Performance comparison of two location based routing protocols for ad hoc networks

Abstract

In recent years, many location based routing protocols have been developed for ad hoc networks. This paper presents the results of a detailed performance evaluation on two of these protocols: Location-Aided Routing (LAR) and Distance Routing Effect Algorithm for Mobility (DREAM). We compare the performance of these two protocols with the Dynamic Source Routing (DSR) protocol and a minimum standard (i.e., a protocol that floods all data packets). We used NS-2 to simulate 50 nodes moving according to the random waypoint model. Our main goal for the performance investigation was to stress the protocols evaluated with high data load during both low and high speeds. Our performance investigation produced the following conclusions. First, the added protocol complexity of DREAM does not appear to provide benefits over a flooding protocol. Second, promiscuous mode operation improves the performance of DSR significantly. Third, adding location information to DSR (i.e., similar to LAR) increases both the network load and the data packet delivery ratio; our results conclude that the increase in performance is worth the increase in cost. Lastly, our implementation of DREAM provides a simple location service that could be used with other ad hoc network routing protocols.

“…The results collected from simulations have been shown in [71][72][73][74]. The typical value of the average delay is a few hundred milliseconds in the studied network scenarios.…”

Performance Analysis of MANET Routing Protocols in the Presence of Self-Similar Traffic

“…We simulated the steady-state conditions of the network with three types of traffic models; namely CBR, Pareto and Exponential [4,5,6]. These were generated using the tool cbrgen.tcl [14], with the following parameters:…”

“…It must be noted, however, that the packet transmission starts 1000 seconds after nodes start to move to reduce the variability in the simulation results [4,6]. The traffic models generator was properly seeded to generate around 30 source connections, which will aggregate more data traffic towards the end of simulation causing a burstier traffic to occur.…”

“…A significant number of research efforts have been devoted to investigate Mobile Ad Hoc Networks (MANETs) over the past few years [5,6,16]. Interest in MANETs is due to their promising ubiquitous connectivity beyond that is currently being provided by the Internet.…”

“…The routing protocols selected for the present evaluation study include Dynamic Source Routing (DSR), Ad hoc On-Demand Vector Routing (AODV) and Optimized Link State Routing (OLSR). These have been selected because they have been widely investigated in the literature over the past few years [4,5,6,7,19].…”
