Wireless sensor and actor networks (WSANs) deployed in a harsh environment may suffer simultaneous failures causing the network to be partitioned into disjointed parts. Connectivity restoration of these partitions is a vital issue for the reliability of the network mission. Most of the existing works in the literature mainly focus on restoring network connectivity take into account number of moving...
Clustering routing protocols are more adequate for Wireless Sensor Networks (WSNs) due to the higher energy utilization rate and scalability. However, non-uniform node deployment makes the cluster-based routing protocols less efficient, since the energy consumption of the nodes is more imbalanced. In this paper, an Energy Aware Distributed Clustering using Fuzzy Logic (EADC-FL) routing algorithm is...
Clustering sensor nodes is an effective topology control for increasing network lifetime and scalability. It also, balances the load on the sensor nodes. HEED is a well known distributed clustering protocol that uses both energy and communication cost to elect Cluster Heads (CHs) in a probabilistic way. This paper improves HEED protocol using fuzzy logic and a non probabilistic approach for CH election...
Deterministic deployment of distributed sensor networks (DSNs) is sometimes impractical in situations where a global map of the environment is either unavailable or of little use because the environment is dynamic or hostile. One way to deal with such situations is to randomly scatter sensor nodes in the area of interest. However, the deployment carried out in such a way is generally far from optimal...
In wireless sensor network, it is essential to find effective means for power control of randomly distributed nodes. In this paper, based on diverse receiving QoS parameters, a fuzzy algorithm for peer to peer power control of wireless sensor nodes is proposed. Simulation results show that the proposed algorithm reduces packet error rate (PER) and prolongs survival time of network, compared with fixed...
Adequate coverage is one of the main problems for sensor networks. The effectiveness of distributed wireless sensor networks 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 many working environments, for getting...
