title = "Packet recycling and delayed ACK for improving the performance of TCP over MANETs",
abstract = "Most of the schemes that were proposed to improve the performance of transmission control protocol (TCP) over mobile ad hoc networks (MANETs) are based on a feedback from the network, which can be expensive (require extra bandwidth) and unreliable. Moreover, most of these schemes consider only one cause of packet loss. They also resume operation based on the same stand-by parameters that might vary in the new route. Therefore, we propose two techniques for improving the performance of TCP overMANETs. The first one, called TCP with packet recycling (TCP-PR), allows the nodes to recycle the packets instead of dropping them after reaching the retransmission limit at the MAC layer. In the second technique, which is called TCP with adaptive delay window (TCP-ADW), the receiver delays sending TCP ACK for a certain time that is dynamically changed according to the congestion window and the trip time of the received packet. TCP-PR and TCP-ADW are simple, easy to implement, do not require network feedback, compatible with the standard TCP, and do not require distinguishing between the causes of packet loss. Our thorough simulations show that the integration of our two techniques improves the performance of TCP over MANETs.",

note = "Funding Information: Marwan Krunz received the Ph.D. degree in electrical engineering from Michigan State University in July 1995. He joined the Univer-sity of Arizona in January 1997, after a brief postdoctoral stint at the University of Maryland, College Park. He is currently a profes-sor of electrical and computer engineering. He previously held visit-ing research positions at INRIA (Sophia Antipolis, France), HP Labs (Palo Alto, California), Paris VI University, and US West (now Qwest) Advanced Technologies (Boulder, Colorado). Dr. Krunz{\textquoteright}s research is in communications technology and networking, with particular emphasis on optimal resource allocation, adaptive control, and distributed proto-col design. Recently, he has been involved in projects related to cogni-tive radio networks (CRNs); power/rate/spectrum adaptation for wire-less networks; medium access control (MAC) design in wireless ad hoc networks; network protocols for wireless systems with adaptive MIMO, beam-forming antennas, and UWB capabilities; topology man-agement and clustering in location-unaware sensor networks; adaptive video streaming over wireless networks; routing, fault monitoring, and detection in all-optical networks; path selection for MDC (multiple description coding) based media streaming; quality-of-service routing; WWW caching and prefetching; and adaptive packet encapsulation. Previously, he worked on packet scheduling and buffer management in switches and routers, QoS provisioning, effective-bandwidth theory, traffic characterization, and video-on-demand systems. He has published more than 150 journal articles and peer-reviewed conference papers, and holds three US patents. Dr. Krunz is an IEEE Fellow (class of 2010). He is a recipient of the National Science Foundation CAREER Award (1998-2002). He served on the editorial board for the IEEE/ACM Transactions on Networking, and currently serves on the editorial boards for the IEEE Transactions on Mobile Computing, and the Computer Communications Journal. He was a guest co-editor for special issues in IEEE Micro and IEEE Communications Magazines. He served as a technical program chair for the IEEE INFOCOM 2004 Conference, Hong Kong, March 2004, the IEEE International Conference on Sensor and Ad hoc Communications and Networks (SECON 2005), Santa Clara, Sep. 2005, the IEEE International Symposium on a World of Wireless, Mobile and Multimedia Networks (WoWMoM 2006), Buffalo, New York, June 2006, and the 9th Hot Interconnects Symposium, San Francisco, California, August 2001. He has served and continues to serve on the executive and technical program committees of numerous international conferences, and on the panels of several NSF directorates. He was a keynote speaker at the Fourth IEEE Workshop on Wireless Mesh Networks (WiMesh 2009), Rome, June 2009, and an invited panelist at various international conferences (e.g., INFOCOM 2009, SECON 2009, etc.). He gave tutorials at premier wireless networking conferences (e.g., MobiCom, Mobi-Hoc). He frequently consults for companies in the telecommunications sector.",
