In this paper we present a demonstration of a novel management architecture for heterogeneous wireless sensor networks (WSNs) called MARWIS. The architecture supports common management tasks such as monitoring, (re)configuration, and updating program code in a WSN. It considers specific characteristics of sensor nodes. To handle large heterogeneous WSNs MARWIS divides it into smaller sensor sub...

Wireless Sensor Networks are gaining more and more importance in present era. Recent Advances in WSN have extended the applicability of these to wide range of real time applications. One of these recent advances in WSN is invention of Heterogeneous Wireless Sensor networks (HWSN). Compared to Homogenous, Heterogeneous have large curve of applicability. However, whether it is Homogenous WSN or H...

In modern scenario we need to have mechanisms which can provide better interaction with physical world by an efficient and more effective communication and computation approach for multiple heterogeneous sensor networks. Previous work provides efficient communication approach between sensor nodes and a query centric approach for multiple collaborative heterogeneous sensor networks. Even there i...

A secure scheme for heterogeneous wireless sensor networks is presented. The wireless sensor networks have some sensor nodes and heterogeneous sensor nodes that have greater power and transmission capability than other nodes have. All kinds of sensor nodes are evenly distributed respectively in entire sensing area that is divided into a number of same cells and logical groups evenly. The pairwi...

coverage improvement is one of the main problems in wireless sensor networks. given a finite number of sensors, improvement of the sensor deployment will provide sufficient sensor coverage and save cost of sensors for locating in grid points. for achieving good coverage, the sensors should be placed in adequate places. this paper uses the genetic and learning automata as intelligent methods for...
