We consider a secure overlay cognitive radio network with an eavesdropper wherein a multi-
antenna secondary transmitter performs transmission in primary spectrum, on the condition …

In this work, we consider the broadcast mechanisms for both reliable links and unreliable
links in the Internet of Things (IoT) networks. Focusing on the minimum transmission …

Broadcast is a fundamental network operation, widely used in wireless networks to
disseminate messages. The energy-efficiency of broadcast is important particularly when …

In this paper, the effectiveness of cooperative broadcast in high-density linear networks is
studied. In the considered protocol, a single source sends messages continuously causing …

In this paper we propose a novel approach for the performance prediction of multistage
cooperative broadcast. It is based on inter-node distance distributions, considers each stage …

Cooperative communication systems are wireless communication systems in which
user/users communicates to a destination via relay/relays. In recent years, cooperative …

Energy consumption is one of the most important considerations when designing routing
and transmission protocols of sensing networks in internet of things. In order to achieve low …

In this thesis low complexity physical layer cooperative communication schemes are
investigated to improve the spectral efficiency, the scalability and the coverage range of …

Energy accumulation is an approach to reducing the power consumption of broadcast. In
conventional approaches, a node can decode the message if the received power from a …
