Label Switch Path

Kualitas koneksi khususnya pada backbone menjadi tantangan Internet Service Provider (ISP). MPLS berkerja di layer 2,5 OSI yang mampu mempercepat pengiriman paket pada jaringan backbone. MPLS melekatkan label pada paket yang dikirimkan. Salah satu layanan dari MPLS adalah traffic engineering yang dibuat dengan protokol RSVP. Terdapat protokol baru untuk memberi label pada paket dan mendukung traffic engineering, yaitu Segment Routing. Penelitian ini menganalisis perbandingan performa traffic engineering dengan RSVP dan Segment Routing. Baik pada penerapan RSVP maupun Segment Routing dibuat tunnel untuk jalur utama dan reroute menuju jalur cadangan. Penelitian dilakukan pada emulator EVE-NG dengan mengambil studi kasus topologi backbone di PT ICON+.Hasil penelitian adalah Segment Routing di MPLS menyederhanakan kinerja dari router dalam hal pelabelan dan dalam memelihara Label Switch Path (LSP), tidak membutuhkan protokol signaling. Hasil pengujian latency pada jalur utama, dengan Segment Routing maupun dengan RSVP mempunyai nilai sama. Sedangkan pada jalur cadangan, nilai latency dari Segment Routing lebih kecil, sehingga Segment Routing dapat mengirim data dengan lebih cepat daripada dengan RSVP. Hasil pengujian packet delivery ratio dan packet loss ratio dengan Segment Routing dan dengan RSVP baik di jalur utama maupun jalur cadangan bernilai sama, yaitu 100% dan 0%. Baik pada jalur utama maupun jalur cadangan, penerapan Segment Routing mempunyai nilai throughput yang lebih besar daripada penerapan RSVP, sehingga Segment Routing dapat mengirim data dengan lebih cepat daripada RSVP. Pada kondisi link mengalami kegagalan saat pengujian, keduanya memiliki 1% packet loss, namun perpindahan jalur dilakukan dengan lebih cepat pada Segment Routing.

A Mobile Adhoc Network (MANET) is prone to attacks. Adversaries take hold of the network, thus degrading their performance. Various attacks are prevalent in MANET, out of which Byzantine attack plays a vital role. A node or group of nodes present in the routing path between the source and the destination may be compromised due to Byzantine attack. In this paper, Cohen Kappa Reliability Coefficient based Mitigation (CKRCM) mechanism is proposed to deal with these attacks. The intermediate nodes are monitored by their neighbors for a timestamp. If the monitoring node does not receive an acknowledgment, then the nodes are perceived to be attacked. The trustworthiness of the nodes is built by computing the trusts and reliabilities of the nodes. It is seen that the proposed scheme outperforms the existing scheme in terms of Throughput, Packet Delivery Ratio (PDR) and Packet Loss Ratio (PLR).

Encryption Algorithms

With the emerging technology connected with the internet, there is one constant issue related to that is data security. The only solution with which this issue can be resolved at a limit and can be used to protect the data is various algorithms for encryption. Though different approaches were used for the same, Cryptography seems to be efficiently protecting the data while transmitting in network from sender to receiver. Firstly the data is encrypted before sending to receiver using the most secure and reliable encryption algorithm. Secondly, at the receiver end it can be decrypted using the same decryption algorithm. Only receiver will have the key with which the data can be decrypted. In this paper, AES, DSS and RSA algorithms were implemented. These algorithms are encryption algorithms which perform encoding and decoding of data, to be sent from sender to receiver, using the keys. Each have different criteria for encryption and are then compared based on different parameters viz. delay, throughput, PDR is an acronym for packet delivery ratio, PLR represents packet loss ratio and RPC denotes Received Packet Count. The results in the form of graphs are given to analyze the security provided by each algorithm.

The volume of healthcare information is rapidly growing. Collecting and securing information gathered through a Wireless Sensor Network (WSN) is an open challenge. The integrity and confidentiality of the information is to be ensured, failing to do which will lead to fatal consequences. Further, conserving energy is a challenge in WSN. Hence, in this paper a Secured Energy Aware (SEA) scheme is proposed. Only authenticated nodes communicate to the Fusion Centres (FCs) which collect the data and forward to the Sink or other FCs, thus avoiding redundancy. The propounded scheme offers better results in contrast to the existing scheme in terms of Packet Delivery Ratio (PDR), Throughput, Residual Energy, Packet Loss Ratio (PLR) and Routing Overhead.

Wireless sensor networks (WSNs) establish a new popular of ambient supervision with many latent packages. The environment of wireless sensor networks prone to different forms of attacks as networks are prepared in open and unsecured surroundings. This paper analyses the overall performance of AODV whilst attacked by black hole, through varying the mobility of the nodes within the community. The overall performance metrics which can be used to do the analysis are LPR, packet delivery ratio & Packet loss. The simulation consequences display that the overall performance of each AODV degrades in the presence of black hole attack.

This paper proposes an improved Traffic Class Prioritization based Carrier Sense Multiple Access/Collision Avoidance (TCP-CSMA/CA) scheme for prioritized channel access to heterogenous-natured Bio-Medical Sensor Nodes (BMSNs) for IEEE 802.15.4 Medium Access Control (MAC) in intra-Wireless Body Area Networks (WBANs). The main advantage of the scheme is to provide prioritized channel access to heterogeneous-natured BMSNs of different traffic classes with reduced packet delivery delay, packet loss, and energy consumption, and improved throughput and packet delivery ratio (PDR). The prioritized channel access is achieved by assigning a distinct, minimized and prioritized backoff period range to each traffic class in every backoff during contention. In TCP-CSMA/CA, the BMSNs are distributed among four traffic classes based on the existing patient’s data classification. The Backoff Exponent (BE) starts from 1 to remove the repetition of the backoff period range in the third, fourth, and fifth backoffs. Five moderately designed backoff period ranges are proposed to assign a distinct, minimized, and prioritized backoff period range to each traffic class in every backoff during contention. A comprehensive verification using NS-2 was carried out to determine the performance of the TCP-CSMA/CA in terms of packet delivery delay, throughput, PDR, packet loss ratio (PLR) and energy consumption. The results prove that the proposed TCP-CSMA/CA scheme performs better than the IEEE 802.15.4 based PLA-MAC, eMC-MAC, and PG-MAC as it achieves a 47% decrease in the packet delivery delay and a 63% increase in the PDR.
