Spectrum sharing in cognitive radio networks is essential to ensure effective communication between secondary users. Game theory is suitable to be applied to the spectrum sharing strategies since it considers strategic interactions between users. There are two types of games based on the ability to communicate between users: cooperative game and non-cooperative game. In this paper, the two spec...

This work presents a novel diffusion based dualphase molecular communication system where the source leverages multiple cooperating nanomachines to improve the end-toend reliability of communication. The Neyman-Pearson Likelihood Ratio Tests are derived for each of the cooperative as well as the destination nanomachines in the presence of multiuser interference. Further, to characterize the per...

Since MANETs are mainly composed of lightight devices with limited capabilities, efficiently manage security is crucial to reduce the performance degradation and resources consumption. In particular, mobile ad hoc networks (MANETs) based on cooperative communication (CC) present significant challenges to security issues, as well as issues of network performance and management. Thus the authenti...

Cooperative Communication, a new research area, has revealed a recent origin in the wireless networks, which combines the link-quality and the broadcasting nature of the wireless channels. It is a pure network layer scheme that can be built on top of the wireless networking equipment. Nodes in the network use a lightweight proactive source routing protocol to determine a list of intermediate no...
