The characteristics of multi-hop wireless networks such as mobility link layer contention high bit error rate asymmetric path network partition hidden exposed nodes and dynamic routing do not fit the requirements of TCP for a good reliable data delivery. Here we want to provide an overview of the research progress in applying TCP algorithms to the problem of multi-hop conditions and characteristics. The scope of this review will encompass core methods and protocols of TCP over multi-hop networks including cross-layer network layer protocols and medium access control MAC layer protocols. The research contributions in each field are systematically summarized and compared allowing us to clearly define existing research challenges and to highlight promising new research directions. The findings of this review should provide useful insight into current multi-hop networks literature and be a good source for anyone who is interested in TCP in wireless approaches or related fields. Keywords TCP multi-hop wireless network survey 1 Introduction The rapid advancement in portable computing platforms and wireless communication technology has led to making it an integral part of the Internet. As the Internet users requirements of flexibility and mobility increase multi-hop wireless networks have become the best solution to satisfy these requirements. These networks are complex distributed systems that consist of
