Named data networking for efficient IoT-based disaster management in a smart campus

Disasters are uncertain occasions that can impose a drastic impact on human life and building infrastructures. Information and Communication Technology (ICT) plays a vital role in coping with such situations by enabling and integrating multiple technological resources to develop Disaster Management Systems (DMSs). In this context, a majority of the existing DMSs use networking architectures based upon the Internet Protocol (IP) focusing on location-dependent communications. However, IP-based communications face the limitations of inefficient bandwidth utilization, high processing, data security, and excessive memory intake. To address these issues, Named Data Networking (NDN) has emerged as a promising communication paradigm, which is based on the Information-Centric Networking (ICN) architecture. An NDN is among the self-organizing communication networks that reduces the complexity of networking systems in addition to provide content security. Given this, many NDN-based DMSs have been proposed. The problem with the existing NDN-based DMS is that they use a PULL-based mechanism that ultimately results in higher delay and more energy consumption. In order to cater for time-critical scenarios, emergence-driven network engineering communication and computation models are required. In this paper, a novel DMS is proposed, i.e., Named Data Networking Disaster Management (NDN-DM), where a producer forwards a fire alert message to neighbouring consumers. This makes the nodes converge according to the disaster situation in a more efficient and secure way. Furthermore, we consider a fire scenario in a university campus and mobile nodes in the campus collaborate with each other to manage the fire situation. The proposed framework has been mathematically modeled and formally proved using timed automata-based transition systems and a real-time model checker, respectively. Additionally, the evaluation of the proposed NDM-DM has been performed using NS2. The results prove that the proposed scheme has reduced the end-to-end delay up from 2% to 10% and minimized up to 20% energy consumption, as energy improved from 3% to 20% compared with a state-of-the-art NDN-based DMS

Reliable Multicast in Heterogeneous Mobile Ad-hoc Networks

In disaster scenarios, communication infrastructure could be damaged orcompletely failed. Mobile Ad-hoc Networks (MANETs) can be used to substitutefailed communication devices and thus to enable communication. As group communicationis an important part in disaster scenarios, multicast will be used to addressseveral nodes. In this paper, we propose our new reliable multicast protocol RMDA(Reliable Multicast over Delay Tolerant Mobile Ad hoc Networks). We introducean efficient group management approach and a new method for reliable multicastdelivery over Delay Tolerant Networks. We show, that our protocol is adaptive todifferent kinds of MANETs, e.g. with or without clusterheads, respectively. Forthose without, we use our name resolution over adaptive routing approach

Factors Impacting Key Management Effectiveness in Secured Wireless Networks

The use of a Public Key Infrastructure (PKI) offers a cryptographic solution that can overcome many, but not all, of the MANET security problems. One of the most critical aspects of a PKI system is how well it implements Key Management. Key Management deals with key generation, key storage, key distribution, key updating, key revocation, and certificate service in accordance with security policies over the lifecycle of the cryptography. The approach supported by traditional PKI works well in fixed wired networks, but it may not appropriate for MANET due to the lack of fixed infrastructure to support the PKI. This research seeks to identify best practices in securing networks which may be applied to new network architectures

Scalable and Secure Dynamic Key Management and Channel Aware Routing in Mobile Adhoc Networks

A MANET (Mobile Ad-hoc Network) is an infrastructure-less self configuring wireless networks of routers. Key management is at the center of providing network security via cryptographic mechanisms with a high-availability feature. Dynamic key is the efficient assistance for network scalability. Routing protocol used here is a form of reactive routing called CA-AOMDV and compared with Table driven routing called DSDV. Channel aware routing protocol quality of the channel which can be measured in terms of suitable metrics. This paper leads to an emphasis on Black hole attack and to develop a dynamic key framework using RSA algorithm

An analysis of secure MANET routing features to maintain confidentiality and integrity in IoT routing

The Internet of Things (IoT) is fast becoming a global phenomenon and many issues are arising such as standardization, deployment of IPv6, sensors’ energy requirements and security among others. However, without a secure network routing system IoT nodes will be exposed to malicious activities on the network, data compromises, privacy invasion and even acts of terrorism could be perpetrated via the teeming billions of IoT nodes. Various MANETs secure routing protocols have been proposed by researchers which could be utilized in the development of secure routing protocols for the Internet of things, thus the study of these secure MANET routing protocols will give a direction for the development and incorporation of secure routing in the Internet of Things. This paper surveys secure routing protocols in MANETs while proposing some secure MANET routing features for enshrining confidentiality and integrity in IoT routing. This paper also discusses research trends and future directions in the area of security of IoT networks
