These articles have been peer-reviewed and accepted for publication but are pending final changes, are not yet published and may not appear here in their final order of publication until they are assigned to issues. Therefore, the content conforms to our standards but the presentation (e.g. typesetting and proof-reading) is not necessarily up to the Inderscience standard. Additionally, titles, authors, abstracts and keywords may change before publication. Articles will not be published until the final proofs are validated by their authors.

Abstract: The internet protocol television took the advantage of the convergence of internet services to provide seamless interactivity, time shifting, video on demand and pay per view services. However, zapping delay is a critical problem that deters the switching intention of terrestrial subscribers and widespread of internet protocol television services. This article presents the design of an effective two-list group program driven algorithm that minimizes the channel seek distance and channel seek time in order to reduce zapping delay in internet protocol television. The algorithm groups similar channel programs in related service categories such as news, movies, sports, music and documentary to make it easier for channels with similarly aired programs to be identified rapidly among several channels that an internet protocol television offers. The simulated results of the proposed algorithm show that the average seek distance is significantly reduced by 58% when benchmarked with the state of the art numerical ordering, frequency circular ordering and frequency interleaved ordering.

Packet Loss Minimizing Approach Based on Traffic Prediction for Multi-streaming Communication over MANET
by Vivekananda GN, Chenna Reddy P
Abstract: Wireless networks are extensively used for communication. Most of the devices that we use for communication are equipped with the wireless network interface and are capable of streaming data efficiently to the device within the communication range. Stream Control Transmission Protocol (SCTP) is designed for multi-streaming service. In this paper, a Packet Loss Minimizing Approach (PLMA-SCTP) based on traffic prediction for multi-streaming application is proposed for the Mobile Ad hoc Networks (MANETs) environment. The objective is to reduce data loss and delay in multi-streaming communication. The PLMA-SCTP method aims to provide an efficient route with optimal overhead and delay. Our simulation studies prove that PLMA-SCTP improves the various performance metrics of multi-streaming applications.
