Introduction to An Advanced Mac Protocol MIMO WLANS Project:

A format where digital messages are exchanged inside a system network is called communication protocol, MAC or Media access control is such a data communication protocol which acts as a data link layer sub layer. It is part of a 7 layer computer network OSI model. The physical layer of the network and the logical link layer use MAC as an interface between the two.

Communication service by MAC Channel includes

• Unicast
• Multicast
• Broadcast

If the two devices are connected in a network through a wireless medium it is called a wireless LAN network or WLAN network. There are different types of wireless technology used around the globe in WLAN’s. In order to better the connection capacity and the range among the access point and a client station, a new wireless technology is used called MIMO or multiple input or multiple output wireless networks. For this type of wireless communication networks, the standard used are mostly specified in IEEE 802.11 specs.

This project deals with drastically lessens the chance of collision across a network during the case of multi user access streams, CSMA/CA scheme which is advanced is suggested for solving the constant collision problem.  The main disadvantage or drawback of the 1EEE 802.11 system was it had huge block delays during communication and no throughput was happening.

The proposed system displayed an encouraging throughput and there was a considerably improvement in the delay factor. Moreover the proposed system protocol helped in processing large number of data requirements rate applications across a host of networks. The constraint which has very less delay is also managed as effectively with this new protocol. A control channel is not required at all for the transmission of data, moreover the probability of collision is so much less as its dependability is on clusters contending.

Introduction to Designing Reduced Instruction Set computer (RISC) Processor Using VHDL Project: 

The designing of super-efficient computer processors and accelerators for hardware is done mainly by reducing the control of the compiler hardware to a low level.  RISC computing or reduced instruction set computing is a design of the CPU that can provide higher performance by simplified instructions which leads to a faster execution.

RISC is a system that allows the usage of optimized set of instruction to the highest level and uses the load/store architecture. Primitive computer languages were used to analyze the sequential programs, much similarly standard language are used to define the digital circuits. Hardware description language or HDL is used in hardware elements to concurrent the process model in it.  The cost effectiveness of the RISC model has impressed many of those who design a compact hardware.

The first step in designing is to test a program to check the input and output in the design module under various conditions. A simulator tool called Verilog simulator verifies the functioning of the design. Algorithm and logical unit will be synthesized and generation of a netlistwill happen which in turn will be transformed into a programmable logic device or PLD image file. The test jig is wired and verified after the PLD files are programmed in a device called CPLD.

Verilog HDL has many pros comparing to the other HDL’s. No special technology is selected while designing, also redesigning the circuit also don’t emerge as a case. The design is implemented into the tool and a gate level net list is created, the verification process is done in the design stage itself eliminating the errors and cons there and then itself.

The functional units of the machine:

Processor

Controller

Memory

Various functions includes data operations on ALU, storage, instruction, address registers and program counter content changing, altering memory content , data retrieval , bus movement controls etc.

Introduction to A Secure Communication Protocol For Ad Hoc Networks Java Project:

The biggest problem everyone faces while sending or sharing data is the security issue associated with the transfer. The chance of infiltration is higher in a less secured network and as a result there would be loss of important confidential data. The ad-hoc network is independent of any fixed infrastructure and it’s the each individual node in it that works as a router by managing and transferring the data among each other.

There should be a highly secured and safe protocol for communication between each of these nodes. This topic deals with such innovative security measure called clustering adapted for such ad-hoc networks. The data packets are shared between two nodes inside and among these clusters. A head node is selected to execute all important functions and uses various technological processes such as encryption and cryptography to make the whole system more authentic, secure and scalable. 

The data packets are usually vulnerable to hacker attacks and it is extremely important to protect them from such malicious attacks. Techniques such as symmetric key cryptography and authentication techniques such as Kerberos authentication are used to manage the integrity and transparency of these data packets. A method and an algorithm which is randomized to control access to channel broadcast is also another technique used to secure communication protocol of these types of ad-hoc networks.

A distributed clustering algorithm is also used to help cluster the nodes. A leader is selected within a cluster and other nodes maintain close proximity to this leader in cluster leader based scheme which reduces the cluster overhead considerably well. The two different algorithms namely randomized channel control access and distributed clustering are also used for increasing the security of the protocol. By using these methods the overall efficiency of the ad-hoc network increases and the overhead considerably decreases.
