Abstract: The use of wireless links makes a Mobile Ad hoc Network(MANET) susceptible to malicious attacks, ranging from passive eavesdropping to active interference. In wired networks an attacker has to pass through a set of firewalls and gateways to access the network. Whereas MANETS does not have firewalls or gateways so attacks can take place from all directions. Every node in a MANET is an autonomous unit in itself and free to move independently. So any node without adequate protection is very much prone to be captured or compromised. Intrusion prevention techniques like encryption and authentication can reduce the risk of intrusion but cannot completely eliminate them so a second level of defense is needed. We propose a new quantitative method of intrusion detection system to detect intrusion in MANETS with mobile nodes. The proposed method is a behavioral anomaly based system which is dynamic, scalable, configurable and robust. For simulating the proposed system we use AODV routing protoco

Abstract: E-learning (electronic learning) is emerging as the new paradigm of modern education. Educational institutions, either willingly or reluctantly, are increasingly embracing e-learning in order to remain competitive and improve their services. Advances in e-learning technologies have initiated significant opportunities and threats to institutions within the education sector. With particular reference to e-learning, the absence of accurate information on the key challenges which influence the implementation of e-learning in developing countries could mislead an institution into implementation failure. The extant research tends to specifically focus on developed countries, with little undertaken in developing countries, especially with regards to the implementation process. Therefore, this study investigates the challenges that hinder the implementation of e-learning in developing countries. It also presents the benefits that have emerged with the implementation of e-learning. The positive
