—WPAN technologies such as IEEE 802.15.4 have been introduced to allow for energy-efficient communication of control and sensor data. In certain application areas, it is benefici...
Motivated by optimization problems in sensor coverage, we formulate and study the Minimum-Area Spanning Tree (mast) problem: Given a set P of n points in the plane, find a spannin...
The current specification for IEEE 802.15.4 beacon-enabled networks does not define how active and sleep schedules should be configured in order to achieve the optimal network perf...
—This paper analyzes the carrier-to-interference ratio of the so-called shotgun cellular system (SCS). In the SCS, basestations are placed randomly according to a two-dimensional...
