PAPER ONE
The Accuracy of Location Prediction Algorithms Based on Markovian Mobility Models
Péter Fülöp, Budapest University of Technology and Economics, Hungary Sándor Imre, Budapest University of Technology and Economics, Hungary Sándor Szabó, Budapest University of Technology and Economics, Hungary Tamás Szálka, Budapest University of Technology and Economics, Hungary
The efficient dimensioning of cellular wireless access networks depends highly on the accuracy of the underlying mathematical models of user distribution and traffic estimations. The optimal placement/deployment of e.g. UMTS, IEEE 802.16 WiMAX base stations or IEEE 802.11 WLAN access points is based on user distribution and traffic characteristics in the service area. In this paper, the authors focus on the tradeoff between the accuracy and the complexity of the mathematical models used to describe user movements in the network. The authors propose a novel Markov chain based model capable of utilizing user�s movement history. This article analyzes the complexity of the proposed model and justifies the accuracy by means of simulation.

PAPER TWO
Optimizing Message Verbosity and Energy Consumption in Secured Wireless Mobile Networks
P. P. Abdul Haleem, National Institute of Technology Calicut, India M. P. Sebastian, National Institute of Technology Calicut, India
This article presents a method for reducing the verbosity of messages in the constrained wireless mobile networks. Wireless mobile devices, especially low cost devices, are stifled by limited resources such as battery power, screen size, input, memory, and processors. The relevance of low cost wireless mobile devices in penetrating to third world market demands for a cost effective messaging format that fits in the constrained wireless environment. The authors offer a proposed scheme based on YAML AinŽ Markup Language (YAML), a user friendly and light weight messaging format. This article proposes a measure to reduce the message size and energy consumption together with secure processing.

PAPER THREE
Optimal Spectral Resolution in Speaker Authentication Application in Noisy Environment and Telephony
Siham Ouamour, USTHB University, Algeria Halim Sayoud, University of Bab-Ezzouar, Algeria Mhania Guerti, ENS.Polytechnique, Algeria
This article deals with the problem of speaker characterization, for which the principal interest is the improvement of the techniques of speaker authentication. For this purpose, the authors investigate the effect of spectral resolution in the speaker authentication performance. This investigation employs an approach based on the second order statistical measures using mel frequency spectral coefficients (MFSC) and seeks the best spectral resolution. Experiments are done on microphonic and telephonic speech signals with several MFSC dimensions and several types of noises.

PAPER FOUR
Improving Energy Efficiency and Throughput in Heterogeneous Mobile Ad Hoc Networks
Manu.J.Pillai, Kerala University, India M. P. Sebastian, National Institute of Technology Calicut, India
Nodes are expected to transmit at different power levels in heterogeneous mobile adhoc networks, thus leading to communication links of different length. Conventional MAC protocols that unconditionally presume that links are bi-directional and with unvarying energy distribution may not succeed or execute badly under such circumstances. Interference and signal loss resulting out of distance and fading diminish the entire throughput attained in heterogeneous networks to a greater extent. This article presents a MAC protocol, which adaptively transmits data frames using either the energy efficient nodes or a list of high data rate assistant nodes. In addition, a cross-layer based energy level on-demand routing protocol that adaptively regulates the transmission rate on basis of congestion is projected.

PAPER FIVE
Mobile Community Networks: Evolution and Challenges
Vijayan Sugumaran, Oakland University, USA Shriram Raghunathan, B. S. Abdur Rahman University, India K. Vivekanandan, Bharathiar University, India
The evolution of mobile devices has opened new opportunities for collaboration and communication. Instant connectivity, portability, rapidly reducing costs, etc. are some of the drivers for this change. Mobile devices have lower processing power and memory capabilities and deal with varying network conditions. Notwithstanding the above, mobile communities have emerged as a significant domain of research in their own right akin to the online (virtual) communities. This article traces the factors contributing to the proliferation of mobile communities and places the mobile community networks in a current and future perspective. This article proposes an architecture for mobile community networks and discusses the challenges in implementing such network.
