OMNET++ NETWORK CODING
Network security plays a vital role in today’s world because more number of users using network and internet access. Various number of confidential information are stored, transferred and accessed by internet which eradicate security issues in network is important. We offer projects in network security OMNET++ for students with various security algorithm development and protocol implementation. We ensure OMNET++ NETWORK CODING to develop security based projects for undergraduate B.E, B.TECH students with various frameworks. We simulate and handle various security issues in wireless body area network, wireless sensor network, vehicular Adhoc network and software defined network for college projects.
OMNET++ NETWORK CODING
Security issues under OMNET++:
We handle following security issues in more than 80 projects in OMNET++ simulation.
Collisions form when two or more node trying to send data on same frequency. By this process, data portion got modified which result in mismatch at destination. Then the packet is invalid or discarded.
It happened in physical nodes which contain various cryptographic keys. Node can be modified or replaced to create compromised nodes.
In this attack, attacker change or replay routing information to ensure network traffic network disruption include extend routes or shorten routes, attract network traffic from select nodes, gather fake error message, end to end latency and routing loops.
In this attack, attacker gets illegal multiple identities on one node. Sybil attack prevents various validation techniques.
It created by interferes of radio frequencies. In network such as wireless sensor network and wireless body area network attacker send various radio waves at same frequency which affect data transmission among network.
Hello flood Attack:
In wireless sensor network attacker send broadcast hello packets with high transmission power to sender and receiver. By hello packets congestion occur in network.
Security mechanism used in simulation:
We simulate various mechanisms in OMNET++ to protect data over transmission.
We use encryption in network security to enhance authentication, integrity, confidentiality and protection. We implement digital signature checksum to provide integrity protection, reputation and authentication.
SPINS (security protocol for sensor network):
We implement SPIN algorithm optimized for resource constraint and low communication overhead. We provide authentication mechanism such as confidentiality freshness and authentication.
Mechanisms for attacks on routing protocol:
To prevent attack such as wormhole, Sybil attack, and sinkhole we implement high technique called TRANS (trust routing for location aware sensor network) protocol for data centric network.
Shared key mechanism:
We use public and private key for data communication and to access network. These keys are paired and share secret key as password. We provide various mechanism and techniques to solve security issues under various applications.
