Abstract: Ad hoc networks are widely researched and applied on various fields. To implement Ad Hoc Networks, the IEEE 802.11 standard Medium Access Control(MAC) protocol are widely applied. However, there are some problems which decrease the transmission efficiency of wireless networks at the standard MAC layer. The standard use 4-way handshake procedure(RTS/CTS/DATA/ACK) to overcome the MAC layer problems. But some problemscannot be solved if only a single channel is used in MAC Layer. Therefore, many multi-channel based MAC protocols were proposed to prevent MAC layer problems. But, those scheme either cannot solve MAC layer problems perfectly. This paper proposes New Dual Channel based Medium Access Control(NDCMAC) protocol for ad hoc networks. This protocol requests just one additional channel and perfectly solves most of MAC layer related problems. For this scheme, busy tone and Negative ACK(NACK) concepts are applied. Using NDCMAC, the channel utilization is significantly increased. Result

Abstract: Intrusion Detection System (IDS) that turns to be a vital component to secure the network. The lack of regular updation, less capability to detect unknown attacks, high non adaptable false alarm rate, more consumption of network resources etc., makes IDS to compromise. This paper aims to classify the NSL-KDD dataset with respect to their metric data by using the best six data mining classification algorithms like J48, ID3, CART, Bayes Net, Naïve Bayes and SVM to find which algorithm will be able to offer more testing accuracy. NSL-KDD dataset has solved some of the inherent limitations of the available KDD’99 dataset.
