A Case for Hierarchical Routing in Low-Power Wireless Embedded Networks

Free registration required

Executive Summary

Hierarchical routing has often been mentioned as an appealing point-to-point routing technique for wireless sensor networks (sensornets). While there is a volume of analytical and high-level simulation results demonstrating its merits, there has been little work evaluating it in actual sensornet settings. This paper bridges the gap between theory and practice. Having analyzed a number of proposed hierarchical routing protocols, the authors have developed a framework that captures the common characteristics of the protocols and identifies design points at which the protocols differ.
