Traditionally, network-based intrusion detection systems (NIDS) monitor network traffic for signs of malicious activities. However, with the growing use of virtual private networks (VPNs) that encrypt network traffic, the NIDS can no longer analyse the encrypted data. This essentially negates any protection offered by the NIDS. Although the encrypted traffic can be decrypted at a network gateway for...
This paper proposes a novel medium access control scheme for low cost, single-hop wireless networks where the source nodes have a transmitter module but no receiver module and hence they can only transmit data to a sink but cannot receive any control signals, like an ACK or NAK, from any other node. The goal of the proposed scheme is to provide QoS (in terms of packet delivery probability) to the...
In this paper, we propose an anycast mechanism which can adaptively choose the best next-hop to forward packets during the announcement traffic indication map (ATIM) window of multi-channel medium access control (MMAC) protocol. In order to improve the performance of networks by reducing transmission retries and packet drop probabilities, we also propose a multipath extension of AODV routing protocol...
