In recent developments, regulatory bodies are introducing flexible use of spectrum such as allowing the use of temporarily unoccupied VHF and UHF bands also known as television white spaces (TVWS). The networks exploiting such opportunity, hereafter called opportunistic networks, have equal right to access available TVWS. As a result, unhealthy competition to occupy the same spectrum would be inevitable...
In this paper, we address the following two types of coexistence between wireless networks: 1) coexistence among secondary user (SU) networks and 2) coexistence between primary user (PU) and SU networks. The former type addresses the sharing of a common spectrum opportunity among SU networks to achieve an efficient spectrum usage, whereas the latter type addresses the interference from SUs to PUs...
TV White Spaces (TVWS) refer to segments of the TV spectrum not used by licensed users in a given location. In recent years, regulation agencies throughout the world consider the possibility to open TVWS to unlicensed use, which is followed by standardization activities to realize it. One of the important aspects of unlicensed operation in TVWS is coexistence between heterogenous networks. This paper...
