Simulation Analysis of New 802.11KT MAC Protocol And IEEE 802.11 MAC Protocol for Grid Topology in MANET Using NS-2

This paper compare the performance analysis of newly designed 802.11KT MAC protocol for a mobile ad-hoc network (MANET) communication system which aims to provide low cost, small end to end delay and more throughputs with the existing IEEE 802.11 MAC protocol. Simulation is the main method for evaluating the performance of protocol. It is subjected to comparison of performance of existing IEEE802.11 Mac protocol and new 802.11KT Mac protocol for random topology in MANET. The Adhoc On Demand Distance Vector (AODV) is used as routing protocol with NS-2 simulator. Simulation results indicated that newly designed 802.11KT MAC protocol has better performance than existing IEEE 802.11 MAC protocol

Formulation and characterization of organic- inorganic hybrid film for transdermal drug delivery

A novel organic–inorganic hybrid film-forming gel for transdermal application was developed by poly vinyl alcohol using Di methyl polysiloxane as an inorganic-modifying agent, poly N-vinyl pyrrolidone as a tackifier and PEG 200 as a plasticizer. The hybrid film-forming gel can be directly applied on the skin forms a thin bioadhesive film with transparent and non- greasy feeling. The mechanical and bioadhesive properties of films produced from the hybrid gels were investigated and the results showed that the incorporation of appropriate Di methyl polysiloxane into the PVA matrix significantly improves the mechanical strength and skin adhesion properties of the resulting film.  In conclusion, the bioadhesive films formed from organic–inorganic hybrid gel holds excellent qualities for application on the skin and may provide a promising formulation for transdermal delivery of drugs, especially when the patient acceptability from an aesthetic perspective of the dosage form is a main consideration.&nbsp
