Investigating the Impact of Mobility Models on MANET Routing Protocols

Abstract

A mobile ad hoc network (MANET) is a type of multi-hop network under different movement patterns without requiring any fixed infrastructure or centralized control. The mobile nodes in this network moves arbitrarily and topology changes frequently. In MANET routing, protocols play an important role to make reliable communication between nodes. There are several issues affecting the performance of MANET routing protocols. Mobility is one of the most significant factors that have an impact on the routing process. In this paper, FCM, SCM, RWM and HWM mobility models are designed to analyze the performance of AODV, OLSR and GRP protocols, with ten pause time values. These models are based on varying speeds and pause time of MANET participants. Different node parameters such as data drop rate, average end-to-end delay, media access delay, network load, retransmission attempts and throughput are used to make a performance comparison between mobility models. The simulation results showed that in most of the cases OLSR protocol provides better performance than other two routing protocols and it is more suitable for networks that require low delay and retransmission attempts, and high throughput.

The Collaborative Mobility Model based on the Archimedean Spiral of Group Intelligence

“…Based on realistic application scenarios where nodes are subject to gravity and inertia after being released from a high altitude in a 3D scene, the following assumptions are made about nodes. (1)The nodes move independently of each other and without power, but all possess an energised attitude to fly. (2)After the node is released in the air, it is able to do inertial flight under the action of air resistance and Earth's gravity by relying on the energy gained, and the speed of movement of the node after release is v, v ∈ (v min , v max ).…”

“…The mobility model is most commonly used in the simulation of ad hoc networks. The mobility model of the nodes directly determines the topology of the network, which in turn has a major impact on the performance of the network [1]. In addition, since different mobility models are often applicable to different application scenarios, the adoption of suitable mobility models is important for studying the performance of various protocols for ad hoc networks and their evaluation and analysis [2].…”

RSSGM: Recurrent Self-Similar Gauss–Markov Mobility Model

“…The performance of mobility models in mobile ad hoc networks (MANETs) has also been investigated [28,[36][37][38]. For instance, Abdullah et al [37] evaluated the RWP model on various routing protocols: ad hoc on-demand distance vector (AODV), optimized link state routing (OLSR), and Geographic Routing Protocol (GRP). The evaluation was conducted under four different configurations for speed and pausing time: fast car, slow car, race walk, and human walk models.…”

Optimization Technique for Approximate High Impact of Node Density for Two Hop Relay Manets

“…SK Meera Sharief et al [16] have identified the impact between the routing protocols using buffer considering the buffer as finite and infinite through simulation for different network parameters. Ako Muhammad Abdullah et al [18] have investigated the impact of mobility models (FCM, SCM, RWM and HWM) on MANET routing protocols (AODV, OLSR and GRP). The performance metrics are varied with speed, pause time and node parameters such as data drop rate, average end-to-end delay, media access delay, network load, retransmission attempts and throughput.…”
