Internal synchronization of drift-constraint clocks in ad-hoc sensor networks
Clock synchronization is a crucial basic service in typical sensor networks, since the observations of distributed sensors more often than not need to be ordered ("a happened...

Time and energy complexity of distributed computation in wireless sensor networks
— We consider a scenario where a wireless sensor network is formed by randomly deploying n sensors to measure some spatial function over a field, with the objective of computing...

On Scheduling and Real-Time Capacity of Hexagonal Wireless Sensor Networks
Since wireless ad-hoc networks use shared communication medium, accesses to the medium must be coordinated to avoid packet collisions. Transmission scheduling algorithms allocate ...

Chaining Clock Synchronization: An Energy-Efficient Clock Synchronization Scheme for Wireless Sensor Networks
— Since WSNs have restricted energy sources, the energy efficiency of a synchronization scheme is as important as the accuracy of a clock. To accomplish both the energy efficienc...
