WMSN positioning algorithm based on multi plane antennas

2016 Progress in Electromagnetic Research Symposium (PIERS), 2016
We design a WSN anchor node with multi plane antennas, and study the transmission characters of these antennas, then propose a low complexity positioning algorithm for WSNs especially for WMSNs. Positioning using single anchor node and multi anchor nodes are tested both at last.

Underground WMSN distributed video coding based on HVS

2011 IEEE 3rd International Conference on Communication Software and Networks, 2011
DVC is a suitable code scheme to overcome the limited memory capacity and low power consumption of video sensor nodes in Wireless Multimedia Sensor Network (WMSN). To further improve the coding performance, we propose a distributed video coding (DVC) scheme with the human visual system (HVS) which seldom senses any changes below the just noticeable ...

Efficient algorithms for sensor detachment in WMSNs

International Journal of Ad Hoc and Ubiquitous Computing, 2014
Target coverage is an important issue in wireless sensor networks (WSNs). This work copes with the target coverage problem which detaches a set of mobile sensors to targets efficiently. Given a set of disconnected targets with different quality of monitoring (QoM) and a set of mobile sensors which are distributed randomly in the networks, this paper ...

An efficient transmitting strategy for image fusion in WMSN

2015 IEEE International Conference on Communications (ICC), 2015
Wireless Multimedia Sensors Networks are characterized by a high consumption of network resources such as energy and bandwidth. This consumption is caused by the large amount of data flowing across the network. One of the mechanisms used to reduce the consumption of resources is data fusion to eliminate redundant transmission while synthesizing the ...

The WMSN Routing Protocol Based on Multiple QoS Constraints

Applied Mechanics and Materials, 2012
In order to satisfy the data transmission in the wireless sensor multimedia network of several QoS constraints. This paper proposes a real-time and low energy consumption routing protocol on the basis of MMSPEED, This agreement inherits the advantages of MMSPEED protocol, multipath and priority classification data transmission. And at the same time, in
