Routers in Internet face the problem of congestion due to the increased use of Internet. AQM algorithm is a solution to the problem of congestion control in the Internet routers. As data traffic is bursty in routers, burstiness must be handled without comprising the high link utilization and low queuing delay. Congested link causes many problems such as large delay, unfairness among flows, underutilization of the link and packet drops in burst. There are various existing algorithms that have been evolved over the past few years to solve these problems of congestion in routers. RED based algorithms use queue length as congestion indicator while some of them use flow information for more accurate congestion indication. In this paper, we propose an AQM scheme that considers only the advantages of both these queue length based and flow based algorithm and satisfies the QOS requirements of the network. This proposed scheme aims to provide good service under heavy load and shields the responsive flows form unresponsive flows to offer a good QOS to all users.Keywords

Miraculous growth in mobile technology increases the mobile usage day by day. Mobile data traffic and the limitation of power backup are still the major problem in disseminating consistent data on mobile database environment. In this paper, the author propose a consistent replicated mobile data broadcast algorithm(CRMB) to improve the performance of broadcast approach by providing high data availability, consistency and currency with the minimum data access delay and uplink communication. When an update transaction is executed on replicated mobile database environment, it preserves the consistency among the fixed host server, replica servers and the read-write mobile clients. The implementation results show that the performance of proposed approach is better in most cases. Key features of the proposed approach are:
- It disseminates consistent data quickly to all mobile clients in the same order in which they were updated through minimum bandwidth communication
- It allows the mobile clients to get broadcasted data items from any nearest replica server without contacting the server.

E-learning plays an important role in providing required and well formed knowledge to a learner. The medium of e- learning has achieved advancement in various fields such as adaptive e-learning systems. The need for enhancing e-learning semantically can enhance the retrieval and adaptability of the learning curriculum. This paper provides a semantically enhanced module based e-learning for computer science programme on a learnercentric perspective. The learners are categorized based on their proficiency for providing personalized learning environment for users. Learning disorders on the platform of e-learning still require lots of research. Therefore, this paper also provides a personalized assessment theoretical model for alphabet learning with learning objects for children’s who face dyslexia.Keywords
