The above challenges call for a dedicated incentive-based low-overhead allocation scheme for multicast services over wireless relay networks. To this end, we define a maximization problem called Multi-Hop Multicast Maximization (MHMM) in wireless relay networks, where the RSs can act as relays for...
IEEE 802.16j-2009 [9] was proposed for mobile multi-hop relay (MMR) networks. In an MMR network, Mobile Stations (MSs) are allowed to route through intermediate RSs to reach the BS, which differs from the single hop WiMAX topology. The new MMR network architecture imposes a demanding perfo...

China’s energy resource structure is rich in coal but poor in crude oil. For a long time, China has to rely on importing crude oil to meet the domestic demand for liquid fuels (including gasoline, aviation fuel and diesel fuel) and basic

For the secondary networks, we derive the system outage probability and its asymptotic expression at high SNR regime. 3.1 Primary networks: interference probability analysis The interference probability is defined as the probability that the interference from secondary transmitters received at the primary ...
18, 2006, entitled “Interference Management Techniques for Wireless Networks,” hereby incorporated by reference. BACKGROUND Wireless networks, such as 3GPP LTE (3rd Generation Partnership Project Long Term Evolution), IEEE802.16, and wireless local area networks (WLAN) typically communicate via radio...
