Energy consumption and timely requirements are two key factors affecting the performance of mission-critical cyber-physical systems. Little work deals with scheduling a set of time-sensitive services in a finite time interval. We consider a server serving N users in time interval [0, T]. Each user demands its service to be completed in a strict deadline.(More)
—Topology control is one of the most important energy-saving techniques used in wireless sensor networks. It has evolved into two dominant research directions: power control and sleep scheduling. Although many topology control algorithms and protocols are claimed to be highly energy-efficient, this is not necessarily the case in real systems due to various(More)
The selection of routes is an important issue in wireless networks when network coding is used. Existing researches formulated network-coding-aware routing as a linear optimization program. However, deploying such method in real wireless networks is impractical. To solve this issue, in this paper, a practical network-coding-aware routing protocol is(More)
Localization is the foundation of several techniques and applications and plays an important role in Wireless sensor network (WSN). A variety of localization algorithms are based on Received Signal Strength Indicator (RSSI). Although the RSSI-based localization technology needs no additional hardware, the accuracy of this method could not meet the(More)
