Live virtual machine migration has become a core system management tool to achieve load balancing and power saving among different servers. The recent studies mainly focus on the performance improvement for live VM migration. However, there has been little attention on the migration's impact on VMs co-located both source and destination servers during the migration. The impact, which is mainly caused...
We propose a `cognitive greedy-backhaul' (CGB) routing metric that associates routing with an appropriate channel assignment scheme to determine cognitive backhaul links. Those backhaul links are established in congested areas where higher capacities are required. CGB forces nodes to select those backhaul links which have higher capacities to reduce the relaying burdens that are caused by nodes hopping...
Multiple co-channel WLAN BSSes (i.e., WLAN cells) overlapping in coverage are generally considered undesirable because members of the OBSSes compete for channel access, which typically increases the contention level of wireless medium access and reduces overall system performance. In this paper, we propose to use channel access throttling (CAT) for managing Wireless LAN radio resources for overlapping...
Equipping wireless nodes with multiple radios can significantly increase the capacity of wireless networks, by making these radios simultaneously transmit over multiple non-overlapping channels. However, due to the limited number of radios and available orthogonal channels, designing efficient channel assignment and scheduling algorithms in such networks is a major challenge. In this paper, we present...
