Novel Sensor MAC Protocol Applied to Cayley and Manhattan Street Networks with CrossBow MICA2

Abstract

With the rapid growth of wireless sensor technology, we 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, we 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, we evaluate the performance of our MAC protocol with Cayley and Manhattan Street networks
