Abstract

Objectives: Consolidating any two dissimilar networks leads to a formation of a heterogeneous wireless network. Vision to achieve distinct networks to get converged such that characterizing of the upcoming wireless networks becomes a reality. This in turn ushers in vertical handoff such that handoff among different technologies is efficient. And at the same time it is so smooth that naming it as seamless is justifiable. Pragmatic consideration of the network characteristics and the dynamics are very essential to choose one of the best available network handoff decisions. Methods: Stating conventionally, when a mobile client is roaming, a single criterion- for example, received signal strength is employed to realize the vertical handoff. But, single criterion consideration is not sufficient and taking into account of other parameters is needed for a proper handoff decision. The present paper puts forth a strong load balancing algorithm M-OPTF that is based on dynamic weight assignment technique for allocation of fresh calls and handoff calls. Findings: In the present scheme assignment of weight factor is done to attachment points basing on the distribution of load on them. In addition it contains a process for handoff decision that takes into account the velocity of mobile node to do triggering of handoff. The put forth M-OPTF algorithm is compared along with Remote Sensing Systems (RSS) and OPT-F algorithm in this paper. Application/Improvements: The simulation results confirm the fact that M-OPTF algorithm apart from balancing the network load it can effectively decrease congestion in network, reduce the number of handoffs that are unnecessary, and increases the battery life time, thus improve the overall performance of the system.

Abstract

Faculty experienced in teaching first year undergraduates agree that the students' in first year face a number of challenges. First year students are not only developing academically and intellectually, they are also establishing and maintaining good relationship around them, developing an identity, deciding about career and life style and developing integrated philosophy of life.Due to the gap in their school and engineering curriculum, learning the programming subject in their first semester become more conspicuous. In this paper, an attempt has been made to study and investigate various available opportunities and challenges faced by both fresh and experienced faculty to teach the "Computer programming in c language". A study has been conducted which comprises of a set of questions for which a collective response from the end users have been obtained. The results of this study enlighten various key areas to face the challenges and best ways to work with opportunities.

Abstract

"It is not what you teach and how you teach It is what your audience learns"

Recently the millennial learners occupy the classrooms. These learners are filled with their needs and characteristics. They need collaborative learning experiences, quick feedback and have low tolerance for boredom. The main challenge for the faculty is to keep the learners in the classroom fully engaged, challenged and focused. This paper discusses about the characteristics of millennial learners and the way of using technologies to reach the millennial learners in the classroom. The responsibility of the faculty is to create self-learners and life-long learners.
