The popularity of community-centric applications has rapidly grown during the recent years. In this paper, we evaluate the robustness of a P2P community management system, where communities are established as autonomous DHT overlays that are advertised in a global DHT overlay. The evaluation is based on the experimental measurements conducted using a DHT-based protocol with two DHT algorithms called...
Delay Tolerant Network (DTN) is a network in which end-to-end connectivity may not be guaranteed because of the frequent and long duration partitions. SMART routing, which is a selective controlled-flooding scheme, utilizes travel companions of the destinations and improves the delivery opportunities, but its flooding overhead can be further controlled. In this paper, we propose A-SMART routing which...

In this paper, we propose a routing protocol for disconnected ad hoc networks where most nodes tend to move about in groups. The proposed protocol works by identifying groups using an efficient distributed group membership protocol, and then routing at the group level, rather than at the node level. The protocol is designed so that existing concepts of routing in disconnected ad hoc networks can be...
With the advent of concept of trustworthy networks, discussions on its supporting technologies have become a new focus of research. This paper proposes a new trust mechanism for the routing systems of trustworthy networks. Presently, study of trust is mostly based on the trust of "hard" security. While behavior trust is classified into the category of "soft" security. This paper...
