Abstract

Scalability of algorithms used in wireless sensor networks is a critical issue due to the extremely high node numbers and relatively high node density. Few recent studies analyze the scalability of algorithms in wireless ad-hoc networks. Yet there is no significant research done on scalability of algorithms used in wireless sensor networks. In this paper, we present a brief survey of recent research on scalability of protocols for wireless ad-hoc networks followed by a scalability analysis of a typical cross-layer scheduling scheme used to improve energy efficiency in wireless sensor networks. Results show severe degradations of per-node and per-flow throughput indicating that such scheduling algorithms used in wireless sensor networks are far less scalable than the algorithms used in their ad-hoc counterparts.
