Location based Multicast Addressing (LMA) is a technique used to distribute information to the multiple nodes surrounded by a particular geographical area. It mainly applied for context aware applications in mobile ad hoc networks (MANETs). In this Location matching process done between middleware of publish/subscribing environment. In this paper introduce, one new feature is implemented for creating context awareness among mobile network to analyze how many users are currently located in the mobile network, and how many of them discarded from the network because of low energy level. The Bandwidth of each node is calculated to know the energy level status. Some of nodes in mobile network utilize more bandwidth. Allocate bandwidth equally to all nodes to avoid packet dropping and also identify the nodes information using keys provided by AES algorithm it is also helpful to improve security in mobile network.General Terms: Publish/Subscribe, Middleware

“…Research in subscription and notification routing systems has mostly focussed on static topologies [9] where mobility concerns are delegated to the applications (consumers, producers of events) e.g. in JEDI, which uses explicit moveIn and moveOut operations to relocate clients.…”

“…Hence, mobility management is delegated to the applications/clients and not controlled by the brokers. Podnar and Rovlek [9] propose an approach for managing mobility in which the brokers store persistent notifications until their validity period expires. Huang and Garcia-Molina [10] have also suggested algorithms for managing mobility in single and multiple broker based systems but such algorithms have not been incorporated and analysed in context-aware systems.…”

Software systems that provide context-awareness related functions in pervasive computing environments are gaining momentum due to emerging applications, architectures and business models. In most context-aware systems, a central broker performs the functions of context acquisition, processing, reasoning and provisioning to facilitate context-consuming applications, but demonstrations of such prototypical systems are limited to small, focussed domains. In order to develop modern context-aware systems that are capable of accommodating emerging pervasive/ubiquitous computing scenarios, are easily manageable, administratively and geographically scalable, it is desirable to have multiple brokers in the system divided into administrative, network, geographic, contextual or load based domains. Context providers and consumers may be configured to interact only with their nearest, relevant or most convenient broker. This setup demands inter-broker federation so that providers and consumers attached to different brokers can interact seamlessly, but such a federation has not been proposed for context-aware systems. This article analyses the limiting factors in existing context-aware systems, postulates the design and functional requirements that modern context-aware systems need to accommodate, and presents a federated broker based architecture for provisioning of contextual information over large geographical and network spans

“…When the mobile client changes its home broker, a handoff protocol is utilized for event delivery between two brokers. Similarly, several other mobility management protocols [5], [8] are studied. Unfortunately, all of these protocols are based on infrastructured wireless networks, where the backbone network is still wired and only end users are mobile.…”

DRIP: A Dynamic VoRonoi RegIons-Based Publish/Subscribe Protocol in Mobile Networks

Abstract-The publish/subscribe (pub/sub for short) paradigm is used to deliver events from a source to interested clients in an asynchronous way. Recently, extending a pub/sub system in wireless networks has become a promising topic. However, most existing works focus on pub/sub systems in infrastructured wireless networks. To adapt pub/sub systems to mobile ad hoc networks, we propose DRIP, a dynamic Voronoi region-based pub/sub protocol. In our design, the network is dynamically divided into several Voronoi regions after choosing proper nodes as broker nodes. Each broker node is used to collect subscriptions and detected events, as well as efficiently notify subscribers with matched events in its Voronoi region. Other nodes join their nearest broker nodes to submit subscriptions, publish events, and wait for notifications of their requested events. Broker nodes cooperate with each other for sharing subscriptions and useful events. Our proposal includes two major components: a Voronoi regions construction protocol, and a delivery mechanism that implements the pub/sub paradigm. The effectiveness of DRIP is demonstrated through comprehensive simulation studies.
