Abstract— We present an improved thresholding LDPC decoding algorithm which outperforms the Split-Row and original Split-Row Threshold decoders with a small increase in hardware....
The paper addresses the relay node placement problem in two-tiered wireless sensor networks. Given a set of sensor nodes in an Euclidean plane, our objective is to place minimum nu...
In this paper, in order to realize the consecutive long-term operations of sensor networks, we propose a novel sustainable sensor network routing protocol considering easy node ex...
Wireless sensor networks are usually deployed in a way “once deployed, never changed”. The actions of sensor nodes are either pre-scheduled inside chips or triggered to respon...
A strategy for energy saving in wireless sensor networks is to manage the duty cycle of sensors, by dynamically selecting a different set of nodes to be active in every moment. We ...
