Efficient routing protocol will receive a prolonged network lifetime. In this paper we propose an energy-efficient multi-hop routing protocol for wireless sensor networks (EEMR). It mainly includes nodes clustering and inter- cluster multi-hop routing selection. In clustering stage, we introduce an uneven clustering mechanism. Cluster heads which are closer(More)
The topological properties of Peer-to-Peer (P2P) overlay networks are critical factors that dominate the performance of these systems. The P2P networks need a topology with arbitrary size and degree, while the Kautz digraph is a topology with good properties such as constant degree and optimal network diameter O(log<sub>d</sub> N). However, the limitation(More)
The topological properties of peer-to-peer (P2P) overlay networks are critical factors that dominate the performance of these systems. The P2P networks need a topology with arbitrary size and degree, while the Kautz digraph is a topology with good properties such as constant degree and optimal network diameter (9(log<sub>d</sub> n).

High delivery ratio with low energy consumption and transmission delay is one of design challenges for wireless sensor network routing protocol. In this paper, we proposed a grid-based distributed multi-hop routing protocol (GDRP) for wireless sensor network. At one time there is only one node is selected as grid head per grid and the remaining nodes(More)
Byzantine faults in a peer-to-peer (P2P) system are resulted from adversarial and inconsistent peer behaviors. Faulty peers can disrupt the routing functions in the peer joining and lookup schemes. Byzantine attackers may collude with each other to paralyze the entire P2P network operations. We discover a novel DHT-based overlay networks (REIK) with(More)
Formal Concept Analysis (FCA) is an effective formal tool for data analysis and knowledge mining. The paper firstly proposed a semi-automatic method, which is based on extended description, is used to translate the original documents into extended many-valued context. Then based on extended many-valued contexts and extended description, the paper presented(More)
In resent years many routing protocols have been proposed for wireless sensor networks, among which the adaptive routing protocols are very attractive because their low routing overhead. In this paper we propose an energy efficient distributed clustering and routing protocol (DCR). It mainly includes distributed nodes clustering and distributed multi-hop(More)
Based on the research and development about Web service, the business platform topology of ac-service flow is deepened from architecture-centric perspective. For Web service’s dynamic composition and self-adaptation meeting user requirement, architecture-centric merging among flows is put forward, in order to get this goal, optimizing previous flow(More)
