in wireless sensor networks, optimal consumptionof energy and having maximum life time are important factors. in this article attempt has been made to send the data packets with particular reliability from the beginning based on aodv protocol. in this way two new fields add to the routing packets and during routing and discovering of new routes, the lowest remained energy of nodes and route tra...

in this paper, we propose a scheme to improve existing ad-hoc on-demanddistance vector (aodv) routing protocol by discovering and maintaining multiplenon-overlapped routes. our routing protocol is a multipath version of aodvrouting protocol that considers only the disjoint path. due to non-overlappingamong paths, when a link breaks in the network, only one of paths is expired. thepresented rout...

The misclassification error which is usually used in tests to compare classification algorithms, does not make a distinction between the sources of error, namely, false positives and false negatives. Instead of summing these in a single number, we propose to collect multivariate statistics and use multivariate tests on them. Information retrieval uses the measures of precision and recall, and s...

The issue of formal thought is addressed, a Piagetian theme that has not lost its validity. objectives this work are: (a) To study the psychometric properties an instrument for evaluation operative performance elaborated ad hoc from Longeot (TOFLP) and Flexer Roberge (FORT) tests; (b) Verify order acquisition operations evaluated in proposed instrument. A scalographic analysis items (Guttman te...

This paper details a hardware implementation of distributed Θ(1) time algorithm allows to select dynamically the master device in ad-hoc or cluster-based networks constant regardless number devices same cluster. The each automatically detect its own status; slave; based on identifier without adding extra overheads exchanging packets that slow down network. We propose baseband design implements ...

This article describes an implementation of automation system for engines that uses the ESP- NOW and MQTT (Message Queue Telemetry Transport) protocols to send data. The main created is avoid loss due eventual objective in communication data network. For this, developed can use two network topologies: Mesh Ad Hoc. As a form control, they were performed control water system, where run-level was ...
