By decoupling the control plane from the data plane and providing programmability for network applications, software-defined network (SDN) is positioned to offer more efficient management, higher flexibility and better performance. Routing and resource allocation are two closely related applications in wireless networks. With close cooperation, better performance and lower complexity can be achieved...
MAC interference in IEEE 802.11 network is caused by overlapped signal ranges and complex carrier sensing topology. Data throughput and wireless coverage increases by sender's transmission power in free space and this property identified the transmission power as a standard indication for wireless efficiency; however, increased transmission power also implies longer reachable signal range and higher...
3GPP LTE-Advanced has recently been investigating heterogeneous network (HetNet) deployments as a cost effective way to deal with the unrelenting traffic demand. HetNets consist of a mix of macrocells, remote radio heads, and low-power nodes such as picocells, femtocells, and relays. Leveraging network topology, increasing the proximity between the access network and the end users, has the potential...
