    Various types of wired and wireless networks and their applications can be seen in many places now-a-days. In the past decade, we have witnessed a significant increase in the number of Internet users and technology hunters. With the aid of wireless communications and demand of flexible anytime, anywhere networking, many types of wireless self-organizing networks have already gained huge popularity among users. For wider support of wireless connectivity and developing easy-to-use technologies, substantial efforts are underway to reduce human intervention in the configuration, formation, and maintenance processes of these networks. Furthermore, different types of distributed computing technologies are widening the scope of our thinking and research issues in networking. The multi-dimensional research issues include wireless and mobility problems, routing protocols and algorithms, resource and service location protocols, performance evaluations of networking systems, ubiquitous systems, context aware ubiquitous environment, mechanisms to improve throughput over wireless links, network management and network security, and other related areas. To meet the vast demand of networking and distributed computing knowledge in the current times, IJIDCS was launched in the year 2010. It is my pleasure to see that the second volume is coming out with some important and solid contributions. The first issue of the second volume includes some of the papers chosen from the 4th International Workshop on Internet and Distributed Computing Systems (IDCS 2011) in conjunction with ICA3PP 2011 conference, held from October 24 to October 26, 2011 in Melbourne, Australia. The selected papers have been considerably extended and revised. Other regular papers are also included to put multi-dimensional fields in one single issue. The topics range from failure detection to secure transactions, processing online documents to complex wireless system and signaling

    The impact of extreme events across the globe is extraordinary which continues to handicap the advancement of the struggling developing societies and threatens most of the industrialized countries in the globe. Various fields of Information and Communication Technology have widely been used for efficient disaster management; but only to a limited extent though, there is a tremendous potential for increasing efficiency and effectiveness in coping with disasters with the utilization of emerging wireless network technologies. Early warning, response to the particular situation and proper recovery are among the main focuses of an efficient disaster management system today. Considering these aspects, in this paper we propose a framework for developing an efficient Disaster Management Communications and Information System (DMCIS) which is basically benefited by the exploitation of the emerging wireless network technologies combined with other networking and data processing technologies.Comment: 6 page

    A Secure Lightweight Approach of Node Membership Verification in Dense HDSN

    Full text link
    In this paper, we consider a particular type of deployment scenario of a distributed sensor network (DSN), where sensors of different types and categories are densely deployed in the same target area. In this network, the sensors are associated with different groups, based on their functional types and after deployment they collaborate with one another in the same group for doing any assigned task for that particular group. We term this sort of DSN as a heterogeneous distributed sensor network (HDSN). Considering this scenario, we propose a secure membership verification mechanism using one-way accumulator (OWA) which ensures that, before collaborating for a particular task, any pair of nodes in the same deployment group can verify each other-s legitimacy of membership. Our scheme also supports addition and deletion of members (nodes) in a particular group in the HDSN. Our analysis shows that, the proposed scheme could work well in conjunction with other security mechanisms for sensor networks and is very effective to resist any adversary-s attempt to be included in a legitimate group in the network.Comment: 6 page

    Atomic-SDN: Is Synchronous Flooding the Solution to Software-Defined Networking in IoT?

    Get PDF
    The adoption of Software Defined Networking (SDN) within traditional networks has provided operators the ability to manage diverse resources and easily reconfigure networks as requirements change. Recent research has extended this concept to IEEE 802.15.4 low-power wireless networks, which form a key component of the Internet of Things (IoT). However, the multiple traffic patterns necessary for SDN control makes it difficult to apply this approach to these highly challenging environments. This paper presents Atomic-SDN, a highly reliable and low-latency solution for SDN in low-power wireless. Atomic-SDN introduces a novel Synchronous Flooding (SF) architecture capable of dynamically configuring SF protocols to satisfy complex SDN control requirements, and draws from the authors' previous experiences in the IEEE EWSN Dependability Competition: where SF solutions have consistently outperformed other entries. Using this approach, Atomic-SDN presents considerable performance gains over other SDN implementations for low-power IoT networks. We evaluate Atomic-SDN through simulation and experimentation, and show how utilizing SF techniques provides latency and reliability guarantees to SDN control operations as the local mesh scales. We compare Atomic-SDN against other SDN implementations based on the IEEE 802.15.4 network stack, and establish that Atomic-SDN improves SDN control by orders-of-magnitude across latency, reliability, and energy-efficiency metrics
