Multi-level clustering offers the scalability that is essential to large-scale ad hoc and sensor networks in addition to supporting energy-efficient strategies for gathering data. The optimality of a multi-level network largely depends on two design variables: 1) The number of levels, and 2) The number of nodes operating at each level. We characterize these variables within a multi-hop, multi-level...
Various clustering protocols for ad hoc networks have been proposed in order to optimise the networks energy efficiency. These protocols rely on the formation of highly dense clusters which resulted in a large variation of cluster size and thus suffers from a poor load balancing. This paper introduce a novel distributed clustering algorithm using fuzzy logic for the formation of uniform size clusters...
Performance parameters are pretty important as well as clustering and routing algorithm in order for conditioning network lifetime in Wireless Sensor Network (WSN). The parameters like number of nodes, network area and radius of node coverage affects network lifetime directly. In this study the radius of node coverage's effect on network lifetime was checked out on various number of nodes. In the...

As the virtual backbone of the network, connected dominating set (CDS) plays an important role in supporting data communication, reducing the routing overhead, and enhancing the scalability of the network. Traditional CDS construction algorithms are usually applied to the networks with homogeneous nodes, e.g., a pure wireless sensor network. In the past few years, Wireless Sensor and Actor Networks...
Energy utilization has been a major factor in deciding the efficiency of ubiquitous wireless sensor networks. Since most of the wireless nodes are powered by battery an effective algorithm is necessary to use the limited resource effectively. Data collision occurs in Intra-clustered network due to the use of Omni-directional antennas and any introduction of new node in to the network. In this paper,...

So here, we are combining the concept of ferry to the WSN. In general, ferries are small commutator boats which carry or take the peoples from...
Localisation in wireless sensor network is the process of determining the geographical location of the sensor nodes. Conventional localization is space oriented which uses GPS (Global Positioning System) signal to obtain the location information of the nodes. But the GPS signals fail to work in indoor environments, the reason for which it becomes mandatory to opt for terrestrial localisation. The...

Wireless Sensor Networks (WSNs) are increasingly implemented in different area of applications. It is possible that the data collected by adjacent nodes can be redundant due to large numbers of nodes in these networks, so aggregation of data should be exploited for Energy conservation in WSNs. It is very important to transmit the aggregated data to the sink node or base station effectively and reliably...
Based on the Bounded Delaunay Triangulation, Sink nodes' optimal mobile path was designed using Calculating Algorithm of Collecting Blind Area. And there movement is optimized by Hierarchical Clustering Algorithm. Sink nodes' movement is controlled in dominant regions to partially receive information from S nodes, which can reduce the expense of maintenance transmission path, and guarantee the reliability...
Prolonging the network lifetime, scalability and balancing are very important requirements when implementing a wireless sensor network (WSN). Clustering is a technique that has been widely applied for achieving these goals. However, there exists the energy hole problem which causes an unbalanced energy consumption in equally formed clusters. More specifically, nodes near the base station (BS) die...
The energy content in a network mainly depends on the number of clusters and cluster heads. Hence the clustering procedure is very significant towards efficient network resource utilization. The transmission range and layout of the nodes play a very important role in any clustering methodologies. In this paper, a new clustering approach involving transmission range, location of a node in the network...

By reducing the transmission range of the nodes, energy consumed by each node is decreased and topology is formed by sending messages between the nodes such as RTS and CTS. A new algorithm is formulated by deriving a mathematical...
In wireless sensor networks, one of key techniques to save power consumption is a clustering. There are several location based clustering schemes. In these methods, a network area is divided into cells, and one node is selected as a cluster head in each cell. Making all nodes except cluster heads sleep, these methods can save power consumption. However, they can be applied to the static network topology...
