Analysis of Hierarchical Mobile IP Based Fast Mobility Management Schemes

Abstract: Mobility management in the wireless domain is a challenging issue for the next generation networks. Frequent change of network requires a new IP address to route packets from one host to another. It is done by sending the mobile node (MN) binding update to the Home Agent (HA) when the Care of address (CoA) gets changed. This registration requires large number of location updates, excessive signaling overhead and service delay. This problem is solved by Hierarchical Mobile IP (HMIP) protocol using the concept of hierarchy of Foreign Agent and the Gateway Foreign Agent /Mobility Anchor point to localize the registration information. This article presents an overview of set of HMIP based mobility protocols such as HMIP, PHMIP, RHMIP, DHMIP, FFHMIP, MIFA etc. that will play an important role in IP based mobility management. We analyze the advantages and disadvantages of theses protocols in the context of handoff latency and signaling overhead. Further, we propose a network model by removing the binding update with HA and simulate its performance in OPNET simulator. The simulation results show that our proposed mechanism achieve better performance than other protocols.

Brain Computer Interface: A Review

Abstract: Brain-computer interface (BCI) enables their users to use brain signals instead of the brain’s normal peripheral nerve and muscle output paths to communicate or control external devices. Several methods can be used to obtain data from the brain sensors that basically monitor physical processes Brain computer interface technology is an emerging area of research with several applications in medical fields. In this review, we discuss the current status and future prospects of BCI technology and its applications in several fields. We will define BCI, examine BCI-related signals from the human brain, and describe the functional components of BCI. We will also review the different applications of BCI technologies in the field of medicine, in entertainment and games, safety and security and in biomedical. Finally, we will discuss the current restrictions of BCI technology, obstacles to its widespread clinical application, and expectations for the future.

Production of Lipase and Phospholipase Enzymes from Pseudomonas sp. and Their Action on Phospholipids

Abstract: One bacterial strain was isolated from soyphospholipid enriched media of pseudomonas group and cultured in peptone, yeast extract and beef extract containing media. The kinds of enzyme from the bacteria appeared to have both lipase and phospholipase activity and specificity as evident from their mode of action on triacylglyceride and phospholipid as well.
