AbstractNetwork slicing will permit offering to vertical customers tailored end-to-end logical networks in an on-demand fashion, on top of a common telecom infrastructure, achieving a Slices-as-a-Service (SlaaS) business model. This is possible due to the progressive introduction of network softwarization techniques, such as programmability and virtualization, into existing operational networks, enabling dynamic and flexible provision of slices. Those vertical customers could require the control not only of the network functions composing the end-to-end service, but also of the connectivity among them, e.g., for influencing the paths for steering traffic among function instances. However, this can be problematic since decisions from one vertical customer can collide with decisions from others. One aspect not yet sufficiently investigated is how to permit vertical customers to jointly control the service functions and the underlay connectivity, in such a way that could operate the allocated slice as if it was actually a dedicated network entirely for them. This paper explores some architectural proposition in this respect illustrated with some potential use cases and it provides an example of the provision of SlaaS for a vertical customer.

The network security must be taken into consideration in wireless sensor networks. In our project, we take sensor node data falsification (SNDF) attack using malicious nodes and co-operative detection is used. Fusioncentre collects information from the nodes created in a cluster environment and makes a global decision. The protocol used here is Ad-hoc-on demand distance vector[5] (AODV) and the performance analysis is done using parameters such as throughput and End-to-end delay. The stimulation is done in NS2 using network animator and graphical results are taken.The throughput will be increased compared to the existing system whereas End-to-End delay will be decreased.

Demand Routing

In our Study, we Find that Location-Assisted on-Demand Routing (LAOR) Algorithm has Redundancy Control Overhead. Furthermore, LAOR does Not make Full Use of the Effective Information of New Path to Complete the Follow-up Path. to Address these Issues, an Improved Effective on-Demand Routing, Effective Improved on-Demand Routing (EIOR) Algorithm, is Proposed in this Paper. EIOR Makes Full Use of the Information of Control Packet to Update more Routing Paths, Reduces the Control Overhead for Finding Path and Increases the Real Time of Routing Updates. Moreover, EIOR Increases the Probability of Intermediate Satellite Replies Request Instead of the Destination Satellite, which Shortens the Setup Time of Path and Reduces the End-to-End Delay. it also Designs the RREP Immune Mechanism to Reduce the Control Overhead of the Network. Theoretical Analysis and Simulation Results Show that EIOR Outperforms LAOR. the EIOR can Reduce at Least 7% of the Normalized Control Overhead and 4% of the Average End-to-End Delay.

Penelitian ini bertujuan untuk menerapkan dan mengevaluasi protokol Dynamic Mobile Ad-Hoc Network (DYMO) pada sistem monitoring lahan pertanian berbasis jaringan sensor nirkabel. Rancangan jaringan terdiri dari node sensor yang ditempatkan secara statik di lahan pertanian dan node router serta gateway sebagai node bergerak yang dibawa oleh petani/mobil pertanian. Hasil evaluasi menunjukkan bahwa protokol DYMO dapat digunakan pada jaringan sensor nirkabel untuk sistem monitoring lahan pertanian. Evaluasi rancangan dan skenario di atas lingkungan simulasi OPNET memperlihatkan kinerja jaringan menggunakan protokol DYMO dapat diterima. Salah satu pengujian memperlihatkan rata-rata delay pengiriman dan penerimaan data sebesar 10,812506/ms, minimal waktu delay end-to-end pengiriman dan penerimaan node sebesar 19,105028/ms, maksimal sebesar 19,643988/ms, dan rata-rata pengiriman dan penerimaan delay end-to-end yaitu 19,377766/ms, nilai rata-rata throughput sebesar 46.651 bits/sec. Selain itu, evaluasi awal prototip node sensor berbasis XBee pada jarak 120 meter menunjukkan kinerja jaringan seperti kehilangan paket (packet loss) dan kekuatan sinyal yang dapat diterima.

Inter-domain communication in time-sensitive networks (TSN) has been identified as a requirement for various use cases. The TSN Toolbox provides standards for dynamic stream reservations, which is needed for, e.g., batch size 1 production, but these standards do not support the interaction on the control plane between multiple TSN domains. This paper presents control plane mechanisms for multi-domain time sensitive networks (MDTSNs) integrating an east–westbound protocol in the existing TSN control plane, in order to achieve multi-domain on-demand end-to-end bounded-latency TSN streams. Solutions for issues resulting from MDTSN, particularly the inter-domain forwarding offset, are presented. A proof of concept has been implemented and evaluated in a physical MDTSN test environment in order to prove the viability of the mechanisms developed.
