Duty cycling is often used to reduce the energy consumption caused by idle listening in Wireless Sensor Networks (WSNs). Most studies on WSN protocols define a common duty cycle va...
Abstract--We present a new scheme to reduce the end-toend routing delay in the mission-critical applications of the wireless sensor networks (WSNs) under the duty cycle model. Whil...
Most of Voice over IP(VoIP) systems are deployed using SIP protocol and based in a client-server architecture. A lot of people and companies could be benefited if the system did n...

— What is the fastest rate at which we can collect a stream of aggregated data from a set of wireless sensors organized as a tree? We explore a hierarchy of techniques using real...
As ICT services are becoming more ubiquitous and mobile and access technologies grow to be more heterogeneous and complex, we are witnessing the increasing importance of two relat...
