Due to the limitation, such as low computation, low calculation and limited energy, wireless sensor networks (WSN) usually have some vulnerabilities, such as data overflow, 0-divides etc. This paper designed a MAC Layer Tester (called MLT) based on fuzz and border conditions algorithm to detect vulnerabilities according to IEEE 802.15.4. MLT can test protocols stack for IEEE 802.15.4, such as ZigBee...
In view of the wireless sensor network routing LEACH protocol ignored the election of cluster head nodes energy, node density and relative information of base station location, proposes a improved clustering routing algorithm based on energy, density and location information of Sink. Introduces the residual energy and density factors in the threshold formula, makes the cluster heads for the entire...
ZACA-EEC (Zigbee Ant Colony Algorithm Energy Efficient Cluster) routing protocol is proposed to replace AODV in Zigbee with the aim of increasing reliability for mine equipment monitoring in this paper, which can prolong the lifetime of network remarkably. Taking hydraulic support as an example, the distribution of monitoring nodes can be simplified as chain hierarchy topology, then Free-space model...
To solve high real-time and complexity calculation problems such as feature extraction and pattern classification when wireless sensor network real-time diagnosis and equipment health record of the mine coal underground equipments monitoring, this paper purpose a optimal algorithm for task scheduling underground wireless monitoring network based on distributed computing, this method use the fast convergence...
This article puts forward a method to access the data and analyzed results from the monitoring system of environment based on WSN with the B/S mode. It resolves the problem of low speed of page refresh with Ajax. The experiment shows that the partial refresh feature of Ajax can make it possible for the users to get access to the data and analyzed results easily through the browser, and experience...
