Unreliable Sensor Grids: Coverage, Connectivity and Diameter
Abstract— We consider an unreliable wireless sensor gridnetwork with n nodes placed in a square of unit area. We are interested in the coverage of the region and the connectivity...

Taming the underlying challenges of reliable multihop routing in sensor networks
The dynamic and lossy nature of wireless communication poses major challenges to reliable, self-organizing multihop networks. These non-ideal characteristics are more problematic ...

Asymptotically optimal time synchronization in dense sensor networks
We consider the problem of synchronization of all clocks in a sensor network, in the regime of asymptotically high node densities. We formulate this problem as one in which all cl...
