IEEE 802.11, 3GPP LTE, and mobile WiMAX systems.Sphere decoding algorithm is a lattice reduction algorithm introduced for low complexity MIMO detection SD is a powerful and attractive tool to achieve a high performance close to the Maximum Likelihood (ML),Zero Forcing (ZF) but with less complexity. This paper presents a simulation study on the sphere decoding method and compares the performance with other classical MIMO scheme such as VBLAST and Zero forcing receivers. The simulation tool used is MATLAB communication tool box version 7.1. The performance metric considered is Bit Error Rate (BER) and the channel is assumed to be Rayleigh fading. It is inferred that detection is possible with complexity and gives a better result in terms of Bit Error Rate when comparing general sphere decoding and MMSE.
