Performance and reliability of content access in mobile networks is conditioned by the number and location of content replicas deployed at the network nodes. Location theory has been the traditional, centralized approach to study content replication: computing the number and placement of replicas in a static network can be cast as a facility location problem. The endeavor of this work is to design a practical solution to the above joint optimization problem that is suitable for mobile wireless… 
Content Replication in Mobile Networks
TLDR
This work designs a practical, distributed solution to content replication that is suitable for dynamic environments and achieves load balancing, and uses local measurements only, which approximates well an optimal solution while being robust against network and demand dynamics.
Distributed Placement of Autonomic Internet Services
TLDR
A distributed service migration heuristic that iteratively solves instances of the 1-median problem pushing progressively the service to more cost-effective locations and demonstrating the effectiveness of the heuristic over synthetic and real-world topologies as well as its advantages against comparable local-search-like migration schemes are proposed.
Multiple allocation p-hub location problem for content placement in VoD services: a differential evolution based approach
TLDR
A differential evolution (DE) based method is proposed to solve the problem of a large database of video files, that are pre-partitioned to multiple segments based on the demand patterns of users, with the objective of minimizing the total routing cost.
Cooperative mechanisms for information dissemination and retrieval in networks with autonomous nodes
TLDR
