Frequencies of propagation of electromagnetic waves in a hexagonal waveguide
In this work, cut-off frequencies of propagation of electromagnetic waves in a hexagonal waveguide are calculated using two-dimensional (2-D) finite element method. The numerical approach is a standard one and involves six finite elements. A new type of ...
Secure and highly efficient three level key management scheme for MANET
MANET(Moving Ad hoc Network) is a convenient infrastructure-less communication network which is commonly susceptible to various attacks. Many key management schemes for MANETs are presented to solve various security problems. Identity (ID)-based ...
Selection of polynomials for cyclic redundancy check for the use of high speed embedded: an algorithmic procedure
Cyclic Redundancy Check (CRC) technique which is widely used tools in globally standardized telecommunications systems for dealing with data errors detection and correction have not been fully standardized. Most of the CRCs in current use have some ...
