Abstract

Segmentation is one of the important steps of character recognition system. It is an important step because inaccurate segmentation of characters will cause errors in the recognition stage. In optical character Recognition (OCR) system the presence of touching characters decreases the accuracy rate of character recognition. Touching of half character or full character with other full character makes the character segmentation very challenging or difficult task. In this paper, the method of segmentation for touching characters of handwritten Punjabi text that is the Gurumukhi script has been proposed. The main purpose of this paper is to provide the new segmentation technique based on clustering technique for touching characters.

Abstract

MANET deals with the wireless links of concern resources. Each device connects using the dynamically configuration in the whole network. To require the more than one hop communicate as intermediate node between source nodes to destination node during the lack of available the transmission range. In the research paper, there is analysis of performance of GRP with proposed algorithm MGRP. The performance analyzed by using OPNET MODELER 14.5" Simulator. The simulation performance parameters are - Packet Dropped, Total Number of Backtracks, Delay, Traffic Sent and Throughput for comparing existing GRP and proposed algorithms MGRP.

Keywords

MANET, GRP, OPNET Modeler 14.5.

Abstract

Networks have flourished due to the advent of new technology. There is a mushroom growth in technology and day to day needs for communication which was never experienced before. A Mobile Ad hoc Network (MANET) is a system of wireless mobile nodes that dynamically self-organize in arbitrary and temporary network topologies. People and vehicles can be internetwork in areas without a preexisting communication infrastructure or when the use of such infrastructure requires wireless extension. Various attacks needed to be detected on order to secure the wireless ad-hoc network. In this paper we are discussing various active attacks.

Abstract

Mobile Ad- hoc Networks (MANETS) consist of mobile nodes that connected through a wireless medium. The nodes communicate with each other without any centralized control. Each node in MANETS acts as host or router in the network. The nodes are free to move randomly. The main types of routing strategies are Proactive, Reactive and Hybrid. Each strategy has various routing protocols. These papers discuss characteristics and performance of AODV, DSR, OLSR and DSDV routing protocol. The basic aim of paper is to choose the best routing protocol to maximize the network performance.

Keywords

AODV, DSR, GRP, OLSR, DSDV, MANET.
