Performance of publish/subscribe middleware in mobile wireless networks

Abstract

Publish/subscribe middlewares are becoming popular for distributed applications because of their flexible and scalable nature. Anonymous and loosely-coupled communication between publisher and subscriber, along with the inherently asynchronous nature of these systems, help them adapt quickly to changing environments, making them a good choice for mobile cellular networks. This paper studies publish/subscribe middleware performance in such networks in detail. As a first step, the paper characterizes a popular implementation of publish/subscribe system for the mobile domain, studying and analyzing the effect of different mobility parameters, which to the best of our knowledge is the first experimental research on the performance behavior of publish/subscribe systems in a mobile wireless domain. As a second step the paper presents the design, implementation and evaluation of middleware level handoffs, a well known solution to extend publish/subscribe systems to a mobile domain, and identifies the performance concerns of such extensions. The results show that such handoff protocols involving two brokers are impractical from a performance perspective under highly dynamic and unreliable mobile wireless settings. The paper identifies the basic reason for the limitations of middleware level handoffs.

Subscriber mobility management for a P2P publish/subscribe overlay in mobile tactical networks

“…Farooq et al [10,11] studied a durable subscriptionbased approach, which is quite popular and adopted by publish/subscribe systems that apply the Java Messaging Service [18] standards. It requires each broker to store all the published messages.…”

Information Management in Mobile Environments Using a Location-Aware Intelligent Agent System

“…Congruent with our thinking, many researchers have acknowledged the potentials of applying a Pub/Sub system to wireless platforms. A few highlighting studies in this area include Caporuscio et al (2003), Cilia, Fiege, Haul, Zeidler, and Buchmann (2003), Chen et al (2003), Farooq et al (2004), Heimbigner (2000), Huang andGarcia-Molina (2004), andMuhl (2004). Much past research in this domain has focused either on development of Pub/Sub infrastructure or performance-oriented aspects of it.…”

“…This research focuses on enhancing the operational effectiveness of Pub/Subbased infrastructure in a wireless environment. Farooq et al (2004) have strictly studied the performance-related aspects of Pub/Sub middleware in mobile wireless networks. They studied publisher throughput, subscriber throughput, message loss, and handoffs, as well as workload parameters such as bandwidth, message and connection load, message size, and so on.…”

“…Publish/Subscribe (referred to as Pub/Sub from hereon) middleware has acquired attention and approval of researchers and is becoming popular tool for data dissemination in mobile environments (Anceaume, Datta, Gradinariu, & Simon, 2002;Baldoni, Beraldi, Querzoni, & Virgillito, 2004;Chen, Chen, & Rao, 2003;Farooq, Parsons, & Majumdar, 2004;Fenkam, Kirda, Dustdar, Gall, & Reif, 2002;Jose, 2004). It can offer distinguished assistance in extending the advantages of service-based architectures to the development of location-based services.…”

A pro-active mobility management scheme for publish/subscribe middleware systems

“…Farooq et al [34] [35] report their experience in evaluating the performance of SonicMQ Their approach is similar to the one introduced by [32] [33]. The only difference is that the mobility support service (Handoff Manager) is integrated with the broker into a single entity instead of being run as a separate entity.…”
