Abstract:
|
The positioning ability is essential in mobile networks.
Providing the position of entities is in general a complex task that
becomes especially hard in ad hoc networks. In these networks,
the topology cannot be planned and network nodes usually
present restrictions in terms of computation capabilities and
autonomy that constrain the network lifetime. Passive algorithms
have been proposed for minimizing the impact of location
services in the network, i.e. reducing the location traffic and
extending the network life. However, the accuracy of passive
algorithms tends to be worse than the accuracy for active
approaches. This paper studies the impact of several proposals
focused on improving the accuracy of the passive TDOA
algorithm. Results indicate that weighing the ordinary least
squares algorithm with the appropriate factors could be enough
for improving the accuracy of the algorithm in some scenarios. |
