The Supplementation of Backoff Rules By TDMA Technique to Improve Data Rate in Mobile Adhoc Networks (MANET)

Abstract: Those Networks in which two or more than two mobile nodes are communicating with other are considered to be Mobile networks, Now the Mobile Ad Hoc Networks are the same kind of networks but they can be implemented at the time of disasters or in the military purpose when there is a need of Ad Hoc Networks which can take over the existing Mobile networks, therefore the only reason which gives it the name of Ad Hoc Networks is that is can be implemented anywhere without any centralized infrastructures. Mobile Ad Hoc network represents a system of wireless mobile nodes that can self organize freely and for the temporary purpose in the network technology, they can be applied anywhere as the MANET reduces the complexity of the Infrastructures. Routing traffic between MANET nodes experience collisions, end to end delay (E2E) and total loss of data packets due to limited bandwidth between nodes. These result in poor Quality of Service (QoS) and E2E delay throughput. In this paper we have proposed the application of time division multiple access (TDMA) technique to improve data rate and reduce control and data over-head collisions. We compared the existing normal routing scheme and the TDMA based scheme. TDMA allows a number of clients to access a single radio-frequency channel without interference by allocating unique time slots to each user within each channel, reducing the loss of packets and improving the data rate thereby delivering QoS to the clients
