One of the important applications of wireless sensor networks is in supervision systems in which the information of locations under the supervision of sensors is sent continuously to applicants. Due to the limitation of energy source in sensor nodes, designing the methods based on optimal consumption of energy in wireless sensor networks is of great importance. In this paper, based on query shared...
In this article we applied modified binary particle swarm optimization algorithm for solving the sensor placement in distributed sensor networks. PSO is a real value algorithm, and the discrete PSO is proposed to be adapted to discrete binary space. In the distributed sensor networks, the sensor placement is NP-complete for arbitrary sensor fields and it is one of the most important issues in the...
This article aims to deal with the purposeful election of the cluster head(Leader) in the Wireless Sensor Networks (WSNs). The basic protocol to choose the cluster head(CH) in such networks is LEACH (low-energy adaptive clustering hierarchy) which somehow will realize the election of CH in the network and needs no program for full coverage of the CH. This article by introducing a new protocol called...
Recently, the authors proposed a distributed dynamic route guidance system called UTOSPF (Urban Traffic Open Shortest Path First) based on Wireless Sensor Networks (WSNs) and Open Shortest Path First (OSPF) protocol. In UTOSPF, the routes will be found only based on Estimated Street Travel Times (ESTTs) which will be needed to pass the streets and regardless of Waiting Times for Green Light (WTGLs)...
In this paper, we propose an approach for routing in SPEED protocol considering residual energy in routing decisions. Due to the limited energy of a sensor node, energy-efficient routing is a very important issue in sensor networks. This approach finds energy-efficient paths for delay-constrained data in real-time traffic. The SPEED protocol does not consider any energy metric in its routing. In our...
In this article the LEACH (low energy adaptive clustering hierarchy) in the homogeneous wireless sensor networks (WSNs) was considered and a new protocol with an approach toward promoting LEACH was introduced. In the new protocol which is called LELE (leader election with load balancing energy), the major work was how to elect the leader which was done through changing the sensor's energy, LELE protocol...
Recent advancements in wireless communications and electronics have caused the emergence of a new type of networks called Wireless Sensor Networks (WSNs). WSNs have some unique features such as autonomy, low cost, tiny size, simple and fast deployment and high scalability, and many applications have been forecasted for them. In recent years, many WSN-based applications were proposed for Intelligent...
