Paper Abstract
Unattended ground sensor systems (UGS) have become an important part of a covert monitoring arsenal in operations
throughout the world. With the increased use of unattended ground sensor systems, there is a need to develop
communication architectures that allow the systems to have simple emplacement procedures, have a long mission life,
and be difficult to detect. Current ad-hoc networking schemes use either a network beacon, extensive preambles, or
guaranteed time synchronization to achieve reliable communications. When used in wireless sensor systems many of
these schemes waste power through unnecessary transmissions. These schemes compromise the covert nature of UGS
through excess transmissions for a non-beaconed network or the periodic beaconing in a beaconed network. These
factors are detrimental to sensor systems, which chiefly rely on being covert and low-power. This paper discusses a nonarbitrated,
non-GPS synchronized, beaconless approach to discovering, joining, and reliably transmitting and receiving
in a low-power ad-hoc wireless sensor network. This solution is capable of performing network discovery upon demand
to get an initial alignment with other nodes in the network. Once aligned, end points maintain alignment and can predict
when other nodes will be available to listen.
