Prior Analysis

The Skip-link architecture dynamically reconfigures Network-on-Chip (NoC) topologies in order to reduce the overall switching activity in many-core systems. The proposed architecture allows the creation of long-range Skip-links at runtime to reduce the logical distance between frequently communicating nodes. This offers a number of advantages over existing methods of creating optimised topologies already present in research, such as the Reconfigurable NoC (ReNoC) architecture and static Long-Range Link (LRL) insertion. This architecture monitors traffic behaviour and optimises the mesh topology without prior analysis of communications behaviour, and is thus applicable to all applications. The technique described here does not utilise a master node, and each router acts independently. The architecture is thus scalable to future many-core networks. The authors evaluate the performance using a cycle-accurate simulator with synthetic traffic patterns and compare the results to a mesh architecture, demonstrating logical hop count reductions of 12-17%. Coupled with this, up to a doubling in critical load is observed, and the potential for 10% energy reductions on a 16×16 node network.

Specific Implementation

Today, telecommunication operators are facing an epochal challenge due to the need of higher reconfigurability, flexibility, and dynamicity for their networks. In the latest years, this necessity has been addressed by the introduction of Software-Defined Networking (SDN), mainly in the fields of data centers and core networks. The present work introduces a unified metro-access optical network architecture based on some features inspired by SDN models. The essential aim is to enable bandwidth shared among different passive optical networks (PONs) in order to achieve higher adaptability to increasingly migratory and volatile traffic patterns. Even if the present work is mainly focused on the architecture, several hints for specific implementation of the network nodes are detailed as well in order to demonstrate its feasibility. Several numerical simulations have been performed to assess the performance of the proposed solution both about physical effects and about quality of service. Bit error ratio degradation due to physical impairments has been evaluated and traffic congestion has been estimated in terms of burst loss probability and average throughput.

Network Topologies

IOT is going to offer large number of applications in various environments for improving the quality of our lives. Routing issues become more and more challenging for low-power and lossy radio-links, multi-hop mesh topologies, the battery supplied nodes and frequently changed network topologies. So that IOT routing protocols has some challenges like traffic Patterns, Energy efficiency, Scalability, Mobility Energy-aware metrics for routing protocol in IOT are node energy, throughput, latency, link quality. The multimedia transmission in IOT depends on a routing protocol to determine stable and resource efficient path, and to provide varying levels of QoS/QoE based on different requirements. The Quality- of-Service (QoS)/Quality-of- experience (QoE ) guarantee for multimedia in internet of things . The current research and development activities have been restricted to scalar sensor data based IOT systems and overlooked the challenges of provisioning multimedia devices over IOT.
