, consisting of a Wired Infrastructure, a Wireless Sensor Network (WSN) and a Power Line Communications (PLC). The system is based on three hardware topologies responsible for the signal acquisition, processing, and transmission: Remote Data Acquisition Units (RDAU's), Intelligent Sensors Modules (ISM

. The communication protocols are Ethernet-based that used contention access protocols which result in high unsuccessful transmission and delay. The use of embedded wireless sensor and actuator networks for monitoring and control of the electric grid requires secure, reliable and timely exchange of information among

Abstract—Wireless machine-to-machine (M2M) networks are becoming a relevant topic in the field of home automation and advanced security systems. A wireless network for indoor intrusion detection is based on several sensors that are deployed over the monitored area for detecting possible risky

Recently, Cognitive radio and Smart Grid are two areas which have received considerable research impetus. Cognitive radios are fully pro-grammable wireless devices that can sense their environment, and dy-namically adapt their transmission waveform, channel access method, spectrum use

Per has in a seemingly easy way spotted erroneous assumptions, has valued my research contributions, and has connected my own work with another broader world of research. I want to thank all colleagues in the Networked

lifetime, while less emphasis was placed on both transmission delay reduction and the adaptive sleep of sensor nodes considering the application constraints. In this paper, we propose a smart power management and delay reduction approach for target tracking based on a grid network structure, where sensor

these protocols build and maintain substantial network state to cope with the dynamics of low-power wireless links. Recent protocols depart from this design by leveraging synchronous transmissions (ST), whereby multiple nodes simultaneously transmit towards the same receiver, as opposed to pairwise link-based
