Abstract

In this paper, blackhole attack in mobile adhoc networks have been investigated. Blackhole attack is the attack in which all traffic is redirected to a specific node, which may not forward any traffic to all other nodes. The test-bed is created and system is developed using AODV as a base routing protocol on the network simulator. Various network performance parameters i.e. throughput, packet delivery ratio, collisions etc. are analyzed before and after attack. There are two existing mechanisms: packet based prevention, request based prevention and one hybrid mechanism for preventing blackhole attack is proposed. On implementation of blackhole attack the performance of the network reduces, but after implementation of detection and prevention mechanisms the performance of MANETs improves significantly and results shows that proposed hybrid technique is better than existing techniques.

Keywords

Abstract

WiMax is an acronym meaning Worldwide Interoperability for Microwave Access (WiMax). WiMax based on Wireless Metropolitan Area Networking (WMAN) standards developed by the IEEE 802.16 group. The IEEE 802.16 standard was developed to deliver Non-Line-of-Sight (NLoS) connectivity between a subscriber station and base station with typical cell radius of three to ten kilometres. A frequently IP handover plays very important role to increase the performance of network in WiMax. HMIPv6 (Hierarchical Mobile IPv6) basically reduces the overhead of signalling overhead as well as latency of handoff which is associated with the MIPv6. ALRO(Adaptive Local Route Optimization) technique that implements within the single MAP(Mobility Anchor Point) environment optimizes the route at the SMR predefined threshold value. An enhanced version of ALRO technique implemented with Multiple MAP domain is proposed in this paper. It is found that ALRO scheme implemented in HMIPv6 protocol with the multiple MAP environment improves the network performance as compared to basic ALRO scheme.

Keywords

Abstract

The present article deals with the vision of traditional & modern values in education in India. Indian tradition is a very complex thing and not an articulated or self-consistent or unitary concept, and so are the values incorporated in it. The ideal of education has been very grand, noble and high in ancient India. Its aim, according to Herbert Spencer is the 'training for completeness of life' and the molding of character of men & women for the battle of life. In modern Indian Education thought “Simple living and high thinking” is becoming an outdated nation. Increase in one's needs and desires and the efforts to fulfill them all has become the philosophy of life and education in the modern world. Because of the wave called 'Modernization' many changes occurred in education process. These changes in education process are inevitable. But also it is necessary to consistently comply with the respective culture and tradition and make a substantial connection between what is traditional and what is modern. One should not avoid changes because of tradition & also should not neglect tradition because of modernization. Essential connections should be made in both what is called tradition and what is called modern.

Keywords

Education, Values, Culture, Tradition, Modernization.
