Abstract
The Mobile Ad-Hoc Network (MANET) incorporates a collaborative networking scenario, where dynamic host movement results in frequent topology changes. In MANET, nodes cooperate during route establishment, and the data packet must travel from source to destination through multi-hop intermediate links. The nodes in a MANET can be localized in a restricted zone, where manual intervention to set-up fixed infrastructural support is practically infeasible. However, cooperative packet forwarding and data transmission is quite a common scenario in the context of MANET. Still, due to dynamic topological changes, weak, intermittent links appear within one-hop communication. This leads to a higher possibility of packet drop events and also increases the retransmission scenario, which affects the energy performance of the network. Addressing this issue, the study models a novel and intelligent packet forwarding approach based on the game theory, where trust evaluation in terms of node reputation factor also plays a very vital role. The approach also enforces an incentive modelling to stimulate the cooperation between mobile nodes during the MANET routing scenario. The system is designed and developed with evolutionary game perspectives to meet the Quality of Services (QoS) requirements. The experimental analysis supports the proposed modelling design aspects. Also, it exhibits that the reputation and trust-based game increases the utility of packet-forwarding strategy with high throughput and negligible network overhead.
Highlights
Mobile Adhoc Networks (MANETs) refer to a special type of wireless ad-hoc network, where nodes are mostly mobile and move independently in any direction with self-organizing capabilities [1], [2]
The trend of the emphasized research in MANET is mostly concerned about the timely execution of the task with reliable data transmission and reception even if unreliable radio-link is present during the communication scenario [6]
From the time complexity view-point, if the packet forwarding algorithm follows the notion of distributed computing approach, it should be a light-weight computational model that can be deployed for sustainable service delivery execution; besides having a positive influence on controlling the delay constraints in critical applications of MANET
Summary
Mobile Adhoc Networks (MANETs) refer to a special type of wireless ad-hoc network, where nodes are mostly mobile and move independently in any direction with self-organizing capabilities [1], [2]. The unreliable communication link increases the probability of packet drops and retransmission events This means the utility factor of different packet forwarding strategies will go down and will affect the energy and throughput performance in MANET eventually [7], [8]. By addressing the design loopholes in the traditional data forwarding approaches, the proposed study realizes that it is essential to design a mechanism that can effectively encourage a node in packet forwarding even if the transmission happens through unreliable links. This way, a high throughput success rate is envisioned with maximum packet-delivery ratio.
