We argue that for a highly dynamic network such as ours, GWMAC is more desirable over more widespread protocols such as S-MAC and LMAC.  ...  In light of these challenges, we present a low power sensor node design and an energy-efficient medium access control protocol called GWMAC developed for a network deployed in a glacier in Norway.  ...  Also a special thanks to Gro and Inge Melkevol for their logistical help in Norway. This project was funded by the EPSRC UK.  ...

We consider a distributed optimization problem whereby a network of N nodes, S ℓ , ℓ ∈ {1, . . . , N }, wish to minimize a common strongly convex function under the constraint that node S ℓ controls variable  ...  In particular, we study the minimum amount of communication energy required for nodes to obtain an ϵ-minimizer of f (x) in the mean square sense.  ...  Zou, "Gwmac-a tdma based mac protocol for a glacial sensor network," in Proceedings of 4th ACM PE-WASUN, 2007.
