EXISTING SYSTEM

               PROPOSED SYSTEM

EXISTING CONCEPT:-

Under the assumption of single-packet reception capability, much effort has been devoted to figuring out the optimal transmission probability of a node.

The performance of random access protocols with single packet reception has been extensively investigated and well understood during the last decade.

 PROPOSED CONCEPT:-

The performance of random access protocols such as the slotted-ALOHA is characterized by the transmission probability of a node. System throughput depends on the transmission probability of a node.

We can expect optimal transmission probability that maximizes the system throughput.

EXISTING ALGORITHM :-

Closed Loop Control-Collision Non-Detect (CLC-CND) algorithm

PROPOSED ALGORITHM :-

Anticollision algorithms.

CSMA

ALGORITHM DEFINITION:-

The above model means that the AP can receive up to M packets simultaneously, and concurrent transmissions more than M packets result in collisions and so all the packets are lost

ALGORITHM  DEFINITION:-

sense multiple access (CSMA) is a probabilistic media access control (MAC) protocol in which a node verifies the absence of other traffic before transmitting on a shared transmission medium, such as an electrical bus, or a band of the electromagnetic spectrum.

DRAWBACKS:-

MAC protocols with conventional single-packet reception.

The performance of random access protocols with single packet reception has been extensively investigated and well understood during the last decade.

ADVANTAGES:-

Fast transformation of data from sender to receiver.

The result reveals that the optimal transmission probability in the slotted-Aloha protocol with Multi Packet Reception.
