The cooperative communication technology proposed in recent years enables network nodes to share their antennas to achieve diversity gain. In this paper, an efficient variation scheme on opportunistic cooperation is proposed by using an outag

In this paper, we study a decode-and-forward twoway relaying network. We propose an opportunistic two-way relaying (O-TR) scheme based on joint network coding and opportunistic relaying. In the proposed scheme, one single “best relay” is sele

A Vehicular Ad-Hoc Network (VANET) is a network where vehicles can disseminate information such as traffic conditions, availability of free parking lots or content. In order to fulfill VANET application requirements (Time To Live (TTL), informati

In this paper, power control algorithm using Iterative Partitioned Water Filling (IPW) are performed for CR network with multiple PUs and SUs under opportunistic spectrum access mode.
