摘要:In this paper, we investigate the sensor localization problem and present Stochastic Radio Interferometric Positioning System with Unsynchronized Modulated Signals (SRIPS_UMS). Previous radio interferometric positioning methods have limitations include (1) strict hardware require...

摘要:We present a theoretical performance analysis of network lifetime for sensor networks that route packets through multiple paths between a source and destination pair. Our analysis is based on the length of the paths established and we show how this value can be used to estimate t...

摘要:Included in the performance goal of most wireless sensor network applications are both spatial coverage and extended network lifetime. Pure energy efficient routing protocols,such as Shortest Path, cannot satisfy this need, since sensor nodes along the data path may have their en...

摘要:Wireless sensor networks are often used to sample the state of physical phenomena in space. Sensor nodes, which usually have limited energy, collect data locally and forward them to a sink node. Thus there are two operating domains pertinent to the performance of such networ...
