Abstract: This paper proposes Multiple Packet Transmission (MPT) to multiple nodes in unidirectional and bi directional peer to peer wireless LAN for efficient downlink performance. This gives users the mobility to move around within a local coverage area and still be connected to the network. In this paper, we study a novel Multiple-Input, Multiple-Output (MIMO) technique called Multiple Packet Transmission (MPT) in unidirectional peer to peer WLAN, with which the sender can send more than one packet to distinct users simultaneously. The existing system was based on the sequence packet transmission method but this will not reduce the downloading time. It depends upon the client-server architecture that network cannot be expanded. The access point can send two packets to two users simultaneously. It depends upon the system hardware requirements. Paper proposes MPT- that is multiple transmission packets. This suggests sending packets to multiple systems simultaneously. In Bi directional P2P WLAN networks are typically used for connecting nodes, largely ad hoc connections. Data, including digital formats such as audio files, and real time data such as telephony traffic, is passed using P2P technology. The security issues in P2P network can be overcome with help of firewalls and TCP ports.
