Hybrid energy and trust efficient reactive routing mechanism for MANETs

Abstract

The facilitation of quality of service (QoS) under routing in Mobile Ad Hoc NETworks (MANETs) is a challenging issue due to its resource constraints, bandwidth sharing and topology dynamism. Moreover, security is considered as another complex issue of provisioning QoS as the prevalence of maliciousness nodes introduces all types of threats to the MANETs. In spite of a diversified number of mechanisms contributed for securing MANETs, majority of the solutions are potential in preventing some particular category of attacks or facilitate security by sacrificing the QoS cost. In this paper, Hybrid Energy and Trust Efficient Reactive Routing Mechanism (HETERRM) was proposed for ensuring trust-oriented QoS routing process that integrates QoS trust and social trust. This proposed HETERRM first relies on the process of mitigating maliciousness nodes by incorporating a trust mechanism that is capable in different packet forwarding misbehavior and reliable path discovery for facilitating trustworthy communication. This proposed HETERRM further aids in selecting the optimal forwarding node based on quality of channel, quality of link and residual energy to quantify the packet forwarding potential. The simulation experiments of the proposed HETERRM are conducted using ns-2 is evaluated using energy consumptions, packet delivery ratio and overhead.
