Editorial to special issue: computer and network applications for ubiquitous computing

Abstract

We are very happy to publish this special issue of the computing published by Springer. This issue contains nine articles come from various countries, among which we mention Spain, Australia, South Korea, Kingdom of Saudi Arabia, India, United Kingdom, China, Japan, and Iran. Achieving such a high quality of papers would have been impossible without the huge work that was undertaken by the editorial board members and external reviewers. We take this opportunity to thank them for their great support and cooperation. In “E-D2HCP: enhanced distributed dynamic host configuration protocol”, authors proposed a stateful scheme for dynamic allocation of IP addresses inMANETs entitled extended distributed dynamic host configuration protocol because it is based on a previous piece of work (D2CHP). This work proposed a stateful auto-configuration protocol that guarantees the uniqueness of IP addresses under awide variety of network conditions such as missing messages and merging and partitioning of networks. Authors showed thatChen et al.’s schemehas somedrawbacks and the improvement proposed by Truong et al. is still insecure and vulnerable in “More efficient keyhash based fingerprint remote authentication scheme using mobile device”. Authors proposed an improved scheme which overcomes the flaws and inherits the goodness of both the schemes, Chen et al.’s scheme and Truong et al.’s scheme.
