Large scale monitoring systems require reliable and efficient routing protocols used to overcome the limitations introduced by battery operated embedded devices, among which, energy consumption is considered the main concern. This topic has gained a lot of interest in the last decade. Due to numerous advantages, clustering is becoming more prevalent as a routing technology in WSN. This paper describes...
Once considered a playground for hackers and malicious attacks, wireless networks are fast becoming more secure than their wired counterparts. Developments in micro electro mechanical systems (MEMS) and wireless networks are opening a new domain in networking history. Recent technological advances in wireless networking, IC fabrication and sensor technology have lead to the emergence of millimetre...
The covering problem and node deployment is a fundamental problem in the research of wireless sensor network. The number of nodes and the coverage of a network can directly affect performance and operating costs. For this reason, we propose an EMAC algorithm (Energy Efficient Multi-target Associate Coverage Algorithm). The algorithm uses the correlation between the nodes and dynamic grouping to adjust...
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...
Wireless sensor and actor networks (WSANs) have attracted much attention in the recent years. In WSANs, sensor nodes are in charge of the sensing task, while the actor nodes take actions in response to the sensed phenomena or the detected event. In order to execute the correct operations, the applications typically have to process the data or messages from the different sensors in the same order....
