Abstract

Network technology smooth the progress of communication system in a sophisticated manner at the same time it braves are increased from the huntsman. In communication process, user’s connectivity, violations of policy on access of information are handles through intrusion. Intrusion prevention is the process of performing intrusion detection and attempting to stop detected possible incidents. It focused on identifying possible incidents, logging information about them, attempting to stop them, and reporting them to security administrators. However, organizations use Intrusion detection and prevention system (IDPS) for other purposes, such as identifying problems with security policies, documenting existing threats, and deterring individuals from violating security policies. Now a days IDPSs have become a necessary addition to the security infrastructure of nearly every organization. In this paper describes about Simple Network Management Protocol Application Level Gateway (SNMP ALG) protocol sequences which is used to detect the intrusion on hybrid network and its attributes and recommend the standardized (SNMP ALG) protocol for the intrusion detection process

Abstract

Clustering is a process of discovering groups of objects such that the objects of the same group are similar, and objects belonging to different groups are dissimilar. A number of clustering algorithms exist that can solve the problem of clustering, but most of them are very sensitive to their input parameters. Therefore it is very important to evaluate the result of them. The minimum spanning tree clustering algorithm is capable of detecting clusters with irregular boundaries. In this paper we propose a minimum spanning tree based clustering algorithm with cluster evaluation. The algorithm produces k clusters with center and guaranteed intra-cluster similarity. The radius and diameter of the k clusters are computed to find the tightness of the k clusters. The variance of the k clusters is also computed to find the compactness of the clusters. In this paper we computed tightness and compactness of clusters, which reflects good measure of the efficacy of clustering.

Abstract

CDMA cellular networks support soft handover, which guarantees the continuity of wireless services and enhanced communication quality. Cellular networks performance depends upon Soft handover parameters. In this paper, we have shown the effect of soft handover parameters on the performance of CDMA cellular networks. We consider HYST_ ADD and HYST_ DROP as the Soft handover parameters. A very useful statistical measure for characterizing the performance of CDMA cellular system is the mean active set size and soft handover region. It is shown through numerical results that above parameters have decisive effect on mean active set size and soft handover region and hence on the overall performance of the soft handover algorithm.

Abstract

In recent years, great interest was focused on microstrip antennas for their small volumes, low profiles, good integration, low costs and good performance. With the continuous growth of wireless communication service and the constant miniaturization of communication equipment, there are higher and higher demands for the volume of antennas, integration and working band. This paper presents A circular polarized (CP) Circular microstrip antenna with triple band for wireless communications system application which are suitable for the 2.4-GHz, 3.5-GHz and the 5-GHz triple-band operations. These systems may include various combinations of Bluetooth, WiMAX (Worldwide Interoperability for Microwave Access) and wireless local-area network (WLAN). A circular microstrip patch antenna is designed to operate at 2.4 (GHz) with circular polarization, a U slot is inserted thereafter in the original patch to generate the second resonant at 5.2 (GHz). Another C-slot is inserted thereafter to generate the 3.5 (GHz) third band. The C slot insertion effect on the original patch is examined, first arc length effect on the return loss and axial ration is examined in order to get the optimum length, and then the arc orientation effect also is examined to find out the best orientation to place the arc. This design has several advantages as the total antenna volume can be reused, and therefore the overall antenna will be compact. The design is verified through both numerical simulations and measurement of a fabricated prototype. The results confirm good performance of the single and multiband antenna design.

Abstract

Mobile Ad hoc NET work (MANET) is a self configuring network of mobile routers (and associated hosts) connected by wireless links – the union of which forms an arbitrary topology. The routers are free to move randomly and organize themselves arbitrarily, thus the wireless network topology may change rapidly and unpredictably. Such a network may operate in larger Internet. There are various routing protocols available for MANETs. The most popular ones are DSR, AODV and DSDV. This paper examines two routing protocols for mobile ad hoc networks– the Destination Sequenced Distance Vector (DSDV), the table- driven protocol and the Ad hoc On- Demand Distance Vector routing (AODV), evaluates both protocols based on packet delivery ratio and average delay while varying number of sources and pause time.

Abstract

A novel technique for obtaining a single-layer single-feed dual frequency rectangular microstrip antenna with protruding semi ellipse for s-band communication is proposed and demonstrated. By protruding semi ellipse of appropriate dimension close to one of the edge, the rectangular patch has been shown to realize dual-frequency broadside radiations. This dual frequency operation increases its applications in radar and space communications. The range of the frequency ratio (FR) can be varied from 1.03 to 1.30 by changing the dimension of semi minor axis of protruding semi ellipse. Several optimizations are performed to attain the optimum values of the antenna physical parameters and then a prototype is fabricated. The presented antenna is compact having an area reduction greater than 15% and shows enhanced radiation characteristics compared to the standard rectangular patch. Details of the antenna design and experimental results are presented.

Abstract

The increasing number of objects 3D are available on the Internet or in specialized databases and require the establishment of methods to develop description and recognition techniques[1,2,3] to access intelligently to the contents of these objects .
In this context, our work whose objective is to present the methods of description and recognizing of 3D objects are based on neural networks and principal component analysis. In fact, it consists of determining invariant descriptors[4,5] and recognizing the objects of a database similar to a given object (query object) using neural networks , descriptor vectors extracted from the principal component analysis and concluded equations from the same analysis and neural networks. The 3D objects of this database are transformations of 3D objects by one element of the overall transformation. The set of transformations considered in this work is the general affine group. The measure of similarity between two descriptor vector objects is achieved by a similarity function using the euclidean distance.
