MicroOpt: Model-driven Slice Resource Optimization in 5G and Beyond Networks
Muhammad Sulaiman, Mahdieh Ahmadi, Bo Sun +4
A pivotal attribute of 5G networks is their capability to cater to diverse application requirements. This is achieved by creating logically isolated virtual networks, or slices, wi…
Optimal Service Placement, Request Routing and CPU Sizing in Cooperative Mobile Edge Computing Networks for Delay-Sensitive Applications
Naeimeh Omidvar, Mahdieh Ahmadi, Seyed Mohammad Hosseini
We study joint optimization of service placement, request routing, and CPU sizing in a cooperative MEC system. The problem is considered from the perspective of the service provide…
Generalizable Resource Scaling of 5G Slices using Constrained Reinforcement Learning
Muhammad Sulaiman, Mahdieh Ahmadi, Mohammad A. Salahuddin +2
Network slicing is a key enabler for 5G to support various applications. Slices requested by service providers (SPs) have heterogeneous quality of service (QoS) requirements, such…
Cache Subsidies for an Optimal Memory for Bandwidth Tradeoff in the Access Network
Mahdieh Ahmadi, James Roberts, Emilio Leonardi +1
While the cost of the access network could be considerably reduced by the use of caching, this is not currently happening because content providers (CPs), who alone have the detail…
Impact of Traffic Characteristics on Request Aggregation in an NDN Router
Mahdieh Ahmadi, James Roberts, Emilio Leonardi +1
The paper revisits the performance evaluation of caching in a Named Data Networking (NDN) router where the content store (CS) is supplemented by a pending interest table (PIT). The…
