To Overcome the Network Performance by Cross-Layer Designing in MANET

Traditional Wired network uses protocol architectures follow the principle of stack layered implemented by ISO/OSI model. ISO/OSI model was developed to support all the standardization of the network architecture using layered model. Initially wireless network also adopts the traditional stack layered architecture from the wired networks. Wireless network performance can be degraded due to the adaptation of the protocols from layered architecture and Transmission control protocol/ Internet Protocol (TCP/IP), which was designed originally for wired network. However, lack of communication between layers limits the performance of such architectures. In this paper a cross layer design is adopted in wireless MANET in order to overcome the network performance problems. Since nowadays wireless networks are becoming very popular technology. In the Mobile Adhoc network, cross-layer design allows the protocol that belong to different layers which cooperate in sharing network-status information while still maintaining the layers separation at the design level. Cross-layer design has been proposed to maintain the functionalities associated to the original layers but to allow communication of protocols crossing different layers.
