Cascading Tournament Algorithm: Low Power, High Capacity Medium Sharing for Wireless Sensor Networks

Existing Medium Access Control protocols for Wireless Sensor Networks reduce the radio activity to improve network lifetime, at the expense of a reduced network capacity. Those protocols are ill-suited for energy constrained sensor networks that must support spatially and temporally heterogeneous traffic loads. This paper proposes a novel multi-resource allocation algorithm and describes its implementation as a medium access control protocol for Wireless Sensor Networks. The algorithm, named Cascading Tournament (CT), is a localized, dynamic, joint contention/allocation algorithm. It relies on cascading iterations of tournaments to allocate a multiplicity of resources to a multiplicity of winners.
