Vehicular Ad-hoc Network (VANETs) is the specific form of Mobile ad-hoc networking (MANETs) in which high dynamic nodes are utilized in carrying out the operations. They are mainly used in urban areas for safety traveling. Clustering algorithms are used for clustering the vehicles that are in the range of the network as VANET consists of a great amount of traffic. A clustering head node is used...

The nodes in the mobile ad hoc networks act as router and host, the routing protocol is the primary issue and has to be supported before any applications can be deployed for mobile ad hoc networks. In recent many research protocols are proposed for finding an efficient route between the nodes. But most of the protocol’s that uses conventional techniques in routing; CBRP is a routing protocol th...

In recent years, the applications of Wireless Sensor Networks (WSNs) have grown enormously. In WSNs there is one mechanism used to enlarge the lifespan of network and provide more efficient functioning procedures that is clustering. Clustering is a process to subdivide the sensing field of sensor network into number of clusters. Each cluster selects a leader called cluster head. A cluster head ...

Hierarchical Clustering is a procedure of cluster analysis which aims to construct a hierarchy of clusters. There are two kinds of hierarchical clustering i.e. Agglomerative, which is a bottom – up approach, where all the observations start in its own cluster, and pairs of clusters are merged moving up the hierarchy, and the other one is divisive, which is a top down approach, where each observ...

Sensor networks supported by recent technological advances in low power wireless communications along with silicon integration of various functionalities are emerging as a critically important computer class that enable novel and low cost applications. There are many fundamental problems that Wireless Sensor Networks (WSNs) research will have to address in order to ensure a reasonable degree of...

Because of the influence of energy consumption of wireless sensor network, the location information of nodes in wireless sensor networks is very important, the current general localization algorithm is not suitable for harsh environment. This paper proposes a scheme based on the ranging node localization to improve the overall performance of the network. The routing algorithm is designed to dir...

This research paper has focused on evaluating the performance of the heterogeneous WSNs using fuzzy based cluster head selection and the tradition EDDEEC protocols. The EDDEEC has used different probability function for choosing the best cluster head by using the remaining energy and average energy of the network. But EDDEEC has neglected the use of number of neighbours of sensor nodes during c...

One of the most important consideration in designing sensor nodes in a wireless sensor network for prolonging the network lifetime by minimizing energy consumption. The number of cluster and the distribution of cluster heads (CHs) always make a major impact on the network performance. Distance and Density based clustering algorithm can greatly improve energy efficiency of WSNs because it adopts...

Energy-constrained wireless sensor network (WSN) has attained considerable research attention in recent years and requires robust and energy efficient routing protocols for communication in fading environments to minimise the energy consumption.To Mitigate the Fading Effect in Wireless Channel ,MultiInput Multi Output(MIMO)Scheme is Utilized for Wireless Sensor Network. This Paper proposed a Cl...
