Power Aware Transport Protocol for Ad hoc Networks
Neha Bagoria, Renu Bagoria · 2012
An ad hoc network is a network connection temporary designed for a specific purpose like transferring data from one computer to another which does not required router or a based station. Transport layer is the foundation of the Internet, provides end-to-end control and information transfer. Transmission Control Protocol (TCP) is a transport layer protocol and is planned for a wired network that can handle network congestion successfully. It is end-to-end connection oriented transport layer protocol that gives byte stream based service. Because of the characteristics such as lack of infrastructure, mobility, shared channel and limited bandwidth, TCP implementation leads to poor performance in the ad hoc networks. Therefore several transport layer protocols have been designed and developed exclusively for ad hoc networks. Among these protocols ATP (Ad hoc transport protocol) finds to be more suitable for ad hoc networks. ATP, by designed, is an antithesis of TCP and consists of: rate based transmission, quick-start during connection and routing switching, network supported congestion detection and control, no transmission timeouts, and decoupled congestion control and reliability. By designing of ATP, the performance of sending TCP is concentrated but the performance and load of the intermediate node is not considered. In this thesis a simple approach is proposed to address the intermediate node problem by making it to operate in three layers rather than operating in four layers. This enhanced ATP is called as PATPAN (Power Aware Transport Protocol for Ad hoc Network). This enhanced ATP; PATPAN is designed based on two schemes. One is the PATPAN in IP datagram and the other is the PATPAN in data link layer. Both the schemes operate in three layers.
