Design and implementation of an unstructured overlay middleware to support MANET applications

Recently, mobile ad hoc networks (MANET) have gained an enormous popularity, which has led to an increasing need for the development of MANET applications. Developing MANET applications, however, is not an easy task. Developers have to deal with difficulties inherent from the wireless network environments. In this thesis, the design of a middleware that abstracts the functionalities of an unstructured overlay network is proposed. The main non-functional requirements that our design tries to achieve are portability, efficiency, and usability. Portability is achieved by following the J2ME platform specifications. The middleware has been implemented and tested on a real time ad hoc network using different platform devices. The performance measurements of the middleware show that it achieves its efficiency requirements. Furthermore, the middleware's usability is validated by showing how different applications can be designed and deployed easily on top of it. It provides a simple MBR-based file-search and path establishment mechanisms which we have proved to be the basis for implementing a wide range of applications, such as file sharing, ALM and gaming applications.

A DHT-Supported Piece Driven Overlay for P2P Live Gushing

Peer-to-peer live streaming technologies allow a constricted source of data transmission to transmit a video that encourages a significant amount of customers. The primary objective of live gushing is to convey stream information to all customers previously their playback due date. Outline effectiveness is basically described by the spilling rate that can be managed, and by the postpone it takes for information to achieve customers from the source. Furthermore, a plan with high connection usage can accomplish high stream rates, supporting amazing video. As of recently, just tree-based plans have been appeared to accomplish near ideal rates, all items regarded, circumstances, leaving the investigation open as to the viable efficacy of completely unstructured methodologies based on job.We answer that inquiry by demonstrating that a painstakingly composed work based framework can accomplish near ideal stream rates In particular, in the context of a work-based count called DP / LU, we are executing and surveying a structure. Instead of tree-based diagrams, DP / LU utilizes an unstructured overlay that is less demanding to produce and extremely impenetrable to mix. Moreover, we recognize a few outline advancements which help enhance the rate and defer execution of work based frameworks. Our experiment evaluation shows that in a static scenario, our sketch achieves 95% of the most severe achievable flow speed and 90% under elevated agitate. This displays work-based outlines are an amazing choice for live spilling distributed versatile and powerful top notch. Live video spilling administrations are spreading rapidly finished the Internet. To tell the truth, many frameworks use basic gushing conventions that underuse uplinks from customers, squandering accessible transmission capacity. This problem will turn out to be more authentic as customers will demand top notch entertainment in the near future, increasing the necessary stream bitrates. This prompts the associated investigation: are tree-based plans going to exchange working schedules oriented on top-notch live video gushing? We trust that the appropriate response is no. To help this, we play out an examination which demonstrates that a precisely planned work based framework can accomplish close ideal rates and low dissemination delays.
