Address Autoconfiguration in IPv6 Networks: Challenges and Countermeasures

The demand for internet and its applications has eventually led to the depletion of the dominant IPv4 addresses. This has resulted in the inevitable need for the next generation Internet Protocol IPv6, which contains an enormous pool of IP addresses. Address Autoconfiguration, a remarkable feature of IPv6 enables a node connected in the network to automatically configure an IP address for its interface and instantly participate in network communications. The Internet Engineering Task Force (IETF) has classified autoconfiguration into Stateless and Stateful mechanisms. Several IPv6 protocols have been employed to achieve autoconfiguration of networks. However, in addition to the excellent competence of this feature, autoconfiguration certainly suffers in terms of security and optimization. This paper attempts to enlighten the need and merits of Address Autoconfiguration and finally highlights the challenges, open issues and countermeasures involved in achieving this in real time environment

Randomize IPv6 Stateless Address Autoconfiguration in None-stable Storage Arduino Devices

<p>The pervasiveness of IoT device requires each device to have a unique address number in order to communicate. Internet Standard specified in RFC4941-Privacy Extension for SLAAC had question raised on the randomness of the IPv6 address generated due to the shortcoming of device random generator algorithm. Improvements to the RFC’s have been proposed and Arduino Uno had been selected as IoT platform since it currently supports IPv6 implementation. An enhancement algorithm was developed. The generated IPv6 address is then tested against ENT Random Test tool for observation and conclusion.</p>

IDHOCNET: A Novel ID Centric Architecture for Ad Hoc Networks

Ad hoc networks lack support of infrastructure and operate in a shared bandwidth wireless environment. Presently, such networks have been realized by various adaptations in Internet Protocol (IP) architecture which was developed for infrastructure oriented hierarchical networks. The IP architecture has its known problem and issues even in infrastructure settings, like IP address overloading, mobility, multihoming, and so forth. Therefore, when such architecture is implemented in ad hoc scenario the problems get multiplied. Due to this fact, ad hoc networks suffer from additional problems like IP address autoconfiguration, service provisioning, efficient bandwidth utilization, and node identification. In this paper we present IDHOCNET which is a novel implementation of service provisioning and application development framework in the ad hoc context. We illustrate a number of implemented features of the architecture which include IP address autoconfiguration, identification of nodes by using real world identifiers, IP based services support in ad hoc networks, and a new class of application known as ID based application. Moreover how identifiers can completely replace the IP addresses to run the IP based applications is shown. It is expected that this work will open new research horizons and paradigms for ad hoc networks.
