We consider the problem of cross-layer resource allocation in time-varying cellular wireless networks, and incorporate information theoretic secrecy as a Quality of Service constraint. Specifically, each node in the network injects two types of traffic, private and open, at rates chosen in order to maximize a global utility function, subject to network stability and secrecy constraints. The secrecy...
Security in mobile ad hoc networks (MANET) Quality of Services routing has received increased attention in recent years. This paper proposes mechanism to obtain secure MANET QoS routing with regard to QoS considerations. Our goal is to present a new mechanism over on-demand multi-path routing protocol (AOMDV) that tackles the twin issues of reliability (protection against failures of multiple paths)...
There have been several approaches to provisioning traffic between core network nodes in Internet Service Provider networks. Such approaches aim to minimize network delay, increase capacity, and enhance security services. MATE (Multipath Adaptive Traffic Engineering) has been proposed for multipath adaptive traffic engineering between an ingress node (source) and an egress node (destination). Its...

In spite of their potential to improve the performance of wireless communication systems, relay-based communication systems face significant challenges, resource wastage. In this article we discuss resource efficiency in relay systems, particularly in two-way and full-duplex relay systems that utilize multiple antennas and improved duplexing to enhance system efficiency. We compare in detail the features,...

Covert channels are used to secretly transfer information. Due to the widely existence of network protocols, encoding covert channels into computer network protocols is highly applicable. The jitter field of RTCP header possesses a characteristic that could be used to set up covert channels. Thus, in this paper, a novel covert channel on jitter field is proposed. In order to set up this channel, statistical...
