Obstacles are but pleasing for many aspects of large realworld sensor networks. Among other things, the presence of obstacles distort the sensor node localization process and migh...
Abstract-- We consider the problem of estimating the geographic locations of nodes in a wireless sensor network where most sensors are without an effective self-positioning functio...
Abstract— Broadcast operation, which disseminates information network-wide, is very important in multi-hop wireless networks. Due to the broadcast nature of wireless media, not a...
