Abstract We consider the problem of relay-assisted transmission for cellular networks. In the considered system, a source node together with relay nodes are selected in a proportionally fair (PF) manner to transmit to the base station (BS), which uses the maximal ratio combining (MRC) to combine the signals received from the source node in the first half slot and the relay nodes in the second half slot for successful reception. The proposed algorithm incorporates the PF criterion and cooperative diversity, and is called proportionally fair c ....etc

ABSTRACT
In cellular networks, QoS degradation or forced termination may occur when there are insufficient resources to accommodate handoff requests. One solution is to predict the trajectory of mobile terminals so as to perform resource reservations in advance. With the vision that future mobile devices are likely to be equipped with reasonably accurate positioning capability, we investigate how this new feature may be used for mobility predictions. We propose a mobility prediction technique that incorporat ....etc

Topic: fuzzy based call admission control in wideband cdma cellular networks

ABSTRACT
In this paper, a novel call admission control (CAC) scheme using fuzzy logic is proposed for the reverse page link transmission in wideband code division multiple access (CDMA) cellular communications. The fuzzy CAC scheme first estimates the effective bandwidths of the call request from a mobile station (MS) and its mobility information, and then makes a decision to accept or reject the connection request based on ....etc

A PROPOSED DISTRIBUTED CALL ADMISSION CONTROL SCHEME FOR MOBILE MICRO-CELLULAR NETWORKS
ABSTRACT
CAC scheme is a critical component to be considered for satisfying diverse Quality of service (QoS) requirements needed for future mobile networks. An attempt is made to suggest a new call admission control scheme in a distributed manner, considering the load conditions in all neighboring cells. The proposed admission policy is simple enough that the decision can be made in real time and hence suitable for micro-cellular netw ....etc

Cellular Neural Network is a revolutionary concept and an experimentally proven new computing paradigm for analog computers. Looking at the technological advancement in the last 50 years ; we see the first revolution which led to pc industry in 1980 s, second revolution led to internet industry in 1990 s cheap sensors & mems arrays in desired forms of artificial eyes, nose, ears etc. this third revolution owes due to C.N.N.This technology is implemented using CNN-UM and is also used in imageprocessing.It can also implement any Boolean functio ....etc

1. INTRODUCTION

In recent years, there has been a rapid increase in wireless network deployment and mobile device market penetration. With vigorous research that promises higher data rates, future wireless networks will likely become an integral part of the global communication infrastructure. Ultimately, wireless users will demand the same reliable service as today's wire-line telecommuni cations and data networks. However, there are some unique problems in cellular networks that challenge their service reliability. In addition to problems ....etc

Abstract
Virtual Cellular Networks (VCN) are an attractive type of adaptive
wireless communication architecture for propagation- and
coverage-limited environments. In this paper, we investigate the
advantages of combining a VCN and multiple receiving antennas
for the downlink resulting in a MIMO system. Several ways
to combine the signals with different levels of complexity are
presented. In the most complex case, we show that it is possible
to add coherently the contribution of each antenna in a virtual
cell ....etc

The design, construction and maintenance of buildings has a tremendous impact on our environment and our natural resources. The buildings all together use the one-third of all the energy consumed in the country and two-thirds of all electricity. So the challenges is to build them smart, so that they use a minimum of nonrenewable energy, produce a minimum of pollution and costs a minimum of energy, while increasing the comfort, health and safety of the people who live and work in them. Here comes green buildings which alienates the isolation of ....etc
