DAMON: a distributed architecture for monitoring multi-hop mobile networks

Abstract

Abstract-With the advent of small form-factor devices, protocol standardization, and robust protocol implementations, multihop mobile networks are witnessing widespread deployment. The monitoring of such networks is crucial for their robust operation. To this end, this paper presents DAMON, a distributed system for monitoring multi-hop mobile networks. DAMON uses agents within the network to monitor network behavior and send collected measurements to data repositories. DAMON's generic architecture supports the monitoring of a wide range of protocol, device, and network parameters. Other key features of DAMON include seamless support for multiple repositories, auto-discovery of sinks by the agents, and resiliency of agents to repository failures. We have implemented DAMON agents that collect statistics on data traffic and the Ad hoc On-demand Distance Vector (AODV) routing protocol. We have used our implementation to monitor an ad hoc network at the 58th Internet Engineering Task Force (IETF) meeting held November 2003 in Minneapolis, MN. In this paper, we describe the architecture of DAMON and report on the performance of the IETF network using monitoring information collected by DAMON. Our network monitoring system is available online for use by other researchers.

Usage Patterns in an Urban WiFi Network

“…Numerous studies of indoor 802.11 networks have covered a variety of environments, including university departments [14], [15], [33], corporate enterprises [6], and conference and professional meetings [5], [18], [19], [22], [25], [29]. These studies have focused on network performance and reliability as well as user behavior from the perspectives of low-level network characteristics to high-level application use.…”

Monitoring of Wireless Sensor Networks

“…On the other hand, our study emphasizes the optimized node selection for the local monitoring scheme. In [47], the authors present DAMON, a distributed system for monitoring multi-hop mobile networks. DAMON uses agents within the network to monitor network behavior and send collected measurements to data repositories.…”
