The reliability, scalability, and stability of routing schemes are open challenges in highly evolving vehicular ad hoc networks (VANETs). Cluster-based is an efficient solution to cope with the dynamic inconsistent structure VANETs. In this paper, we propose a cluster-based scheme (hereinafter referred as connectivity-based clustering), where link connectivity used metric for cluster formation ...

Clustering is an energy-efficient routing algorithm in a sensor cloud environment (SCE). The clustering nodes communicate with the base station via cluster head (CH), which can be selected based on remaining energy, distance, or distance from neighboring nodes. If CH energy and far away head, then it not selection technique. same applies to other criteria. For selection, single criterion suffic...

Unsupervised competitive learning algorithms for clustering of sensor nodes in wireless sensor networks are evaluated with a large scale data set in this paper. The Centroid Neural Network (CNN) is compared with Fuzzy c-Means (FCM) algorithm in determining cluster heads among given sensor nodes. The cluster heads are combined with Low Energy Adaptive Clustering Hierarchy (LEACH) for minimizing ...

Some of the proposed mobile ad hoc network routing algorithms require maintaining a global network state at each node. The global state is always an approximation of the current network state due to the non-negligible delay of propagating local state. The imprecision of global state information and the high storage and communication overhead make those algorithms do not scale well. In this pape...

Body Sensor Networks (BSN) are an emerging application that places sensors on the human body. Given that a BSN is typically powered by a battery, one of the most critical challenges is how to prolong the lifetime of all sensor nodes. Recently, using clusters to reduce the energy consumption of BSN has shown promising results. One of the important parameters in these cluster-based algorithms is ...
