This paper presents a hybrid optimization algorithm, referred to as hybrid spiral dynamics bacterial chemotaxis (HSDBC) algorithm. HSDBC synergizes bacterial foraging algorithm (BFA) chemotaxis strategy and spiral dynamics algorithm (SDA). The original BFA has higher convergence speed while SDA has better accuracy and stable convergence when approaching the optimum value. This hybrid approach preserves...
The gray codes are named after Frank Gray, who patented (U.S. Patent 2 632 058) the use of them in shaft encoders in 1953. Because of the reflection property of the code, sometimes the term Gray code is used to refer to reflected binary codes. The Gray codes are cycling in nature and maintain the unit hamming distance between one code word to the next code word. To visualize the attributes of reflection...
This paper presents structures of 8-bit Cyclic Redundancy Check (CRC). The CRC structures are implemented using Linear Feedback Shift Registers (LFSRs) along with Exclusive-OR logic gates. In these structures bank of External Exclusive-ORs (EEORs) are used. To equip the LFSR with primitive characteristic polynomial an algorithmic based search procedure is developed to provide the error detection and...
The development of the security layers between the wireless terminals is one of the biggest trends in wireless communications. Bluetooth can be described as the short range and the low power supplements that holds the connection protocol through various devices. This paper presents the development of a secure wireless connection terminals on a field programmable gate array (FPGA). The wireless connection...
