Wireless local area networks (WLANs) have risen in popularity for in-car networking systems that are designed to make driving safer. Wireless mesh networks (WMNs) are widely deployed to expand the coverage of high-speed WLANs and to support last-mile connectivity for mobile users anytime and anywhere at low cost. Many recent measurement studies have shown that the traffic arrival process in wireless...
Data aggregation is generally considered an important method used to reduce traffic and increase lifetime of wireless sensor networks in both two- and three-dimensional space. It is challenging to develop efficient data aggregation solution for the wireless sensor networks since quality-of-service, such as end-to-end delay, is considered as a severe criterion required in many scenarios. In this paper...
Machine-to-Machine (M2M) technologies allow network-to-device communications. M2M covers a wide scope of technologies including sensing and wireless networking protocols. Hazard monitoring applications based M2M such as monitoring using wireless sensor networks (WSNs) are challenged by real-time and interference-aware requirements. The designed communication mechanisms need to guarantee efficient...
In this work we design a virtual backbone to provide energy-efficient communication in Wireless Sensor Networks (WSNs). WSNs need virtual backbones to support in-network data transmission. In scenarios where there is no spatial redundancy (such as a sensor network in a petroleum installation), Connected Dominating Set (CDS)-based algorithms can be useful for hierarchical network management. We construct...
