“…An ad hoc network is a dynamically changing network of mobile nodes that communicate deprived of the support of any type of fixed structure. There is a straight communication among adjacent devices, but communication between nonadjacent devices that work such as routers, requires routing algorithms, for instance destination sequenced distance vector (DSDV), adhoc on-demand distance vector (AODV) and dynamic source routing (DSR) (Royerand Toh, 1999;Noorani et al, 2008;Ball et al, 2016). Because of the character of MANETs (i.e.…”

In the internet congestion control, transmission control protocol (TCP)-Vegas is a source algorithm that provides better performance. However, it has two main issues: first one is rerouting and unable to identify updation of round-trip time (RTT) when changes occurred in the network, these two problems leads to affects the performance of Vegas. These drawbacks persist mostly in the Vegas estimation process of the propagation delay, i.e. BaseRTT. In this paper, we proposed a novel algorithm that uses the cuckoo search optimisation algorithm for selecting the optimal value of BaseRTT. Also, our proposed algorithm has dynamically considered slow start algorithm based on the estimation in real time, the available bandwidth and adjust decrease/ increase rate in congestion avoidance phase for a particular network environment. Simulation results have shown that our proposed algorithm can effectively avoid packet losses and attain the maximum throughput when compared with existing algorithms.

“…For example, just to name a few, (Thenmozhi and Rajaram, 2011;Qamar and Manoj, 2010;Kumar et al, 2004;AlHanbali et al, 2005;Al-Hunaity et al, 2007;Luo et al, 2009). Recently, researchers have started to take a look at the interaction between transport protocols and other networking layers, for example (Ahuja et al, 2000;Kim et al, 2005;Seddik-Ghaleb et al, 2006;Dyer and Boppana, 2001;Noorani et al, 2009). Although many efforts have been established to study the relationship of TCP and different MANET routing protocols, but, to the best of our knowledge, there is no existing work that investigates the interaction between equation-based congestion control transport protocols and the type of MANETs routing protocols.…”

Problem statement: Although many efforts have been done on studying the behaviour of TCP in MANET, but the behaviour of TFRC remain unclear in MANET. The purpose of this research is two folds. First, we studied the behaviour of TFRC and TCP over AODV and DSR as the underlying routing protocols in terms of throughput, delay and jitter. The second objective was to identify whether MANET routing protocols have an impact on transport protocols or not. Approach: Network Simulator 2 (NS-2) was used to conduct all of the experiments, i.e., TFRC over AODV, TFRC over DSR, TCP over AODV and TCP over DSR. We created 30 nodes on a 1000×1000 m location area and each node was assigned CBR traffic, transport protocol and routing protocol. In order to simulate the nodes mobility, we implemented a Random Waypoint mobility model with varying speeds of 5, 10, 15 and 20 m sec −1 (m/sec) with a 10 sec pause time. Results: We observed that TFRC throughput increases almost 55% when using DSR as its routing protocol, but TCP throughput has no significant difference with different underlying protocols. However, in terms of jitter and delay, both routing protocols, i.e., AODV and DSR have the impact of more than 50% on TFRC and TCP. Conclusion/Recommendations:The results obtained also show us that TFRC or TCP should choose AODV as its routing protocol because it has less jitter which is one of the critical performance metrics for multimedia applications.

This paper conduct a comprehensive simulation study on the behavior of TCP-friendly Rate Control (TFRC) protocol over Ad-Hoc On Demand Vector (AODV) routing protocol and Dynamic Source Routing (DSR) protocol. The aim are first, to measure the performance of TFRC in terms of throughput, delay and jitter. The second objective is to identify which Mobile Ad-Hoc Network (MANET) routing protocols work well with TFRC. We conduct the experiment by sending multimedia streaming traffic carried by TFRC over AODV and DSR respectively. Random-Waypoint mobility model is used for both experiments. Results obtained shows that in average TFRC over AODV has more throughput and less delay as compared with TFRC over DSR. However, in terms of jitter, TFRC over DSR gives better result.
