The line is the simplest shape that we can draw with the Graphics class. The drawLine () method takes two pair of coordinates (x1, y1) and (y1, y2) as arguments and draws a line between them. It has the following syntax: g.drawLine(x1, y2, x2, y2); // g is the Graphics object passed to paint () method. In practice, the slotted ALOHA protocol has been established to have a maximum throughput efficiency of about 37% compared to the pure ALOHA protocol which has a maximum throughput efficiency of about 18% when G = 1, and is also energy efficient. Consequently, the slotted ALOHA protocol is envisaged to be a promising candidate that can be.

The initial 5 rows of the TCP header are always used. So, minimum length of TCP header = 5 x 4 bytes = 20 bytes. The size of the 6th row representing the Options field vary. The size of Options field can go up to 40 bytes. So, maximum length of TCP header = 20 bytes + 40 bytes = 60 bytes. 100 bits longsize. calculate the maximum throughput for pure aloha network. Solution: In pure aloha, the maximum efficiency is 0.184. Hence effective bandwidth = 0.184 × 56 kbits/sec = 10300 bits/sec. Each station requires 1000 bits / 100 sec = 10 bits/sec. So, N = 10300/10 => 1030 stations. we know that for pure aloha efficiency = G × e − 2 G G×e−2G and in the maximum case we find it.

Question #5 5. MACS/LANS 5.1. Compare and contrast Aloha vs Slotted Aloha. (6) In Pure Aloha, Stations transmit whenever data is available at arbitrary times and Colliding frames are destroyed. While In Slotted Aloha, A station is required to wait for the beginning of the next slot to transmit. The vulnerable period is halved as opposed to Pure Aloha. CSMA / CD allows a station to transmit data if it senses the carrier free. After undergoing collision, station waits for random back off time before transmitting again. Back Off Algorithm is used to calculate back off time. Also Read- Back Off Algorithm. In this article, we will discuss practice problems based on CSMA / CD and Back Off Algorithm. The main Aloha-based protocols can be divided into four subgroups: Pure Aloha (PA), Slotted Aloha (SA), Frame Slotted Aloha (FSA) and Dynamic Frame Slotted Aloha (DFSA) protocols. 3.1. Pure Aloha. Pure Aloha (PA) is one of the simplest anti-collision protocols. It is based on TDMA [21,22]. Whenever tags enter the interrogation zone, they.

Aloha does not avoid hidden or exposed nodes and is generally inefficient in terms of usage of the channel: pure Aloha leads to a maximum efficiency of less than 1/(2e) ≈ 18.5%, compared to a single user system.Slotted Aloha can utilize the channel up to nearly 1/e ≈ 37%.More sophisticated versions of Aloha, called coded slotted Aloha, which rely on the joint detection principle from.

Slotted Aloha was introduced in 1972 by Robert as an improvement over Pure Aloha. In slotted aloha, successful data transmission occurs only when each slot sends just one data frame at a time. The chance of a collision is considerably reduced by doing so. Here, time is divided into discrete intervals called slots, corresponding to a frame. CSMA/CD stands for Carrier Sense Multiple Access/Collision Detection, with collision detection being an extension of the CSMA protocol. This creates a procedure that regulates how communication must take place in a network with a shared transmission medium.The extension also regulates how to proceed if collisions occur i.e. when two or more nodes try to send data packets via the transmission.

The Slotted Aloha protocol involves dividing the time interval into discrete slots and each slot interval corresponds to the time period of one frame. This method requires synchronization between the sending nodes to prevent collisions. There are two different versior.s/types of ALOHA: (i) Pure ALOHA (ii) Slottecl ALOHA (i) Pure ALOHA..
