Abstract: |
Generic
Network Location Service provides a Location Service system based on DHT
technology, which is storing device location records in nodes within a Chord
DHT. Location records are consisting of network device identification keys as
attributes, which are used to create replicas of additional location records
through established hashing mechanisms. Specifically, we first discuss the
design of an alternative approach to address translations based on DHT usage
then report how fault-tolerance can be ensured through replication strategies
namely proactive and reactive. As a result, we show how the record is stored
in more copies and each copy provides access to others, allowing us to create
efficient update and recovery mechanisms. Storing collections of network
device identifications has some advantages: straightforward implementation of
all possible translations at the same time (provides efficient discovery
mechanisms for location services which are unavailable in current systems),
and fault-tolerance to DHT's node and network failures due to inherent
replication of identification records. |
