Cooperative System for 4G Wireless Communication Networks

چکیده
Various services supports are the principal requirements of the Fourth Generation (4G) system; therefore, the need to improve integration of heterogeneous networks is significant. This paper amends EVOLUTE (a project of Information Society Technologies (IST)) to strengthen mobility management. This paper uses Multicast-based Mobility (M&M) to aid Cellular IP (CIP) in micro-mobility management. The aim of this paper is to produce complete integration of heterogeneous networks to support fine-fit mobility management for seamless handoff. The cooperative M&M/CIP is suitable for macro-mobility management, proposed by EVOLUTE, to support real-time and non-real-time data flow in micro-mobility management. Simulation results prove that the proposed system achieves good performance than other existed methods. Keywords—4G, integration of heterogeneous wireless networks, micro-mobility management, hierarchical mobility management

Performance Analysis of Wireless Cooperative Networks with Iterative Incremental Relay Selection
In this paper, an iterative incremental relay selection (IIRS) scheme is considered for wireless cooperative networks in order to increase the reliability of transmission. Different from the conventional incremental relay selection which incrementally selects a best relay for only one iteration; the IIRS scheme iteratively applies the incremental relaying and relay selection processes. To evalu...
متن کاملThe Role of Regulatory in Price Control and Spectrum Allocation to Competing Wireless Access Networks
With the rapid growth of wireless access networks, various providers offer their services using different technologies such as Wi-Fi, Wimax, 3G, 4G and so on. These networks compete for the scarce wireless spectrum. The spectrum is considered to be a scarce resource moderated by the spectrum allocation regulatory (“regulatory” for short) which is the governance body aiming to maximize the socia...
متن کاملSum-Rate Maximization Based on Power Constraints for Cooperative AF Relay Networks
In this paper, our objective is maximizing total sum-rate subject to power constraints on total relay transmit power or individual relay powers, for amplify-and-forward single-antenna relay-based wireless communication networks. We derive a closed-form solution for the total power constraint optimization problem and show that the individual relay power constraints optimization problem is a quad...
متن کاملCooperative Personal Ubiquitous Environments and Services – A Novel Dimension of Cooperation in 4 G –
Fourth Generation (4G) of wireless networks is no more a dream, already knocking at the doors of our information village. 4G promises to offer a vast range and diversity of converged devices, services and networks in order to revolutionize the way we communicate today. 4G would also influence today's networking architecture where the inter-user communication is realized with the help of third-p...
متن کاملCooperative Header Compression for 4G Wireless Networks
In this paper we introduce an cooperative header compression scheme for 4G wireless networks. The main focus is to achieve robustness and low complexity for the compression. Furthermore the header compression scheme should work without any feedback information.
