Wireless communication devices are widely subjected to intruder attacks and in the existing security system, the algorithm consists of a ranging phase that uses the received signal strength to estimate a network radio map and a localization phase which uses a genetic algorithm to obtain the most likely position of the intruder node within the map using the genetic algorithm which is not time consuming...
This paper discusses an energy constrained distributed estimation in wireless sensor network (WSN) based on frequency and time division multiple access (FTDMA). In a measurement with WSN, sensors transmit observed quantized data to a fusion center (FC) via radio communication channels, to obtain a final estimate. Such systems require a multiple access technique such as time division multiple access,...
How to minimize the network redundancy and prolong network life are important problems while designing a coordinated multi-sensors coverage system. By adopting stochastic sensing model for each sensor node, this paper founds an optimization model for coordinated multi-sensors coverage problem. Then an improved genetic algorithm based on parallelism selection is presented. The simulation results show...
Sensor networks have recently emerged as a premier research topic. Sensor networks pose a number of new conceptual and optimization problems. Some, such as location, deployment, and tracking, are fundamental issues, in that many applications rely on them for needed information. While designing the sensor networks according to performed computation, the limited number of sensors to cover an area will...
Energy-saving is one of the inevitable problems of the routing design in wireless sensor networks. The article obtains network routings by genetic algorithm, and the genetic algorithm has been improved by using data fusion and the model of wireless energy transmission. The simulation results show that the improved algorithm has made great progress in balancing the consumption of energy so as to prolong...
Location knowledge of sensor nodes in a network is essential for many tasks such as routing, cooperative sensing, or service delivery in ad hoc, mobile, or sensor networks, and it is hard to get the precision solution by traditional node localization algorithm, while genetic algorithm is an effective methodology for solving combinatorial optimization problems, so, in this paper, a real-coded version...
Wireless mesh networks (WMN) are emerging as an attractive technology for providing broadband connectivity to mobile clients who are just on the edge of wired networks, and also for building self-organized networks in places where wired infrastructures are not available or not deemed to be worth deploying. This paper investigates the joint link scheduling and routing issues involved in the delivery...
The function of neural network of human beings is quite similar to that of the sensor network, which is a cluster of firmly related individual units performing a special function. According to the architecture of neural network, a dynamic-cluster energy-aware routing algorithm (DCEAR) has been proposed in this paper. The nodes on the network have adopted an active routing based on event awaking. Firstly,...
Layout is an important issue in designing sensor networks. This paper brings a new idea for the positioning of nodes in a wireless sensor network. The sensors communicate with each other to transmit their data to a high energy communication node which acts as an interface between data processing unit and sensors. Optimization of sensor locations is essential to provide communication for a longer duration...
