Wireless sensor networks (WSNs) have gained worldwide attention in recent years. Since WSNs can be conveniently deployed to monitor a given field of interest, they have been considered as a great long-term economic potential for military, environmental, and scientific applications and so forth. One of the most active areas of research in WSNs is the coverage which is one of the most essential functions to guarantee quality of service (QoS) in WSNs. However, less attention is paid on the heterogeneity of the node and the energy balance of the whole network during the redeployment process. In this work, the energy balanced problems in mobile heterogeneous WSNs redeployment have been analyzed. The virtual force algorithm with extended virtual force model is used to improve the QoS of the deployment. Furthermore energy model is added to enhance or limit the movement of the nodes so that the energy of nodes in the whole WSNs can be balanced and the lifetime of the networks can be prolonged. The simulation results verify the effectiveness of this proposed algorithm.

Intrusion detection in Wireless Sensor Network (WSN) is of practical interest in many applications such as detecting an intruder in a battlefield. The intrusion detection is defined as a mechanism for a WSN to detect the existence of inappropriate, incorrect, or anomalous moving attackers. In this paper, we consider this issue according to heterogeneous WSN models. Furthermore, we consider two sensing detection models: single-sensing detection and multiple-sensing detection... Our simulation results show the advantage of multiple sensor heterogeneous WSNs.

Full Benefit

While wireless sensor networks are increasingly equipped to handle more complicated functions, these battery poweredsensors which used in network processing, use their constrained energy to enhance the lifetime of the network especially in a heterogeneous settings. Clustered techniques have since been employed to optimize energy consumption in this energy constrained wireless sensor networks. In Classical clustering protocols, equal energy is assigned to all nodes andthey cannot take full benefit of the presence of node heterogeneity. SEP, a heterogeneous-aware protocol is used to prolong the time interval before the death of the first node which is crucial for many applications where the feedback fromthe sensor network must be reliable. The performance of SEP in comparison to LEACH Protocol is analyzed in this paperwhose goal is to increase the stable region and as a result decrease the unstable region and improve the quality of thefeedback of wireless sensor network, in presence of heterogeneous nodes.

Simulation Results

The research on wireless sensor networks has achieved a lot in recent years and some of the results have been put into practical applications, but with the increasing demand and requirements for wireless sensor networks, many old and new problems need to be solved urgently. In this paper, a data topology optimization algorithm based on local tree reconstruction for heterogeneous wireless sensor networks is proposed for data transmission in wireless sensor networks that are easily affected by external instabilities. This heterogeneous network can accomplish better data transmission; firstly, the nodes are divided into different layers according to the hop count of nodes in the network, and a certain proportion of relay nodes are selected for different layer nodes; then, different initial energy is set for different layer nodes, and since the data packets of different nodes have different sizes, the corresponding data aggregation coefficients are used in this paper according to the actual data requirements of the network during data transmission; finally, the topology of the tree is dynamically updated in real time during the operation of the network to extend the lifetime of the nodes. The simulation results verify that the proposed heterogeneous network topology evolution algorithm effectively extends the network lifetime and improves the utilization of nodes. This paper establishes a modified least-squares target localization model to achieve accurate 3D localization of targets in real scenes and proposes an optimal base station node selection strategy based on spectral clustering using the location distribution information of base station nodes in space. The simulation results show that the error of the terminal 3D coordinates calculated by the proposed algorithm is smaller than the real coordinates, and the error is smaller than other existing algorithms with the same simulation data.

Simulation Results

Virtualization  of  Wireless  Sensor  Networks (WSN)  is  a  new  concept  that  can  provide  a  common platform  upon  which  new  federated  sensor architectures can be built, experimented and evaluated. A  Virtualized  Sensor  Network  (VSN)  is  formed  by  a subset  of  sensor  nodes  of  a  physical  WSN  that  is dedicated to a certain task or an application at a given time.  In  this  paper,  we  investigate  the  requirements that virtualization imposes on the routing procedure of the  involved  WSNs  and  propose  a  routing  scheme: Virtualized-EMRP  (based  on  EMRP  [1]).  In  addition, over the same WSN, different applications may require different  QoS  levels  but  satisfying  this  is  not  always  a straightforward  task.  In  the  context  of  VSN,  this  task can  be  resolved  by  initializing  different  instances  of Virtualization-EMRP  routing  protocol  and  adjusting its  routing  metrics.  We  use  OMNET++  simulator  for different  scenarios  of  Virtualized-EMRP  associated with  different  routing  metrics  and  simulation  results show that QoS differentiation for different applications can be achieved.
