Project on Network Simulation using OMNeT++ 3.2

1. Efficient Routing via Clustering using OMNeT (Type-A)

Basepaper: Efficient Node Search in P2P Using Distributed Spanning Tree ((IJCSIS) International Journal of Computer Science and Information Security,
Vol. 8, No. 3, June 2010)

Peer to Peer (P2P) networks are the important part of the next cohort of Internet, so how to search the node in the P2P networks efficiently is the key problem of the perception of the P2P network. However, the node search process in unstructured P2P is not efficient because the same search message may go through a node multiple times. To ease the complex search and improve the search efficiency, we propose a mechanism using the interconnection structure called Distributed Spanning Tree (DST) which facilitates the P2P Network into a layered structure to improve the node search technique. The performance evaluations of simulation demonstrate that the proposed mechanism can improve the node search efficiency of P2P systems.

2. Global Replica Management in Distributed Environment using OMNeT
(Type-C)

Basepaper: QoS enhancements for global replication management in peer to peer networks (Future Generation Computer Systems (2011), Elsevier, Volume 28, Issue 3, March 2012)

Replica Management is a key issue to reduce the bandwidth consumption, to improve data availability and to maintain data consistency in large distributed systems. Global Replica Management (GRM) means to maintain the data consistency across the entire network. It is preferable particularly for multi-group distributed systems. On the other hand, GRM is not favorable for many applications because a very large number of message passes is needed for replica management processes. In this paper, in order to reduce the number of message passes needed to achieve the efficient GRM strategy, an interconnection structure called the Distributed Spanning Tree (DST) has been employed. The application of DST converts the peer network into logical layered structures and thereby provides a hierarchical mechanism for replication management. It is proved that this hierarchical approach improves the data availability and consistency across the entire network. In addition to these, it is also proved that the proposed approach reduces the data latency and the required number of message passes for any specific application in the network.

3. Minimum Distance Packet Forwarding using OMNeT (Type-B)

Base Paper: MDPF: Minimum Distance Packet Forwarding for Search Applications in Mobile Ad Hoc Networks (IEEE TRANSACTIONS ON MOBILE COMPUTING, VOL. 8, NO. 10, OCTOBER 2009)

This work introduces a message forwarding algorithm for search applications within mobile ad hoc networks (connected) that is based on the concept of selecting the nearest node from a set of designated nodes. The algorithm, which is called Minimum Distance Packet Forwarding (MDPF), uses routing information to select the node with the minimum distance. The goal of the proposed algorithm is to minimize the average number of hops taken to reach the node that holds the desired data. Numerical analysis and experimental evaluations using the network simulation software OMNeT++ to derive the lower and upper bounds of the confidence interval for the mean hop count between the source node of the data request, on one hand, and the node that holds the desired data and the last node in the set of search nodes, on the other hand.


4. Cooperative Cache Technique using OMNeT (Type-B)

Basepaper: Cluster-Based Cross-Layer Design for Cooperative Caching in Mobile Ad Hoc Networks (IEEE SYSTEMS JOURNAL, VOL. 3, NO. 4, DECEMBER 2009)

Several protocols have been proposed to improve data accessibility and reduce query delay in MANETs. Some of these proposals have adopted the cooperative caching scheme, allowing multiple mobile hosts (connected) within a neighborhood to cache and share data items in their local caches. Cross-layer optimization has not been fully exploited to further improve the performance of cooperative caching in these proposals. In this paper we propose a clusterbased cooperative caching scheme. A cross-layer design approach is employed to further improve the performance of cooperative caching and prefetching schemes. The experimental results in the OMNeT++ simulation environment demonstrate that the proposed approach improves caching performance in terms of data accessibility, query delay and query distance compared to the caching scheme that does not adopt the cooperative caching strategy.

5. Effective Query Retrieval in Mobile Environment using OMNeT (Type-A)

Basepaper: EFFECTIVE QUERY RETRIEVAL SYSTEM IN MOBILE BUSINESS ENVIRONMENT ((IJCSIS) International Journal of Computer Science and Information Security, Vol. 7, No. 3, March 2010)

Query Management System (WBQMS) is a methodology to design and to implement Mobile Business, in which a server is the gateway to connect databases with clients which sends requests and receives responses in a distributive manner. The gateway, which communicates with mobile phone via GSM Modem, receives the coded queries from users and sends packed results back. The software which communicates with the gateway system via SHORT MESSAGE, packs users’ requests, IDs and codes, and sends the package to the gateway; then interprets the packed data for the users to read on a page of GUI. Whenever and wherever they are, the customer can query the information by sending messages through the client device which may be mobile phone or PC. The mobile clients can get the appropriate services through the mobile business architecture in distributed environment

6. Endpoint Admission Control using OMNeT (Type-B)

Basepaper: Congestion Notification and Probing Mechanisms for Endpoint Admission Control (IEEE/ACM TRANSACTIONS ON NETWORKING, VOL. 14, NO. 3, JUNE 2006)

There has been much interest in admission control schemes that place the burden of admission control decisions on the end users. In these schemes, referred to as Endpoint Admission Control, the decision to join the network is taken by the user, based on the probing of the network using probe packets. Depending on the level of congestion, routers mark the probe packets and thus inform the user of the state of the network. We analyze the probing duration necessary to guarantee the required QoS and achieve high page link utilization

7. Effective Packet Marking to find the real attacks in Internet (Type-B) (under development)

Basepaper: Flexible Deterministic Packet Marking: An IP Traceback System to Find the Real Source of Attacks (IEEE TRANSACTIONS ON PARALLEL AND DISTRIBUTED SYSTEMS, VOL. 20, NO. 5, MAY 2009)

Internet Protocol (IP) traceback is the enabling technology to control Internet crime. In this paper, we present a novel and practical IP traceback system called Flexible Deterministic Packet Marking (FDPM) which provides a defense system with the ability to find out the real sources of attacking packets that traverse through the network. While a number of other traceback schemes exist, FDPM provides innovative features to trace the source of IP packets and can obtain better tracing capability than others
