The emergence of coverage holes in wireless sensor networks (WSNs) means that some
special events have broken out and the function of WSNs will be seriously influenced …

In this work, a new hybrid clustering routing protocol is proposed to prolong network life time
through detecting holes and edges nodes. The detection process attempts to generate a …

In a wireless sensor network (WSN), sensors collect data that need to be delivered to a base
station. This requires that the WSN should be a connected network. However, due to …

Physical damage and/or node power exhaustion may lead to coverage holes in WSNs.
Coverage holes can be directly detected by certain proximate nodes known as boundary …

Wireless sensor networks (WSNs) comprise a large number of sensor nodes, which are
spread out within a region to be monitored and communicate using wireless links. In some …

In online contextual advertising, ad messages are displayed related to the content of the
target Web page. It leads to the problem in information retrieval community: how to select the …

Abstract Wireless Sensor Networks (WSN) have given a new approach for applications such
as surveillance, tracking, and monitoring. In such monitoring systems, the sensor nodes at …

Wireless Sensor Networks (WSN) have given a new approach for applications such as
surveillance, tracking and monitoring. Such applications requires perimeter nodes to remain …

Wireless Sensor Networks (WSN) display nonuniform energy usage distribution. This is
mainly induced by the sink centric traffic or by non-uniform distribution of sensing activities …

We propose two novel algorithms for distributed and location-free boundary recognition in
wireless sensor networks. Both approaches enable a node to decide autonomously whether …
