This paper proposes a Connected Dominating Set (CDS) based clustering algorithm to prevent the broadcast storm problem in Vehicular Ad-hoc Networks (VANETs). The proposed algorithm accounts for the mobility and degrees of vehicles, and matches the highly dynamic nature of VANETs. VANETs are infrastructure less multihop wireless networks.

A smartphone is a mobile phone built on a mobile operating system, with more advanced computing capability and connectivity than a feature phone. The mobile operating systems (OS) used by modern smartphones are too diverse such as Google's Android, Apple's iOS, Microsoft's Windows Phone, and so on. Such operating systems can be installed on many different(More)
SUMMARY An important objective of surveillance sensor networks is to effectively monitor the environment, and detect, localize, and classify targets of interest. The optimal sensor placement enables us to minimize manpower and time, to acquire accurate information on target situation and movement, and to rapidly change tactics in the dynamic field.

This paper proposes an energy efficient clustering algorithm for self-organizing and self-managing WSNs, called SNOW cluster. It introduces region node selection as well as cluster head election based on the residual battery capacity of nodes to reduce the costs of managing sensor nodes and of the communication among them. SNOW cluster clusters periodically(More)
