Recently, Network Function Virtualization (NFV) has been proposed to transform from network hardware appliances to software middleboxes. Normally, a demand needs to invoke several Virtual Network Functions (VNFs) in a particular order following the service chain along a routing path. In this paper, we study the joint problem of VNF placement and path(More)
This paper addresses a more reliable and fault-tolerant version of the standard relay placement problem (RPP) in the design and deployment of wireless sensor networks. Given a set of sensors in a Euclidean plane, the 2-connected relay placement problem (2CRPP) is to place minimum number of relays such that each sensor can communicate with at least one(More)
