In the publish/subscribe (pub/sub) communication scheme in wireless sensor networks (WSNs), there exist inherent tradeoffs among conflicting objectives in event publication. To address this issue, this paper investigates pub-/sub middleware for WSNs, called TinyDDS. With its self-configuring event routing protocol, TinyDDS adaptively performs event publication according to dynamic network conditions...
The IEEE 802.15.4 and ZigBee protocol stack offers great potentials for ubiquitous and pervasive computing, namely for wireless sensor networks. However, there are still some open and ambiguous issues that turn its practical use a challenging task. One of those issues is the study of low power consumption of sensor device, which is the biggest issue in sensor network, still has many unresolved issues...
In wireless sensor networks (WSNs), a challenging problem is how to advance network QoS. Energy-efficiency, network communication traffic and failure-tolerance, these important factors of QoS are closely related with the applied performance of WSNs. Hence a QoS-aware routing protocol called directed alternative spanning tree (DAST) is proposed to balance the above three factors of QoS. A directed...
