We examine distributed time-synchronization in mobile ad-hoc and sensor networks. The problem is to estimate the skews and offsets of clocks of all the nodes with respect to an arb...
An ad hoc or sensor network that is employed for security sensitive applications is expected to tolerate a certain quantity of maliciously behaving nodes. Algorithms must be desig...
Using directional antennas in wireless ad hoc networks can significantly improve network performance. However, the deafness problem greatly limits the network performance. This pa...
Abstract—Employing multiple base stations is an attractive approach to enhance the lifetime of wireless sensor networks. In this paper, we address the fundamental question concer...
When tracking a target using phase-only signal returns, range ambiguities are a major issue. In this work, a look-up table between phase measurement space and target location spac...
