Software and Hardware Implementation of Local Intrusion Detection Strategy

Abstract

A mobile ad hoc network (MANET) has many undesirable challenges, black hole (BH) is one of the most significant challenges in MANET. Many researchers have proposed researches which depend on different strategies to face this challenge. The problem is how much the ability of these strategies to detect and block BH in order to empty the network from the threats, and how much these solutions could be implemented practically to treat with threats. However, the required strategy should also maintain network performance at the same time. The idea of this research has been applied on AODV based MANET, the strategy deals with cooperative black hole by using a deceptive message with virtual address that is not in the addresses range [1]. The main interest in this paper beside proposing the new idea, is to convert this idea into strategy by providing the necessary details, in addition to implement the strategy by hardware and software models. These models have been built in order to illustrate how black hole works and how the strategy can detect and block the black hole practically in AODV based MANET. This paper presents the method in an integrated manner. In this method, the detection process starts from the previous node, not from the source node. However, this method can choose the shortest path and can deal with more than one black hole. These additions will preserve the performance of network, the hardware model has been provided with liquid crystal displays LCD put on each node. LCD is used to appear each step, and to make the system full-acknowledgment.
