The key issue in determining the lifetime of wireless sensor network (WSN) is the energy burning up of individual node. The cluster based routing improves the energy usage of WSN compared to other routing approach. In this paper, an effective multi-level cluster algorithm using link correlation is proposed for heterogeneous WSN. The level-k hierarchy with single-hop communication between nodes ...

Underwater Wireless Sensor Network (UWSN) is a particular kind of sensor networks which is characterized by using acoustic channels for communication. UWSN is challenged by great issues specially the energy supply of sensor node which can be wasted rapidly by several factors. The most proposed routing protocols for terrestrial sensor networks are not adequate for UWSN, thus new design of routin...

Wireless Sensor Networks (WSNs) have emerged as an attractive and challenging research field. One of the main challenges lies in the constrained energy resources available to sensor nodes. A possible way to save energy is to use a mobile agent to collect the data moving through the WSN, but this approach increases the messages delivery delay. In this work we propose a Mixed-Integer Linear Progr...

The reliability of wireless sensor networks is significant in certain applications, especially the reliable routing. Most existing routing protocols use multi-paths to improve routing reliability. However, multi-paths waste a large amount of energy to obtain redundancy. This is not an optimal option for sensor nodes with limited energy. In this paper, a novel clustering-based reliable multi-hop...

Wireless Sensor and Actor Networks (WSANs) employ significantly more capable actor nodes that can collect data from sensors and perform application specific actions. To take these actions collaboratively at any spot in the monitored regions, maximal actor coverage along with inter-actor connectivity is desirable. In this paper, we propose a distributed actor positioning and clustering algorithm...

In a wireless sensor networks, there are large numbers of sensor that are used to collect data from the network whenever any event occurs. These sensor nodes are placed at large distance from the base station. The data transmission range of sensor node is limited, so the clusters of sensor nodes are formed with the help of any optimizing algorithm. Genetic algorithm (GA), artificial bee Colony ...

To avoid collisions in cluster tree routing and improve the network performance in IEEE 802.15.4 sensor networks, effective scheduling mechanisms need to be developed. In this study, a multiple cluster tree routing technique along with scheduling, for collision avoidance is proposed. Multiple cluster trees are designed in which the Cluster Heads (CH) are responsible for scheduling. Each CH sche...
