OPTIMAL MULTICAST ROUTING IN MOBILE AD HOC NETWORK

ABSTRACTMulticast routing is an effective way to communicate among multiple hosts in a network. It outperforms the basic broadcast strategy by sharing resources along general links, while sending information to a set of predefined multiple destinations concurrently. However, it is vulnerable to component failure in ad hoc network due to the lack of redundancy, multiple paths and multicast tree structure. Tree graph optimization problems (GOP) are usually difficult and time consuming NP-hard o...

DESIGN AND IMPLEMENTATION OF A COMPUTERIZED FINANCIAL MANAGEMENT SYSTEM FOR PUBLIC INSTITUTIONS (A CASE STUDY OF UNTH, ENUGU)

ABSTRACT The proper management and utilization of financial resources has over the years been the bed rock of growth, expansion and continual existence of the world most popular industries and business organizations. In contrast, the liquidation of once popular organizations is dependent on the allocation and improper utilization of financial resources used in the running of these organization. However, due to the inadequacies and imperfection of human beings, a lot of problems such as misa...

PEER TO PEER MESSAGING

ABSTRACTPeer to peer messaging is a simple information dissemination platform that is supported by a protocol which is based on pairs of request/response PDUs (protocol data units, or packets) exchanged over OSI layer 4 (TCP session or X.25 SVC3) connections. PDUs are binary encoded for efficiency. Data exchange may be synchronous, where each peer waits for a response for each PDU being sent, and asynchronous, where multiple requests can be issued without waiting and acknowledged in a skew or...

DESIGN AND IMPLEMENTATION OF ONLINE CASH RECEIPT GENERATION SYSTEM FOR A SUPERMARKET. (A CASE STUDY OF ROBAN STORES LTD)

ABSTRACTThis project work, is a computerization of cash receipt system of an organization. It entails maintaining database files of different sources of receipt whose scope and limitation are based on. Sales and purchases Receipts/Invoices inquiry on Total Balance and generation of report. But before we venture into that, attention should be drawn to the introductory part, the literature review and later the analysis of the existing system and the design of the new system. Since, there is...

PEER TO PEER MESSAGING SYSTEM USING JXTA

ABSTRACTPeer-to-peer (P2P) computing or networking is a distributed application architecture that partitions tasks or workloads between peers. Peers are equally privileged, equipotent participants in the application. They are said to form a peer-to-peer network of nodes. Peers make a portion of their resources, such as processing power, disk storage or network bandwidth, directly available to other network participants, without the need for central coordination by servers or stable hosts. Pee...

PERFORMANCE EVALUATION DISTANCE ROUTING ALGORITHM IN MANET

ABSTRACTA mobile ad-hoc network (MANET) consists of wireless mobile hosts (nodes) that communicate with each other over wireless link, in the absence of a fixed infrastructure. Routes between two hosts in MANET may consists of hops through other hosts in the network, due to the limitation of broadcasting range of each host Movement of hosts results in a change of routes. Therefore various algorithms, to find  & maintain routes in MANET is difficult and important task for efficient ro...

PERSONAL AUTHENTICATION USING 3-D FINGER GEOMETRY

ABSTRACTIn this project, a biometric authentication system based on measurements of the user's three-dimensional (3-D) hand geometry is proposed. The system relies on a novel real-time and low-cost 3-D sensor that generates a dense range image of the scene. By exploiting 3-D information we are able to limit the constraints usually posed on the environment and the placement of the hand, and this greatly contributes to the unobtrusiveness of the system. Efficient, close to real-time algori...

DESIGN AND CONSTRUCTION OF A 12 VOLTS AUTHOMATIC BATTERY CHARGER

ABSTRACT A battery charger is an electrical device employed for charging batteries.  This batteries that are usually charged by battery changer are the storage battery charger are the storage batteries also known as “accumulator” the battery changer changes.  The alternating current form the power line into d.c suitable for charging. When the battery is fully changed, is up to it’s maximum, 12 volt, the charger with automatically stop changing with the help of the contact re...

DESIGN AND IMPLEMENTATION OF A COMPUTERIZED PHARMACY MANAGEMENT SYSTEM ( CASE STUDY OF JUHEL PHARMACEUTICALS LTD, ENUGU)

ABSTRACTThis project is written to help Pharmaceuticals Companies especially Jahel Pharmaceuticals ltd Enugu in the areas they encounter problems in keeping their record and the solution given to tackle those problem.The research was carried out of many difficulties such as time factors, money and inability to get much information that could have been of help. But still with all those the researcher came up with something readable and valuable to any body that goes through it. TABLE OF C...

DESIGN AND CONSTRUCTION OF A CASSAVA GRATING MACHINE

ABSTRACTThere is need for the hygienic processing of cassava prevalent conditions in the commercial grating areas of this staple food show a susceptibility to food contamination.  A home scale cassava grater was improved on in a design and fabrication.  Machine efficiency, safety factors, and portability were considered in this research.  The grating hopper and clinte were modified using stainless steel sheet, the machine runs on single phase 6.5hp (horse power) diesel engine a...

NETWORK BASED PERFORMANCE ANALYSIS AN OVERVIEW

ABSTRACTA network based performance analysis tool is an instrument that measures the network parameters of electrical networks. Today, network based performance analysis tool commonly measure s–parameters because reflection and transmission of electrical networks are easy to measure at high frequencies, but there are other network parameter sets such as y-parameters, z-parameters, and h-parameters. Network based performance analysis tool are often used to characterize two-port networks such...

NETWORK LOAD BALANCING AND REDISTINATION OF THE TRAFFIC OVER THE NETWORK USING GRID COMPUTING SYSTEM

ABSTRACTThe load balancing is the most important issues to reduce congestion in Autonomous computer networks. The inter-domain traffic control methods have been addressed by researchers. In this paper, we are proposed HTS; a BGP-based hierarchical network traffic reconfiguration method to redistribute traffic on overloaded link for IP-based network. Proposed algorithm fulfills at two steps. Firstly overload detection function through an explorer algorithm to construct overloaded link table du...
