As the wireless sensor network (WSN) technology evolves towards higher transmission rates, it makes sense to start considering sensing and transmission of real-time information, such as audio and video. These applications require quality of service (QoS) guarantees, not offered by current networks. The multi-hop nature of WSN makes QoS a challenging task. In addition, researchers have recently realized...
This paper presents a customizable framework for employing Cognitive Radio in Intermittently Connected Wireless Networks, which aims to maximize transmission opportunities that arise when fully connected network partitions are formed. Various layer 3 routing and information dissemination protocols would benefit from increased opportunity utility. We propose to use Cognitive Radio to permit multiple...
We address two critical issues in wireless sensor networks: (1) an extension of common Quality of Service (QoS) parameters to study the effects of ultra-low duty cycling applications, and (2) propose a new WSN passive clustering routing protocol using sleep cycles based on available renewable energy resources : Fusion Ambient Renewable MACS (FARMS). The results from lifetime based QoS in a time synchronized...
