Enhancement Throughput of Adhoc Network using DSDMAC Protocol

Sridhara S.B, Prof B.Ramesh

An Adhoc network refers to a network with no fixed infrastructure and the nodes are assumed to be capable of moving either on their own or carried by the user. However in practice deafness, hidden terminal and exposed terminal problems are some of the common problems causing the overall degradation of the adhoc network. In our project we have developed a novel scheme for Random access based Medium Access control Protocol called “Dual sensing directional medium access control protocol” which makes use of two types of antennas namely directional and omnidirectional for carrier sensing in Medium Access Control protocol. This scheme makes use of one channel for data signal and another channel for control signal carrier sensing. BT1 and BT2 are two different patterns of non interfering sine wave signals which are used for the other nodes to be aware of an ongoing transmission. This scheme enhances the network throughput and lowers delay utilizing the spatial multiplexing gain of the antenna. Network simulator is used in the simulation of our project and the results are presented in the form of snapshots
