Performance enhancement of network and transport layer protocols in MANETS

Abstract

The continuing rampant necessitate for the wireless communication and related dynamic applications demands for transmission and routing methodologies capable of surviving network breakdowns and maintain superior Quality of Service and Experience to users Mobile AdHoc Network MANETs has been recognized as the most active form of a wireless network type which is decentralized in nature and does not rely on any infrastructure support Hence, MANETs successfully helps in making communication possible where it is almost impossible to However, its fairly challenging to envisage effective performance considering complete network stack in complex scenarios Additionally appropriate management of multiple flows sharing the common resource bandwidth makes these networks even more complex Moreover due to their vigorous characteristics such as autonomous and decentralized working mobility multihop routing capabilities battery constraint operations and lack of predefined infrastructure support posses many complexities in MANETs Furthermore these mentioned problems drastically influence the transport and routing layer performance in MANETs In the past few years Layer4 protocols use a single path communication between numerous applications However they are not capable enough to keep up with increasingly growing traffic highly dynamic characteristics of the wireless network, and do not offer an appropriate stability as well Moreover single path communication is not able to offer the significant fault tolerance demands to multiple resource constraint bandwidth and throughput applications results in degrading Quality of Service and Experience to users Consequently this insufficiency has led to the explosion of multipath communication technology in trend Nonetheless routing over multiple paths fairness and traffic splitting are the problems associated with the multipath communication technology Apart from these challenges some other issues such as path dissimilar characteristics and packet reordering problem persist with multipath
