Arbitrary Physical Node
    • Essentially a dummy node
    • More Utility, Higher Cost
     • Create hierarchy, obfuscate location information, addition to TAP 
      countermeasures, increase cost of specific atacks
    Project Goals
    • Original Project Goal was to focus on increasing resilience to traffic 
     analysis
      • One of the first thing most anonymous routing protocols covered for a 
      MANET was TA resilience
     Project Goals- Issues with Original 
     Goal
     • Left is before adding a dummy node
       • Thought was key node placement, would help create a network topology closer to what the neutral 
        matrix assumed
         • Hugely important because an atacker can derive physical locations and predict movements via traffic analysis
       •  Location privacy is one of the first things most anonymous routing protocols handle
         • Done via location unlinkability
         • Completely hiding location information
     Project Goals
     • Original Project Goal was to focus on increasing resilience to traffic 
      analysis
       • One of the first thing most anonymous routing protocols covered for a 
        MANET was TA resilience
     • Evolved Goals
       • Analyze popular routing protocols used in MANETs
       • Design solutions using APNs to strengthen the network
         • Cannot be something that is already solved via changes or updates to the routing 
          protocol
           • Reason being is APNs are awkward to implement, and updating the protocol is likely cheaper
    Arbitrary Physical Node
    • Several different set ups
     • Small network of them
     • Multiple nodes scatered throughout MANET
     • Single node
     • Single node
    • Some may also have specialized antenna or algorithms not completely 
     following the routing protocol
    • Many cases this is simply analyzing what it would be like to get closer 
     to an ideal network topology
