“…In multi-hop wireless networks using IEEE 802.11, most packet losses experienced by TCP are due to packet drops at the link layer caused by hidden terminal effects but not due to network congestion [5] [9]. In addition, ACK packets in the reverse direction from receivers compete for channel access to the same medium with data packets, frequently causing ACKs not able to reach the source in time, thus TCP executing its congestion control algorithms responsibly.…”

This paper studies TCP throughput performance in IEEE 802.11-based multi-hop wireless networks where nodes can have different physical transmission modes, e.g., modulation schemes and packet transmission rates. The physical transmission modes affect the link layer transmission performance, which further affects the TCP throughput performance. Selecting the TCP congestion window size is important for improving TCP throughput. We use simulation to demonstrate the effect of different physical layer modes on the TCP throughput performance and find the optimal TCP window size upper bound.

“…Moreover, the channel availability is limited within the given transmission range. So, in case of buffer overflow and link layer contention, the TCP segments will be dropped [4]. As a result of link layer contention, the packets being transmitted gets dropped off, indicating the fact that network is getting overloaded or congested.…”

Wireless Mesh Networks(WMNs) is generally composed of radio nodes in the mesh topology. WMNs consists of mesh client, mesh router and gateway connected to a wired network. Each client and router relay messages to the gateway for communication. WMNs is widely used recently in many areas can provide extended coverage based on multi-hop communication and ubiquitous communication at any time and any location. However the competition and collision between each node to transmit data is inevitable when the same channel is used for transmission. The transmission opportunities and the throughput of nodes located far from gateway decrease more if the communication channel is accessed based on competitive CSMA/CA scheme using DCF(Distributed Coordination Function) provided by IEEE 802.11 MAC. In this paper, we improve the performance of the TCP fairness and throughput of the nodes with more than 2 hops by applying various algorithms for controlling contention window values. Also, we evaluate the performance using ns-2 simulator, According to the results, proposed scheme can enhance the fairness characteristic of each node irrespective of data to the gateway.
