Run time assurance of application-level requirements in wireless sensor networks
Continuous and reliable operation of WSNs is notoriously difficult to guarantee due to hardware degradation and environmental changes. In this paper, we propose and demonstrate a ...

Cooperative contention-based forwarding for wireless sensor networks
Cooperative forwarding has been considered as an effective strategy for improving the geographic routing performance in wireless sensor networks (WSNs). However, we observe that ...

Mitigating Performance Degradation in Congested Sensor Networks
Data generated in wireless sensor networks may not all be alike: some data may be more important than others and hence may have different delivery requirements. In this paper, we a...

ACR: Active Collision Recovery in Dense Wireless Sensor Networks
Abstract—Packet collision causes packet loss and wastes resources in wireless networks. It becomes even worse in dense WSNs, due to burst-traffic and congestion around sinks. In...

Time-Critical Underwater Sensor Diffusion with No Proactive Exchanges and Negligible Reactive Floods
— In this paper we study multi-hop ad hoc routing in a scalable Underwater Sensor Network (UWSN), which is a novel network paradigm for ad hoc investigation of the world below th...
