Mesh network dynamic routing protocols

The main course of this paper will be to assess the applicability of dynamic routing protocols in Mesh networks. In the process, evaluation criteria were identified, an evaluation method was developed and implemented using simulation in the NS-3 environment, a method for describing a topology has been proposed, and an experiment was conducted using the method on a simulated network topology. The experiment showed the possibility of applying the method to evaluate such indicators as throughput and error rate, loss coefficient, delay variation and network delay. The results obtained allowed to conclude about the applicability of particular routing protocol to specified topology with specific network quality requirements

Performance evaluation of dynamic source routing protocol with variation in transmission power and speed

Mobile ad-hoc network (MANET) is a set of mobile wireless nodes (devices) which is not rely on a fixed infrastructure. In MANETs, each device is responsible for routing its data according to a specific routing protocol. The three most common MANET routing protocols are: dynamic source routing protocol (DSR), optimized link state routing protocol (OLSR), and ad-hoc on-demand distance vector (AODV). This paper proposes an efficient evaluation of DSR protocol by testing the MANETs routing protocol with variation in transmission power at different speeds. The performance analysis has been given using optimized network engineering tools (OPNET) modeler simulations and evaluated using metrics of average end to end delay and throughput. The results show that the throughput increases as the transmission power increases up to a certain value after which the throughput decreases, also the network work optimally at a certain transmission power which varied at different speed
