The Next generation mobile communication system called as 4G is expected to include heterogeneous wireless networks that will offer high data rate multimedia services to end users. In present wireless systems the capability of broader coverage is available but has the limitation of bandwidth and network cost. The proposed Seamless Media Independent(More)
A Vehicular Ad-Hoc Network or VANET is a technology for implementing Vehicle-to-Vehicle (V2V) and Vehicle-to-Infrastructure (V2I) communications. The present Vehicular mobility framework is not considering realtime constraints such as vehicle’ priority, lane-changes, speed-limit etc. The proposed Multi-Constraint Realtime Vehicular (MCRV) mobility framework(More)
Ontology‟s have recently received popularity in the area of knowledge management and knowledge sharing, especially after the evolution of the Semantic Web and its supporting technologies. Ontology defines the terms and concepts (meaning) used to describe and represent an area of knowledge. The aim of this paper is to identify all possible existing(More)
In Wireless era, Cross-layer designing of transmission power assignment and power control is the critical issues in emerging wireless technology. Intelligent transmission power selection algorithm depends on the notion of Transmission Power (TXPOWER), energy, Received Signal Strength Indication (RSSI) and the distance. The decentralized network without load(More)
In the literature, the Error Correcting Codes [ECC] are utilized in modern Communication system to make high speed data transfer over the channel and transferred data reappear reliably at the receiver end. Viterbi decoder is the best solution in maximum likelihood sense to decode for forward error correction of convolutionally encoded messages. In this(More)
Core based design has become the de-facto design style for many VLSI design houses, as it facilitates design reuse, import of specialized expertise from external vendors and leads to a more streamlined design flow. Pre-designed cores and reusable modules are popularly used in the design of large and complex Systems-on-aChip (SOC). Embedded cores such as(More)
Test Methodologies for Globally Asynchronous Locally Synchronous (GALS) System On a Chip (SOC) are a subject of growing research interest since they appear to offer benefits in low power applications and promise greater design modularity. Pre-designed cores and reusable modules are popularly used in the design of large and complex Systems. As the size and(More)
