In recent years, wireless sensor networks have drawn great attention. This type of network is composed of a large number of sensor nodes which are able to sense, process and communicate. Besides, they are used in various fields such as emergency relief in disasters, monitoring the environment, military affairs and etc. Sensor nodes collect environmental data by using their sensors and send them...
We propose load balancing scheme for games in wireless sensor networks which is based on allocate load on wireless sensor nodes proportionally to each of the agent’s capacity. This proposed scheme is combined dynamic provisioning algorithm based on greedy graph and useroriented load balancing scheme for maintain of the performance and stability of distributed system in wireless sensor networks.
As the usage and development of wireless sensor networks increases, problems related to these networks are becoming apparent. Dynamic deployment is one of the main topics that directly affects the performance of the wireless sensor networks. In this paper, biogeography-based optimization is applied to the dynamic deployment of static and mobile sensor networks to achieve better performance by t...
SAWN provides a forum for the exchange of ideas and results among industry practitioners and researchers working in the emerging area of self-assembling wireless networks. Original research papers and state-of-the-art surveys were solicited on all aspects of self-assembling wireless networks, including, but not limited to, modeling and optimization of heterogeneous self-assembling wireless netw...
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...
Adequate coverage is one of the main problems for distributed wireless sensor networks and The effectiveness of that highly depends on the sensor deployment scheme. Given a finite number of sensors, optimizing the sensor deployment will provide sufficient sensor coverage and save power of sensors for movement to target location to adequate coverage. In this paper, we apply fuzzy logic system to...
The major challenge faced by wireless sensor networks is security. Because of dynamic and collaborative nature of sensor networks the connected sensor devices makes the network unusable. To solve this issue, a trust model is required to identify malicious, selfish and compromised nodes. It supports the decision making processes in wireless sensor networks such as pre key-distribution, data aggr...
Ad Hoc Wireless sensor networks are used in many domestic and critical applications including military, medical, pervasive and ubiquitous computing. Maintenance of wireless sensor networks is of primary concern. Therefore, fault management techniques are devised to avoid network partitioning. This paper proposes a new scheme for fault management in wireless sensor networks. The new technique is...
