Topology-Aware Multi-cluster Architecture Based on Efficient Index Techniques

چکیده
In this paper, we focus on how to construct an efficient unstructured P2P system. The main contributions of our proposal are two-fold. First, aiming at alleviating the topology mismatch problem between the P2P logical overlay network and the physical underlying network, we proposed a Topology-aware Multi-cluster Overlay (TMO) architecture where peers self-organize into clusters based on network locality. Second, in order to further improve the search efficiency of the TMO architecture, we present two novel index techniques, namely, cluster-index technique and topic-index technique. The two different techniques are highly effective in different application domains in which the TMO architecture is deployed. The simulation results indicate that our proposed schemes are efficient in both resource usage and data retrieval.

TAC: A Topology-Aware Chord-based Peer-to-Peer Network
Among structured Peer-to-Peer systems, Chord has a general popularity due to its salient features like simplicity, high scalability, small path length with respect to network size, and flexibility on node join and departure. However, Chord doesn’t take into account the topology of underlying physical network when a new node is being added to the system, thus resulting in high routing late...

Due to the resource constraint and dynamic parameters, reducing energy consumption became the most important issues of wireless sensor networks topology design. All proposed hierarchy methods cluster a WSN in different cluster layers in one step of evolutionary algorithm usage with complicated parameters which may lead to reducing efficiency and performance. In fact, in WSNs topology, increasin...
متن کاملAMHC: Adaptive Multi-Hop Clustering based Resource Discovery Architecture for Large Scale MANETs
In this study we propose an efficient clustering protocol called AMHC used for resource discovery in large scale Mobile Ad hoc Networks (MANETs). AMHC is an Adaptive Multi-Hop Clustering generating several non-overlapping network localities (clusters) with explicit elected cluster-heads. Every cluster member is on average d hops away from its cluster-head, where d is an integer parameter for th...
