“…The sender and receiver in AES use the same key to encrypt and decrypt data that called symmetric encryption so the key must be kept secured. [16] The Advanced Encryption Standard (AES) is receiving deployed in more and more solutions. The future work attempts to adapt the 256 bit block and key for Mobile Ad-Hoc Network Environment, encoding the text data to reduce input bits keeping the amount of computation less conforming to limitations of power of the devices consumed.…”

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

“…Corresponding middleware solutions which support updates handle them in an ad-hoc manner [Meier and Cahill 2010;Holzer et al ]. Wildcards: The simplest approach to programmatically express adaptations on content-based subscriptions is to use wildcard matching for respective event attributes, leading to universal subscriptions reminiscent of topic-based subscriptions.…”

Content-based publish/subscribe (CPS) is an appealing abstraction for building scalable distributed systems, e.g., message boards, intrusion detectors, or algorithmic stock trading platforms. More recently, extensions of the abstraction have been proposed for location-based services like vehicular networks, mobile social networking, etc.Although current CPS middleware systems are dynamic in the way they support the joining and leaving of publishers and subscribers, they fall short in supporting subscription adaptations. These are becoming increasingly important across many CPS applications. In algorithmic high frequency trading, for instance, stock price thresholds that are of interest to a trader change rapidly, and gains directly hinge on the reaction time to relevant fluctuations rather than fixed values. In location-aware applications, a subscription is a function of the subscriber location (e.g. GPS coordinates) which inherently changes during motion.The common solution to adapt a subscription consists in a re-subscription, where a new subscription is issued and the superseded one canceled. This incurs substantial overhead in CPS middleware systems, and leads to missed or duplicate events during the transition. In this paper, we explore the concept of parametric subscriptions for capturing subscription adaptations. We discuss desirable and feasible guarantees for corresponding support, and propose novel algorithms for updating routing mechanisms effectively and efficiently in classic decentralized CPS broker overlay networks. Compared to re-subscriptions, our algorithms significantly improve the reaction time to subscription updates without hampering throughput or latency under high update rates. We investigate pathological cases of high frequency subscription oscillations, which could significantly decrease the throughput of CPS systems thereby affecting other subscribers. We propose and evaluate approximations techniques to detect such oscillations and mitigate the event filtering burden they place on the CPS system.We convey analyze the benefits of our support through implementations of our algorithms in two CPS systems, and by evaluating our algorithms on two different application scenarios.
