With the rapid growth of wireless sensor technology, the authors foresee a need for MAC protocols to allow efficient simultaneous peer-to-peer communications in large and dense wireless sensor networks. To meet such a need, they propose a novel MAC protocol that exploits network graphs property to assign frequencies such that the number of intermediate hops to reach destinations is minimized. Via a simulation model parameterized to CrossBow MICA2, they evaluate the performance of their MAC protocol with Cayley and Manhattan Street networks.
