On IoT Programming

Abstract: This paper provides an overview of challenges for Internet of Things programming. In this article we discuss system software models and solutions, rather than network related aspects. It continues our series of publications about M2M systems, existing and upcoming system software platforms for M2M applications. We discuss here such issues for IoT systems as latency, power limitation, reliability (unreliability), network topology related effects as well as data processing in IoT applications. In this paper, we would like to discuss some challenges associated with Internet of Things (IoT) programming. In this article we discuss system software models and solutions, rather than network related aspects. This paper continues our series of publications about software aspects of M2M and IoT. In our first paper (1) we discussed the problems with the unified standards with Machine to Machine communications (M2M). We concluded that the current development misses the larger point of how M2M services and products get created and deployed. In many cases, developers either have to use some predefined platform and be locked with its restriction or build a system completely from scratch. For M2M and Internet of Things products to be successful, interfaces must be simple. The complexity that lies underneath should be completely hidden. As seems to us, at the current stage the existing solutions very often just increase the complexity. The complexity of existing approaches we've discussed also in our paper (2). It raises the following question: do we really need Application Program Interfaces (API) always, or our goal could be described as Data Program Interfaces (DPI)? We can describe DPI as an interface at the edge of an IoT device that exposes and consumes data. IoT devices very often do not support commands (instructions). Many of sensors just provide some data and nothing more. This simple step (refusal to support API) can seriously simplify the interaction with the devices. DPI's are much simpler, of course. And what is more important - they can create a unified API for all devices. The process of reading data can be similar for all devices. As usual, we can pass data interpretation (translation) to the end-user devices. And our

Micro-service Architecture for Emerging Telecom Applications

Abstract: In this paper, we would like to discuss software standards in the connection with the development of emerging telecom applications. Emerging (military) telecom applications present one of the biggest challenges for the developers (design and development) and telecom providers (deployment and maintenance). It is especially true in the context of transition from TDM to IP networks. This transition may bring own challenges associated with the priorities in data transmission, security, etc. We describe two biggest telecom related examples (GIG and FI-WARE), discuss the challenges and propose directions for software standards development and deployment

A Novel Replica of High Dimensional Data Using Feature Subset Selection Algorithm

Abstract: In the high dimensional data the dimensional reduction is an important factor, for that purpose the clustering based feature subset selection algorithm is proposed in this paper. The features has been clustered according to the class labels. The Relevance of the clustered features has been evaluated. The correlation of the relevant clustered feature are then evaluated. Based on the correlation evaluation the Minimum Spanning Tree (MST) has been generated. The representatives of each class has been identified by the MST. The effectiveness is determined in terms of time required to find the subset of feature and the efficiency is determined terms of quality of the subset. By comparing the proposed algorithm with the existing feature selection algorithms like FCBF, reliefF, CFS etc with respect to the four classification algorithms namely Naive Bayer, the tree based c4.5, the instance based IB1 and rule based RIPPER the proposed algorithm is better in terms of efficiency and accuracy. The results are computed with various types of data set.
