Wireless sensor networks (WSNs) are used to continuously monitor certain area of interest
and send data back to the base station for processing. In many applications, WSNs serve in …

Nodes in wireless sensor networks continuously monitor their surroundings and report to the
base station if there is any anomaly. WSN in extreme environmental conditions can suffer …

Abstract Mobile Data Collectors (MDCs) can be employed to provide intermittent connectivity
in partitioned Wireless Sensor Networks (WSNs). Typically, an MDC serves multiple …

Wireless Sensor Networks (WSN) that operate unattended in harsh environments are
susceptible to large scale damage, where many nodes fail simultaneously and the network …

Abstract Wireless Sensor Network (WSN) deployed within hostile environments may suffer
from large scale damage where many sensors fail simultaneously and cause the WSN to …

Disjoint Wireless Sensor Networks (WSNs) can be reconnected by placing additional relay
nodes in the damaged areas. However, in some cases there may not be enough relays to …

In recent studies, using mobile elements (MEs) as mechanical carriers to relay data has
been shown to be an effective way of prolonging sensor network life time and relaying …

Due to harsh environmental conditions a Wireless Sensor Network (WSN) may suffer from
large scale damage where many nodes fail simultaneously and thus the network gets …

Applications that require fast response time such as emergency preparedness and hostile
environment surveillance pose challenging obstacles to wireless sensor network (WSN) …

In this paper, we present rendezvous-based data gathering protocols for wireless sensor
networks employing multiple mobile elements. For satisfying timely delivery of sensory data …
