Wireless sensor networks (WSNs) contain numerous sensors. These sensors communicate with a vast number of small nodes via radio links. Therefore, WSNs have the most security attacks cause the limited cpacity of sensor nodes. The security attacks impact to many applications ...

Sensor applications in medical instrumentation measurement are very extensive, but mostly the input and output of the sensor is nonlinear, which brings a great inconvenience for the measure of medical instruments. This paper introduces biological immune system on the basis of the evolution planning, thereby forming immunization programs to use non-linear calibration of the sensor. This method j...

Positioning service is one of Wireless Sensor Networks’ (WSNs) fundamental services. The accurate position of the sensor nodes plays a vital role in many applications of WSNs. In this paper, a 3D positioning algorithm is being proposed, using mobile anchor node to assist sensor nodes in order to estimate their positions in a 3D geospatial environment. However, mobile anchor node’s 3D path optim...

mobile sensor networks rely heavily on inter-sensor connectivity for collection of data. nodes in these networks monitor different regions of an area of interest and collectively present a global overview of some monitored activities or phenomena. a failure of a sensor leads to loss of connectivity and may cause partitioning of the network into disjoint segments. a number of approaches have bee...

an efficient cluster head selection algorithm in wireless sensor networks is proposed in this paper. the implementation of the proposed algorithm can improve energy which allows the structured representation of a network topology. according to the residual energy, number of the neighbors, and the centrality of each node, the algorithm uses fuzzy inference systems to select cluster head. the alg...

Wireless smart sensor networks (WSSNs) have been expected to improve the capability to capture structural dynamic behaviors through dense instrumentation as well as to evaluate the current condition of structures. While the expectation for structural health monitoring using WSSNs has been high, among the key limitations are the limited radio communication range and communication speed. A multih...
