Practical DHT-Based Location Service for Wireless Mesh Networks

摘要

Mobility management in Wireless Mesh Networks (WMN) is a hot topic still lacking a final, widely accepted, and deployed solution. The major drawbacks of existing proposals is the fact that they rely on some sort of flooding-based technique and very often they need support from end-users' devices. Flooding in wireless environments leads to increased latency and broadcast storm problems, thus providing low performances. In this paper, we argue that a DHT-based approach can overcome such limitations and provide an effective solution to the mobility management problem. A preliminary evaluation of our DHT-based scheme on a real WMN test-bed shows encouraging results when compared to previous solutions.
