With the rapid development in mobile network we need effective network planning tool to satisfy the need of customers. However, deciding upon the optimum placement for the base stations (BS) to achieve best services while reducing the cost is a complex task requiring vast computational resource. This paper addresses antenna placement problem or the cell planning problem, involves locating and configuring infrastructure for mobile networks. The Cluster Partitioning Around Medoids (PAM) original algorithm has been modified and a new algorithm M-PAM (Modified-Partitioning Around Medoids) has been proposed by the authors in a recent work. In the present paper, the M-PAM algorithm is modified and a new algorithm CWN-PAM (Clustering with Weighted Node-Partitioning Around Medoids) has been proposed to satisfy the requirements and constraints. Implementation of this algorithm to a real case study is presented. Results demonstrate the effectiveness and flexibility of the modifying algorithm in tackling the important problem of mobile network planning.

A generalized blind lag-hopping adaptive channel shortening (GLHSAM) algorithm based upon squared auto-correlation minimization is proposed. This algorithm provides the ability to select a level of complexity at each iteration between the sum-squared auto-correlation minimization (SAM) algorithm due to Martin and Johnson and the single lag auto-correlation minimization (SLAM) algorithm proposed by Nawaz and Chambers whilst guaranteeing convergence to high signal to interference ratio (SIR). At each iteration a number of unique lags are chosen randomly from the available range so that on the average GLHSAM has the same cost as the SAM algorithm. The performance of the proposed GLHSAM algorithm is confirmed through simulation studies.

In wide area ubiquitous wireless networks, most wireless terminals (WTs) will transmit small amounts of data at comparatively long intervals. Therefore, each AP must be capable of accommodating a great many WTs. Moreover, this network is required to accommodate a variety of services; some services need to be prioritized. In this paper, we propose a novel prioritized control scheme that applies random access to wide area ubiquitous wireless networks. Two kinds of priority classes are considered; high priority (HP) class and low priority (LP) class. The transmission performance of HP class must be guaranteed regardless of LP class traffic situation. To meet this requirement, the proposed scheme isolates the random access (RA) periods of the two classes and controls the RA period for HP class according to the HP class traffic situation, which is predicted from the HP event notification history (event here means that a WT has HP traffic to send). This paper also clarifies the problems of the conventional scheme and reveals the transmission performance of the conventional and proposed scheme by computer simulation.

As we observe society in our days, we can see that people live longer; this means that we have an older population. As we know, elder are more likely to have health issues. The special needs presented by elder are gaining a major concern from all of us. Another tendency of our society is the lack of time that people demonstrate and, as a consequence, the lack of time reflects when families can't take care of their own elders. Many solutions are being presented in order to solve this problem. Some of them are taking advantage of the new technology developments in body sensor network area. In this paper we proposed an architecture of a system called elder care. The elder care solution has two primary goals: monitoring vital signs, sending alerts to family and specialized help and provide a social network in order to wrap all elder to avoid social isolation.

A new field of physics has appeared with the emergence of materials known as "Left handed materials" (LHM) or "metamaterials". These materials show very particular characteristics. Their index of refraction has a negative value, which results in the reversal of Snell's law. Whereas, in traditional material the Poynting vector S always forms a right- handed triplet with E and H (S = E Lambda H). In the left handed media, the Poynting vector S and the wave vector K are in opposite directions. Thus, the wave moves in the direction opposite to the direction of the energy flow: phase speed and group speed are anti- parallel. Therefore, a left-handed media is artificial and does not exist in nature. Indeed, when these materials are inserted into a guided wave device, one obtains the backward-wave effect. The goal of this work is to study more in details this physical phenomenon. To undertake this study, this paper presents also the design of a 10 GHz beam-scanning CPW-Antenna fabricated on metamaterial support.
随着被称为“左手材料”(LHM)或“超材料”的材料的出现，物理学出现了一个新的领域。这些材料表现出非常特殊的特性。它们的折射率为负值，这导致了斯涅尔定律的反转。然而，在传统材料中，坡印亭矢量S总是与E和H形成一个右手三重态(S = E λ H)。在左手介质中，坡印亭矢量S和波矢量K方向相反。因此，波的运动方向与能量流的方向相反:相速度和群速度是反平行的。因此，左手介质是人造的，在自然界中不存在。事实上，当这些材料被插入导波装置时，人们就得到了反向波效应。这项工作的目的是更详细地研究这一物理现象。为了进行这项研究，本文还设计了一种基于超材料支撑的10 GHz波束扫描cpw天线。

Security systems for home or industry have a lot to perform today and the data collection and fusion demands careful processing and discerning of security problems. The paper examines signals that are created to perform multiple surveillance systems through a common remotely monitored system. The problems of data detection without errors becomes important to avoid falsely discerning insecurity levels. The paper examines methods for this. Among this is considered the technique for encoding using the Hilbert Transform. This works better with Doppler based security sensors with lesser extra bits of transmission for error free reception at the monitoring computer station.

The autonomous character of mobile ad-hoc networks (MANET) poses significant challenges on network communications. Some of the main challenges in this area related to routing protocols. To make MANETs adaptive to different mobility and traffic patterns, this paper proposes a novel routing scheme which is utilized cross layer design and attempts to develop DSR routing protocol in MANETs with simple node-level management behavior resulting in overall system optimization. We develop a probabilistic multipath routing algorithm and incorporates factors like signal strength into the route metrics so as to predict link breaks before they actually occur. In addition to signal strength and shortest-path metrics, our algorithm updates the goodness of choosing a particular path based on congestion measurement and energy level in each node. By All of the above improvements in conventional DSR, the simulation results testify that our new Robust DSR algorithm can be suitable in ad-hoc situations.

This paper deals with downlink space-frequency block coding (SFBC) with a multi-user pre-filtering technique for MIMO MC-CDMA systems. We consider the use of an antenna array at both the base station (BS) and the user terminal (UT). The space-frequency block codes allow that the spatial diversity be efficiently exploited and the linear multi-user frequency pre-filtering technique modulates the transmitted signal to eliminate the effects of multiple access interference (MAI) and channel distortions at the user terminals. The aim of this technique is to transfer the most computational complexity from UT to the BS, keeping the first one at very low complexity. The performance of the proposed scheme is evaluated, considering typical pedestrian scenario and both uncoded data and channel turbo coding based on UMTS specifications.
