Follow the Leader: a Scalable Approach for Realistic Group Behavior of Roaming NPCs in MMO Games

Dario Maggiorini, Laura Ripamonti, Samuele Panzeri
2013 Advances in Artificial Life, ECAL 2013  
This paper addresses the problem of defining a smart, more challenging, and natural movement model for NPCs.  ...  Unfortunately, standard NPCs behavior, i.e., patrolling between rally points, does not put a significant challenge to players once its deterministic movement pattern is discovered.  ...  In particular, mobs (shorthand for "mobiles") are NPCs roaming the map and typically implement monsters to be defeated or avoided.  ...

P4G2Go: A Privacy-Preserving Scheme for Roaming Energy Consumers of the Smart Grid-to-Go

Aristeidis Farao, Eleni Veroni, Christoforos Ntantogian, Christos Xenakis
2021 Sensors  
This paper presents P4G2Go, a novel privacy-preserving scheme that provides strong security and privacy assertions for roaming consumers against honest but curious entities of the smart grid.  ...  One such example is when a landlord rents their property for a specific period to tenants. Then the electricity bill could be redirected from the landlord's utility to the tenant's utility.  ...  In the latter case, a mobile user wants to access the roaming network and get charged by their home operator.  ...
