The accuracy of such feedback is paramount to the mobile search user. However, automating SMS-based information search and retrieval poses significant challenges because of the inherent noise in SMS communication. First, in this paper an architecture is proposed for the implementation of the retrieval process, and second, an algorithm is developed for the best-ranked question-answer pair retrieval. We present an algorithm that assists in the selection of the best FAQ-query after the ranking of the query-answer pair. Results are generated based on the ranking of the FAQ-query. Our algorithm gives a better result in terms of average precision and recall when compared with the naïve retrieval algorithm.

Its enormous pervasiveness has created a great advantage for its use as a technological tool applicable to overcome the challenges of information dissemination regarding burning issues, advertisement, and health related matters. Short message services (SMS), an integral functional part of cell phones, can be turned into a major tool for accessing databases of information on HIV/AIDS as appreciable percentage of the youth embrace the technology. The common features by the users of the unique language are the un-grammatical structure, convenience of spelling, homophony of words and alphanumeric mix up of the arrangement of words. This proves it to be difficult to serve as query in the search engine architecture. In this work SMS query was used for information accessing in Frequently Asked Question FAQ system under a specified medical domain. Finally, when the developed system was measured in terms of proximity to the answer retrieved remarkable results were observed..

Clustering is one of the routing techniques that have been using to minimize sensor nodes' energy consumption during operation. In this paper, A Novel Clustering Algorithm for Energy Efficiency in Wireless Sensor Networks (ANCAEE) has been proposed. The algorithm achieves good performance in terms of minimizing energy consumption during data transmission and energy consumptions are distributed uniformly among all nodes. ANCAEE uses a new method of clusters formation and election of cluster heads. The algorithm ensures that a node transmits its data to the cluster head with a single hop transmission and cluster heads forward their data to the base station with multi-hop transmissions. Simulation results show that our approach consumes less energy and effectively extends network utilization.

This has significantly influenced the traditional standard way of expressing views from letter writing to a high-tech form of expression known as texting language. In this paper we investigated building a mobile information access system based on SMS queries.

The privacy, integrity and confidentiality of a patient's data are key factors to be considered in the transmission of medical information for use by authorised health-care personnel. Mobile communication has enabled medical consultancy, treatment, drug administration and the provision of laboratory results to take place outside the hospital. With the implementation of electronic patient records and the Internet and Intranets, medical information sharing amongst relevant health-care providers was made possible. But the vital issue in this method of information sharing is security: the patient's privacy, as well as the confidentiality and integrity of the health-care information system, should not be compromised. We examine various ways of ensuring the security and privacy of a patient's electronic medical information in order to ensure the integrity and confidentiality of the information.

Concealment of secret messages inside a natural language, known as steganography, has been in existence as early as the 16 th century. However, the increase in electronic/digital information transmission and distribution has resulted in the spread of watermarking from ordinary text to multimedia transmission. In this paper, we review various approaches and methods that have been used to conceal and preserve messages. Examples of real-world applications are also discussed.

The infection rate is continues to grow, in particular, among the young adults. Cell phones have been identified as one of the tools that can be used to overcome the challenge of information dissemination regarding HIV/AIDS among young adults because of its acceptability within this age group. Access to appropriate information can be a powerful for prevention and management of many chronic illnesses, including hypertension, diabetes and HIV/AIDS. Within the young adults age group information access by use of Short Messaging Services (SMS) becomes particularly appealing. In this regard, it is proposed to provide access to carefully screened information on HIV/AIDS within the context of frequently asked questions (FAQ) system. However, automating SMS-based information search and retrieval poses significant challenges because of the inherent noise in SMS communications. In the paper, a special corpus of SMS messages was collected based on a standardised question-answer collection. The SMS messages were then analysed, transcribed and classified, with the aim of building a dictionary of SMS-speak to English translations, with reference to HIV/AIDS.

WBANs promise to revolutionize health monitoring. In this paper, medical sensors were used to collect physiological data from patients and transmit it to Intelligent Personal digital Assistant (IPDA) using ZigBee/IEEE802.15.4 standard and to medical server using 3G communications. We introduced priority scheduling and data compression into the system to increase transmission rate of physiological critical signals which improve the bandwidth utilization. It also extends the life time of hand-held personal server by reducing power consumption during transmission.
